The SDDC provider in VMware Integrated OpenStack with Kubernetes, intended for deployments without an existing VMware Integrated OpenStack instance, will be deprecated in a future major release. For new VMware Integrated OpenStack with Kubernetes deployments, use the OpenStack provider.

Open Source Components for VMware Integrated OpenStack 5.0

The copyright statements and licenses applicable to the open source software components distributed in VMware Integrated OpenStack 5.0 are available on the Open Source tab of the product download page. You can also download the source files for any GPL, LGPL, or other similar licenses that require the source code or modifications to source code to be made available for the most recent available release of VMware Integrated OpenStack.

Known Issues

The known issues are grouped as follows.

VMware Integrated OpenStack
  • E-W traffic does not travel between the VMs booted under the virtual-wire type provider network.

    If a user directly creates provider network using virtual-wire and does not create spoofguard policy, then E-W traffic will not travel between the VMs booted under this provider network.  

    Workaround: Create a spoofguard policy and add virtual-wire to this spoofguard policy. Then create a provider network of type virtual-wire.

  • Hostname that starts with a number results in "java.io.IOException" error

    The OMS server does not support any hostname that starts with number. The error "java.io.IOException: DNSName components must begin with a letter" appears if the hostname starts with a number.

    Workaround: None. For more information, see the JDK upstream issue: https://bugs.openjdk.java.net/browse/JDK-8054380

  • Failed to launch instances due to "ResourceProviderAggregateRetrievalFailed: Failed to get aggregates for resource provider with UUID xxxxxxxxxxxxxxxxxx"

    You cannot launch instances on a compute node where an existing tenant VDC was deleted. For example, the operation fails if you:

    1. Have tenant VDCs on a compute node before starting the nova-compute service.
    2. Start the nova-compute service, then delete one or more of the tenant VDCs.
    3. Attempt to launch an instance on the same compute node.

    Workaround: Restart nova-compute service on the compute node.

  • Unable to deploy OVA file using vCenter 6.7 H5 web client

    When attempting to deploy the VMware Integrated OpenStack OVA using the vCenter 6.7 HTML5 web client, the VMware Integrated OpenStack vApp fails to power on and the UI displays the error: "The virtual machine has a required vService dependency 'vCenter Extension Installation' which is not bound to a provider."    

    Workaround. Use the ovftool command to deploy the OVA files using the FLEX-vsphere-web-client. 
    NOTE: This is known issue for vCenter 6.7 HTML5 web client and is documented in the vSphere 6.7 Release Notes: https://docs.vmware.com/en/VMware-vSphere/6.7/rn/vsphere-esxi-vcenter-server-67-release-notes.html. Also, a KB for this issue is: https://kb.vmware.com/s/article/55027

  • Deleting compute nodes out of order then attempting to add a compute node results in an error

    Earlier VMware Integrated OpenStack versions only supported deletion of compute nodes in order of largest to smallest number. For example, with three compute nodes: VIO-compute-0, VIO-compute-1,VIO-compute-2, you would delete VIO-compute-2, VIO-compute-1 first. If you did not delete the nodes in this order, then adding a node later would generate an error.

    Workaround: The VMware Integrated OpenStack 5.0 UI supports node deletion in any order. However, the old node deletion and addition error checking code still exists. To work around the problem, delete nodes in order from largest to smallest node number.

  • Inaccessible OpenStack deployment due to failure in the data store where nodes are located

    In an HA deployment with nodes located in a single data store, if the data store fails, the entire deployment is not accessible.

    Workaround: To work around the problem, try to fix the failed data store and recover its data. After the node VMs are back in the vCenter Server, restart the OpenStack deployment. If data is not recoverable use the viocli recover command to restore the failed nodes.

  • Keystone endpoint health status appears with a red X

    After configuring internal_api_protocol in the custom.yml file to enable encryption, the Keystone endpoint does not reconnect with the new Keystone URL. On the OpenStack Configuration page in the vSphere Web Client, the state of the endpoint health is in error with a red X.

    Workaround: Select the Keystone endpoint and click the pencil icon to update the configuration. Scroll down to the Update Endpoint screen and perform the following steps:

    1. Change the URL to https.
    2. Enter the admin password.
    3. Click the Update button.
  • Nova-compute service fails to start following upgrade to VIO 5.0

    A user deletes a nova compute node in VIO 4.x, then adds a new nova compute node with the same vCenter Server and same cluster. After upgrading to 5.0, the nova-compute service fails to start with "ERROR nova ResourceProviderCreationFailed" in /var/log/nova/nova-compute.log.

    Workaround: Perform the following steps to remove the nova compute node from the database.

    1. Find the MOID of the deleted compute node.
    2. Log into MySQL on the database node.
    3. Switch to the nova_api database with the SQL command use nova_api:
      1. In the "resource_providers" table, remove the resource_provider record with the MOID of the deleted compute node.
      2. In the "host_mappings" table, remove the host record for the deleted compute node.
  • Delete router interface ends with timeout

    When concurrent heat stacks are deployed with shared-type NSX routers which is the default deployment, router interface deletion can timeout. Timeouts may be: neutron_client_socket_timeout, haproxy_neutron_client_timeout, or haproxy_neutron_server_timeout.

    Workaround: While timeouts can be tuned or increased, do not use shared-type routers in environments with frequent changes to network resources, for example where resources are frequently added or deleted. Use either an exclusive-type router if NAT/FIP is required, or use a distributed-type router.

  • Attempting to re-add a deleted compute node with tenant VDCS fails

    After successfully deleting a compute node with tenant VDCS, attempting to re-add it fails with a "Failed to create resource provider" error in /var/log/nova/nova-compute.log.

    Workaround: After deleting the compute node, perform the following steps to remove it from the database before re-adding it.

    1. Find the MOID of the deleted compute node.
    2. Log into to MYSQL on the database node.
    3. Switch to the nova_api database with the SQL command use nova_api and remove the resource_provider record with MOID of the deleted compute node and all its children from the "resource_providers" table.
VMware Integrated Openstack with Kubernetes
  • Authentication fails with a username or domain containing '\'.

    The Keystone authentication plugin uses the backslash character as a separator to encode the domain name and username in a single string . If there is an additional backslash in either the    domain name or username, the Keystone authentication plugin will not decode the domain name and username correctly.

    Workaround: Use domain names or usernames that do not include the backslash character.

  • Failed to delete cluster in ERROR state

    If the infrastructure is out of resources, cluster creation, healing, or scaling will fail and the cluster will fall into an ERROR state.

    Workaround: To correct this problem, perform the following steps:

    1. Run bash on the toolbox container
    2. Use the OpenStack client to delete hosts in the ERROR state.
    3. Re-run the command: vkube cluster delete
