About VMware HCX

VMware HCX delivers secure and seamless app mobility and infrastructure hybridity across vSphere 6.0 and later versions, both on-premises and in the cloud. HCX abstracts the distinct private or public vSphere resources and presents a Service Mesh as an end-to-end entity. The HCX Interconnect can then provide high-performance, secure, and optimized multi-site connectivity to achieve infrastructure hybridity and present multiple options for bi-directional virtual machine mobility with technologies that facilitate the modernization of legacy data centers.

For more information, see the VMware HCX User Guide in the VMware Documentation Center.

VMware HCX R143 Release Notes | 08 September 2020 | Build 16812445 (Connector), Build 16812446 (Cloud)

New Features

Scaling Out HCX in VMC with Multi-Edge SDDC

With this release, HCX is ready for VMware Cloud on AWS Multi-Edge environments, creating dedicated high-bandwidth network paths for HCX Network Extension and Migration operations. By default, VMware Cloud on AWS SDDCs use a single edge router (T0) through which all North-South traffic flows. You can configure your SDDC to be Multi-Edge using traffic groups, which create additional T0 routers. The HCX Cloud Manager detects these traffic groups and makes them available as HCX Uplink Networks.

HCX in VMC with VMware Transit Connect

With this release, HCX is ready to support Transit VIFs for HCX migration and Network Extension services. This allows HCX operations to leverage high-bandwidth, low-latency connections between SDDCs using the VMware Transit Connect service.
 

VMware HCX Integration with vRealize Network Insight

This HCX release supports integration with vRealize Network Insight 5.3 to build migration waves based on Application Discovery and Dependency Analytics. Application Groups can now be defined in vRNI and then exported using public APIs from vRNI to HCX as Mobility Groups. You then prepare for migration using the HCX Mobility Group configuration procedures.
 

General Availability for HCX with vSphere 7.0 

• This HCX release adds support for environments that use vSphere 7.0 (VDS 7.0) and NSX-T 3.0.1+.  This feature was in Preview with HCX R142.
• Summary of updates for vSphere 7.0 in this release:
  • HCX enables users to adopt VMware Cloud Foundation 4.0 as the destination environment.
  • HCX can be used with any destination environments that uses vSphere 7.0 with NSX-T 3.0.1+.
  • Limited functionality has been added for vSphere 7.0 based source environments.​
    
    vSphere 7.0 related HCX feature details are provided in the sections below. 

Migration Enhancements

• HCX has been updated to enable virtual machine migrations in the following vSphere 7.0 scenarios:
  • All HCX migration operations from source vSphere 5.5 – 6.7  to destinations built with VMware Cloud Foundation 4.0.
  • All HCX migration operations from source vSphere 5.5 – 6.7 to destinations built with vSphere 7.0 with NSX 3.0.1+.
  • Limitations from vSphere 7.0 source environments to any HCX Cloud destination:
    • All HCX migration operations are available for virtual machines with Hardware version 9 – 15.
    • Only Bulk migration operations are available for virtual machines with Hardware version 17. (This limitation should be noted when multiple connected cloud environments use vSphere 7.0.  This limitation will be addressed in a future release.
  • Migration UI Enhancement: In scenarios where a virtual machine network exists across hosts as both a NSX-T Logical Segment, and a VDS 7.0 Distributed Port Group, the HCX migration interface has been updated to only display the NSX-T Logical Segment name.   
     

Network Extension Enhancements

• HCX has been updated to enable Network Extension in the following vSphere 7.0 scenarios:
  •  vSphere VDS 5.1 – 6.7 networks can now be extended to vSphere 7.0 HCX clouds.
  • vSphere VDS 7.0 networks can now be extended to vSphere 7.0 HCX clouds. 
  • NSX-T VLAN and Overlay segments can now be extended to vSphere 7.0 HCX clouds.
  • Caveats:
    • The HCX Network Extension service creates overlay segments at the destination, this behavior is still true with vSphere 7.0 destinations.
       
• HCX Service Mesh Enhancements

• The HCX Service Mesh appliances can be deployed using vSphere 7.0 based resources and VDS 7.0/NSX-T 3.0.1 networks​.
   

Key Issues

Resolved Network Extension Issues

• PR/2404124 – Network Extension appliance redeployments fail with “portKey\\\": array contains null at index 0” error when a source extended network has ephemeral port bindings. Network Extension of Ephemeral Port Groups is not supported and is now prevented in the UI.

• PR/2444658 – Prior to this release, the Network Extension created or connected to NSX-T Fixed segments. The extension operation would fail in environments with pre-created NSX Flexible segments.

  Network Extension now succeeds with pre-existing Fixed and Flexible segments. HCX defaults to creating Flexible segments when the network does not already exist in the NSX Tier 1 Router.  HCX continues to create fixed segments when extending to a VMware Cloud on AWS SDDC.

Resolved Virtual Machine Migration Issues

• PR/2617190 – Replication-based migrations of virtual machines with multiple disks to destinations with VMFS 6 Datastores on vSphere 7.0 do not complete. The operations are stuck in the COLLECT_TARGET_SIDE_TRANSFER_STATUS state and display “Storage is locked” NFC errors in the logs.
   
• PR/2601145 – When removing a Bulk Migration or RAV switchover schedule, HCX rolls back the migration and fails with a “Replication is not enabled for the transfer” error. 
   
• PR/2551152 – When a DNS Suffix is given in the Bulk Migration Extended Options without also providing the DNS Servers, the DNS Suffix configuration is not sent to the guest OS during the Guest Customization phase.
   
• PR/2562199 – Corrected a network mapping discrepancy that causes virtual machines to be placed on the None network when performing a reverse migration.
   
• PR/2584680 – vMotion Migrations fail when the EULA section in the virtual machine OVF is more than 3 MB long.

• PR/2625494 – Fixed an issue that causes Replication Assisted vMotion (RAV) or HCX vMotion migrations to an HCX Cloud from two or more HCX Connectors to stall with a 'Waiting for Resource Availability' task.

Resolved Service Mesh Deployment Migration Issues

• PR/2515405 – Service Mesh deployments fails when static route configurations overlap with Network Profile networks without giving clear indication of the configuration error.

Resolved Virtual Machine Migration and Protection Issues

• PR/2607734 -- Fixed an issue where HCX incorrectly lists Virtual Networks during selection of target networks for network mapping of source virtual machine workloads. Virtual Networks are no longer displayed as options for target network selection.

Resolved HCX User Interface Issues

• PR/2614011 – Corrected a sorting problem that causing inventory lists to be displayed in random order in various HCX User Interfaces . The inventory lists are now correctly sorted by type and name prior to being displayed.
   
• PR/2606348 – The HCX Bulk Migration and Disaster Recovery interface incorrectly allows HCX managed Virtual Networks to be selected, resulting in virtual machines connected to the "None" network, after a Bulk migration or DR Recover operation.  These HCX networks have been filtered from the UI.

Key Issues

Resolved OS Assisted Migration Issues

• PR/2560342 - Resolved an issue where storage verifications failed for a Linux virtual machine that had a physical volume that was not attached to any volume group.  If, for example, there were 2 physical volumes, /dev/sda1 and  /dev/sdb1 and the volume group was attached to only /dev/sda1, then the HCX Sentinel agent software running on the guest virtual machine reported 2 physical volumes to the HCX Sentinel Data Receiver (SDR) appliance. The SDR tried to associate /dev/sdb1 to a volume group and since it could not, the storage verification failed. With this release physical volumes not associated with a volume group are not reported.

• PR/2587556 - Resolved an issue where the HCX Sentinel Data Receiver (SDR) appliance failed to create the storage for a Linux virtual machine that had a volume group which was not associated with any logical volume.

  If, for example, there are 2 volume groups, /dev/vg01 and /dev/vg02, and there was a logical volume only on top of /dev/vg01 and not on /dev/vg02, then the HCX SDR failed to create the storage in this situation. With this release, the HCX SDR creates the storage even when there are no logical volumes on a volume group.

Resolved Migration Issues

• PR/2513263 - Resolved an issue where the migration progress percentage and migration status was displayed incorrectly. This enhancement applies to all types of HCX migrations.

Resolved Serviceability and Usability Issues

• PR/2353393 - Resolved an issue that prevented the preview of the required firewall rules when creating a compute profile.
   
• PR/2491233 - Resolved an issue where the dynamically generated FOU tunnels established as part of an IPSec connection were not being displayed causing the tunnel status to incorrectly show as Down. This was seen for both the HCX Interconnect and HCX Network Extension IPSec tunnels.
   
• PR/2599292 - Resolved an issue that prevented the deployment of a Multi-Site Service Mesh with error "Unable to fetch NSX-T Transport Zone from Configured Compute in Compute Profile" when using NSX-T 3.0.
   
• PR/2585914 – Resolved a cosmetic issue that prevented a site paring to be disconnected when the remote peer is no longer available. The new process may take several minutes to complete validation before proceeding with the removal.
  
   

HCX R141 - Released June 26, 2020

VMware HCX R141 Release Notes | 26 June 2020 | Build 16460208 (Connector), Build 16460210 (Cloud)

New Features

OS Assisted Migration Enhancements  

• Additional OS Support
  For a detailed list of supported operating systems and OSAM requirements, see Migrating Virtual Machines with VMware HCX.
  • Support for OSAM Migration of Ubuntu 16.04 LTS and 18.04 LTS Virtual Machines on Hyper-V
    With this release, the HCX OS Assisted Migration service supports migration of virtual machines running Ubuntu 16.04 LTS 32-bit and 64-bit (BIOS/GEN-1  & UEFI/GEN-2), and Ubuntu 18.04 LTS 64-bit (BIOS/GEN-1  & UEFI/GEN-2) operating systems on Hyper-V hypervisors. 
     
  • Support for OSAM Migration of CentOS 7.8 and RHEL 7.8 Virtual Machines on KVM and Hyper-V
    With this release, the HCX OS Assisted Migration service supports migration of virtual machines running RHEL 7.8 164-bit and CentOS 7.8 64-bit 18.04 on KVM and Hyper-V hypervisors. ​
     

Serviceability Enhancements

• vCenter Alarms
  The HCX Manager maintains ongoing communication with connect.hcx.vmware.com for system licensing and heuristics. If that connection is broken, the HCX Manager now generates a vCenter alarm. 

• Force Removal of Inactive DR Protections   
  Following a failed DR Protection operation, where replication is inactive and the inventory record becomes not actionable from the UI, use the Force Remove option to delete that protection and clear all internal objects. The option may need to be run more than once, at source and destination HCX Managers. The VM will be removed from the inventory of protected VMs and it will become available to start a new DR protection.
  
  The Force Remove operation clears all protection and replication data for that VM and the option is intended to be used as a last resource only, once the underlying cause for the failure has been identified. The recommendation is to always collect the support bundle on both HCX Connector and Cloud Manager prior to executing the removal for post analysis.
   

Key Issues

Resolved Migration Issues

• PR/2441241 – Improved the data flow performance of the Host Based Replication Server (HBRSVR) to better handle VR Bulk Migration of large VMs with high data change rate.
   
• PR/2572289 – Fixed an issue causing Bulk migrations that remain in initial sync state for more than 7 days after stop receiving replication updates
   
• PR/2575521 – Fixed a rare condition where a failed vMotion or Cold migration workflow, caused by the loss of communication with the target host during the initial stages of the relocation and if aborted by the user via the UI, it may result on the removal of the source VM.

Resolved Platform Issues

• PR/2557328 – Fixed an issue with the messaging service in HCX Connector and Cloud Manager that may cause messages to be dropped unexpectedly during startup. A restart of Application service will restore the messaging service. Refer to the Troubleshooting section in the HCX documentation for more details on restarting services. The version of Kafka server included in HCX has been updated to 2.5.0 to address this and several other issues found with the previous version 2.3.1.
   
• PR/2528346 – Fixed an issue causing HCX components to send all local traffic to the default gateway when the Management and Uplink interfaces are part of the same Network Profile.

Resolved Deployment Issues

• PR/2561743 – Fixed an issue preventing deployment of the HCX Network Extension if the HCX Connector is not configured with NSX.
   
• PR/2577062 – Fixed an issue causing the failure to create or edit Compute Profiles in the VMware Cloud on AWS.

Resolved Serviceability and Usability Issues

• PR/2373573, PR/2392861, PR/2431276 – Enhanced the enforcement of the communication between the HCX Connector/Cloud Manager and the HCX Service. If the systems remain disconnected over the 7 days grace period, any migration workflows that started prior to the expiration date will be serviced to completion but no new migrations will be allowed until the communication is re-established.
   
• PR/2567151, PR/2482028 – Fixed an issue where the HCX plug-in shows duplicate entries for various screens (service mesh, migration data, site pairings) in environments that are configured in Hybrid Linked Mode.

• Mobility Optimized Networking
  • Mobility Optimized Networking (MON) integrates HCX Network Extension with NSX-T policy-based routing and distributed routing to enable migrated virtual machines to reach other virtual machines optimally, without tromboning between sites. Currently released for Early Adoption (EA), MON requires the HCX Enterprise license and is supported in environments with NSX-T 3.0 running at the destination site, independent of the cloud provider. MON can be configured per network or per virtual machine, toggled on or off for existing extended networks, and selected for when to switch over: immediately or upon a specified virtual machine event.
  • Network Extension with Proximity Routing is deprecated and no longer available with only limited support for existing users.
     
• Network Extension Enhancements
  • Extending Networks from Source Sites with both vSphere and NSX-T Distributed Switches
    If your source site has vSphere Virtual Distributed Switches (vDS) and NSX-T Distributed Switches (N-VDS) with virtual machine networks that you want to extend, you can select either or both types of switches for Network Extension. Previously, you could select one, but not both types of switches.

    • This update does not include support for NSX-T 3.0 with vSphere 7.0  
       
• Migration Enhancements
  • Detection of High-Activity Virtual Machines in HCX Mobility Groups
    HCX migrations have two phases: Transfer and Switchover. Virtual machines experiencing very high disk writes can cause Transfer intervals where the virtual machine change data exceeds the achievable migration throughput.  This high-activity condition can prolong the Switchover phase beyond the scheduled migration window, disrupting the migration operation.  With this release, HCX uses VMware vCenter Server heuristics and internal Recovery Point Objective data to provide early detection of high-activity virtual machines, to calculate the impact on migrations, and generate Critical Alerts for at-risk migrations.

  • Clearing the Migration History
    This release includes the Archive option for clearing migration activity. The Archive option clears all selected migrations. It can be used with failed, cancelled, and completed migrations. Clearing the migration history updates the HCX Dashboard migration counters but does not remove the migration related details from the HCX log files.

  • Force Clean Up for Failed or Cancelled OS Assisted Migrations 
    Following a failed or cancelled migration, you can use the Force Clean selection in the Migration UI to clear internal HCX operations and processes manually from source and destination sites. Originally released with the HCX R138 Service Update with support for Bulk, vMotion, and Replication Assisted Migration, Force Clean is now available with OS Assisted Migration.

• Traffic Engineering Enhancements
  • HCX Service Mesh Updated to Display Enabled Traffic Engineering Features
    The HCX Multi-Site Service Mesh UI now displays enabled Traffic Engineering features (Application Path Resiliency and TCP Flow Conditioning). You also can view which appliances are using the Traffic Engineering features by selecting Appliances in the Service Mesh UI.

• HCX Platform Mobility Enhancements
  In this release, the platform mobility enhancements introduced in HCX release R135 are available for Bulk and vMotion migrations in VMware Cloud Director (vCD) clouds. For more detailed information regarding Platform Mobility Enhancements, see the HCX R135 Service Updates section of these release notes.

• HCX Platform Mobility Enhancements
  With this release, the underlying VMware mobility HCX platform has been enhanced for improved robustness and resiliency. The HCX migrations can now run on top of this platform, providing a unified user experience across the migration types supported by HCX. This new mobility platform enables migrations to resume from the certain checkpoints in an event of restarts and hence providing better continuity of the migration execution. Also, the migration dashboard has been updated for improved migration visualization and management. The UI helps a user understand the distinct migration phases: initial data sync and initial copy, continuous data sync, and eventually the switchover.
  
  If you are using APIs, these platform enhancements offer a rich set of RESTful APIs to manage the migration lifecycle. To get the benefits of running migrations on the enhanced mobility platform, you must transition to these new mobility APIs. The mobility APIs are documented in the Mobility section of HCX API documentation: https://<hcxip>/hybridity/docs.
  
  In this release, the platform mobility enhancements are available only for Replication Assisted vMotion and Bulk migrations.
  
  Cisco Nexus 1000v is no longer supported with HCX due to these enhancements.

HCX R124 - Released August 7th, 2019

VMware HCX R124 Release Notes | 07 AUG 2019 | Build 14339004 (Enterprise), Build 14339009 (Cloud)

New Features 

• HCX Enterprise Services Available with NSX Datacenter Enterprise+ Deployments

With this update, HCX Enterprise licenses are available for purchase to NSX Enterprise Plus customers. Access to the HCX Enterprise services requires an additional license.

This first delivery of HCX Enterprise is an add-on SKU available for customers using NSX Enterprise Plus. HCX Enterprise for VMC and for VCPP partners is planned for a future release.

             HCX Enterprise Features:

                         OS Assisted Migrations (OSAM)

This release provides general availability of OS Assisted Migration capability for migrating application workloads from an OpenStack/KVM environment into a vSphere environment. See User Guide for a list of supported guest VM Operating Systems.

                        Replication Assisted vMotion (RAV)

This new migration option combines the scalability benefits of bulk migration (parallelism, scheduling, resiliency) with the vMotion capability to migrate with no downtime.

                         Integration with Site Recovery Manager (HCX + SRM)

With the combined solution, DR backup and recovery can leverage the HCX hybrid interconnect to optimize bandwidth and connectivity, secure VMs in transit and stretch networks to simplify IP address management for recovered VMs. HCX accelerates replication processes by eliminating incompatibility issues across networks and storage.

• Updated HCX Mobility Services Platform

Improvements have been made to the way migration services are orchestrated internally and executed visually in the operator interface.  The HCX migration interface has been restructured, separating the Virtual Machine copy (Transfer and Placement), the final sequence (Switchover), and Extended Options as distinct components of the migration operation. The platform changes are building blocks for the OSAM and RAV migration options, and for upcoming capabilities. The HCX 3.5.1 installer on downloads.vmware.com has been incremented to version 3.5.2.

 

• New vRealize Operations Management Pack for HCX 

New HCX metrics added will be available with the HCX Management Pack for VROPS version 5.0.  It will be released in the VMware Solutions Exchange on 12 Aug 2019.

 

• Improvements to the HCX for SDDC to SDDC Mobility in the VMware Cloud on AWS (In Preview)
  
  With this release the HCX for SDDC to SDDC Mobility in the VMware Cloud on AWS is closer aligned to how HCX with NSX Enterprise Plus pair the source and target HCX Manager, in terms of firewall requirement.  Current users of this feature will have to configure firewall rules to direct communication between the source and target HCX Managers over TCP port 443 instead of any other IP address that they might have configured before.

 

Key Issues

• Resolved HCX Interconnect Deployment Issues

PR/2280004 – Service Mesh deployment or resync failures will now be displayed in the HCX UI if some services fail to install or resync while others succeed. Previously, the entire operation would be displayed as successful.

VMware HCX R113 Release Notes | 21 JAN 2019 | Build 11921388 (Enterprise), Build 11921386 (Cloud)
 

New Features 

• HCX Interconnect Multisite Service Mesh (Experimental)

  This release includes experimental access to the new Interconnect Multi-Site Service Mesh. The new interconnect provides various serviceability and usability enhancements: 

  • A unified view is presented for the selected source and destination HCX sites. 
  • Interconnect uplinks, management and vMotion networks can be defined once, then consumed on-demand as the site to site topologies change. 
  • Datastores can be combined into consumption pools to better support large scale Interconnect deployments.
  • Enhanced Service Mesh scale out enables Interconnect components to be deployed per cluster.
  • Designed to allow modular addition of upcoming Cloud to Cloud services.
  • New parallel execution model accelerates Interconnect deployments, reducing component deployment time across the connected sites.  
  • New lockless model ensures parallel configuration during network stretch operations.
  • Required firewall rules are displayed graphically in the unified view to ease configuration activity.
    
    Recommendations: 
    The Multisite Service Mesh should be enabled only in non-production deployments while the feature is experimental. 
    
    Caveats: 
    Existing HCX Interconnect components are not compatible with the Multisite Service Mesh. Converting existing HCX Interconnect components into HCX Multisite Service Mesh components is not available while the feature is experimental.
     
• ​HCX Guest Customization for Bulk Migrations

  HCX now includes Windows and Linux guest customization as part of HCX Bulk migration.  The following virtual machine settings can be set during the bulk migration operation:

  • Virtual machine's hostname.  
  • Virtual machine vNIC IP address, Network Mask, Gateway and DNS Server.
    
    ​
• Updates to HCX Diagnostics Tools
  
  The command perftest all has been added to the HCX Central CLI.  This new command uses the HCX Interconnect performance tools to run all perftest diagnostic commands as a single operation. Specifically, it executes perftest uplink , perftest ipsec and perftest site, pertest wanopt (if Wan Optimization is enabled) and measures the transport level latency per link.  
  
   
• Improvements for vCloud Director-based HCX Installations
