What's in the Release Notes

The release notes cover the following topics:

Overview of VMware Telco Cloud Infrastructure OpenStack Edition

VMware Telco Cloud Infrastructure™ — OpenStack Edition is the next evolution of VMware vCloud® NFV™, a modular NFV platform. The world’s leading Communication Service Providers (CSPs) rely on this platform to develop modern cloud computing stacks to support new revenue streams while lowering costs. The ETSI-compliant NFVI platform supports a broad set of VNF applications creating a large ecosystem for CSPs to deliver innovation at a rapid pace and scale. The consistent horizontal architecture of the NFVI platform enables CSPs to deploy various network functions and services for 4G and 5G networks, from core to edge. Furthermore, the same infrastructure components are used in VMware Telco Cloud Platform, sharing the tried-and-true infrastructure DNA. This empowers CSPs  to evolve their telco cloud deployments seamlessly from IaaS to CaaS, without common upgrade dependencies.

New Features

Virtual Infrastructure Manager – VMware Integrated OpenStack

VMware® Integrated OpenStack simplifies the OpenStack cloud infrastructure deployment by streamlining the integration process. VMware Integrated OpenStack delivers out-of-the-box OpenStack functionality and easy configuration workflow through a deployment manager that runs as a virtual appliance in vCenter Server.

  • OpenStack Train: VMware Integrated OpenStack 7.0 is based on the Train release of OpenStack.
  • OpenStack Features:
    • SR-IOV NIC redundancy for network connectivity HA: Allows scheduling vNIC provision from different pNICs. 
    • Neutron Trunk services: Allows multiple networks to be connected to an instance using a single vNIC. Multiple networks can be presented to an instance by connecting it to a single port. For information about how to use trunk services, see the documentation in OpenStack Community.
    • Octavia LBaaS: This OpenStack Octavia project is integrated into this OpenStack release.
    • IPv6 for Octavia LBaaS with IPv6 members.
    • NSX-T VRF-lite as External network
  • Control Plane Enhancement:
    • Patch Management: Built-in patching capability without requiring a blue/green upgrade procedure.
    • Public API: API for managing the deployment of VMware Integrated OpenStack 7.0.

Carrier-Grade Networking

In Telco Cloud Infrastructure, VMware NSX-T Data Center 3.0 provides the following new Telco Carrier Grade networking features:

  • Multicast: NSX-T 3.0 introduces support for multicast using Protocol Independent Multicast - Sparse Mode (PIM-SM) and IGMPv2. 
  • Enhanced Data Path
    • Performance optimizations: Data plane forwarding has been further improved.
    • Additional Controller Support: Intel(R) Ethernet Controller E810 family 
  • L3 Networking
    • VRF Lite: Provides multi-tenant data plane isolation through Virtual Routing Forwarding (VRF) in Tier-0 gateway. VRF has its own isolated routing table, uplinks, NAT, and gateway firewall services. Check the maximums for the number of VRFs and sizing in the VMware Configuration Maximums tool.
    • L3 Ethernet VPN (EVPN): Provides the northbound connectivity option to advertise all VRFs on an NSX Tier-0 gateway through MP-BGP EVPN AFI (Route Type 5) to a Provider Edge and maintain the isolation on the data plane using VXLAN encapsulation by using one VNI per VRF.
  • IPv6
    • NAT64: Offers a transition mechanism from IPv4 to IPv6. It provides the stateful network address translation from IPv6 to IPv4 following the standard RFC 6146.
    • Stateful DHCPv6: NSX now supports the stateful delivery of IPv6 addresses and associated parameters through the NSX native DHCP server hosted on Edge nodes.

Resolved Issues

  • PSOD on ESXi host having ENS enabled N-VDS with High latency sensitivity VM

    This issue is fixed in NSX-T Data Center 3.0.2.

  • VMware Integrated OpenStack Cluster stays at reconfiguring status after enabling designate with Infoblox and Microsoft DNS server.

    This issue is fixed in VMware Integrated OpenStack 7.0.

  • vROps Management Pack for OpenStack 5.1 Not Supported with OpenStack 7.0

    This issue is fixed in the latest Management Pack for OpenStack 7.0.

Known Issues

  • Addition of VM Disk Failed After Upgrading vCenter Server in VCHA Configuration

    If you upgraded vCenter Server in the VCHA configuration from release 6.7 to 6.7 U3 or from 6.7 U3 to the latest patch (such as 6.7 U3f/U3j), the addition of disks to VMs backed by vSAN datastore fails with the following error:

    PBM error occurred during PreReconfigureCallback: Fault cause: vmodl.fault.SystemError

    Workaround: Follow the instructions in the KB article 76065.

  • Management vCenter Server Not Populated After Restoring the VMware Integrated OpenStack Backup

    After restoring the backup of VMware Integrated OpenStack, the management vCenter Server is not populated in the OpenStack Management Server (OMS) configuration page.

    Workaround: Follow the instructions in the KB article 79722.

  • VMware Update Manager Failed to Remediate Hosts

    When you upgrade vCenter Server at the cluster level using VMware Update Manager, the ‘Task In Progress’ error occurs during host remediation. This error occurs only when VMware vSphere Replication is configured with vCenter Server.

    Workaround: Do one of the following:

    • Use esxcli commands to patch each ESXi server sequentially.
    • If you are using VMware Update Manager, follow these steps:
      1. Follow the instructions in KB75321.
      2. Patch hosts using VMware Update Manager.
  • Load Balancers of Previous VMware Integrated OpenStack Versions Not Listed in the Latest Version

    The Horizon UI of VMware Integrated OpenStack 7.0 does not list the load balancers that are created in previous versions of VMware Integrated OpenStack. The Horizon UI shows the following error:

    Error: Unable to retrieve load balancer

    Workaround: Use the CLI to retrieve or modify the load balancer details.

  • NSX-T Logical Segments and T0/T1 Gateways Not Populated in vRLI Dashboards

    The NSX-T logical segments and T0/T1 gateways created using the Policy UI (Networking tab) are not populated in vRealize Log Insight (vRLI) dashboards.

    Workaround: None

  • Some Widgets of VMware Integrated OpenStack 7.0 Not Populated in vRLI Dashboards

    Some widgets such as Nova, Cinder, and Glance of VMware Integrated OpenStack 7.0 are not populated in vRLI dashboards.

    Workaround: None

  • pNIC Failover Not Happening on Bare Metal Edge

    The pNIC failover does not happen on the bare metal edge, if the active pNIC is down on the bare metal edge host.

    Workaround: Make the pNIC active on the bare metal edge host.

  • Backup Restore File of VMware Integrated OpenStack is Deleted While Deleting the OS Deployment

    When you delete the OS deployment, the VMware Integrated OpenStack backup restore file in Content Library is also deleted.

    Workaround: Keep the backup in a different location or folder before deleting the OS deployment.
