DagSonsteboSB opened a new issue #3156: VMware standard vSwitch port group configuration when ESXi host is added to CloudStack
URL: https://github.com/apache/cloudstack/issues/3156
 
 
   ##### ISSUE TYPE
    * Improvement Request
   
   ##### COMPONENT NAME
   * VMware vSphere / ESXi under CloudStack
   
   ##### CLOUDSTACK VERSION
   * Any
   * Tested in CloudStack 4.9 and 4.11
   
   ##### CONFIGURATION
   * New ESXi host being added to existing cluster
   
   
   ##### OS / ENVIRONMENT
   * Any
   
   ##### SUMMARY
   * A newly added ESXi host added to an existing ESXi cluster utilising standard vSwitches will come online without any port group configuration.
   * Port groups are added when a VR and / or VM is started on that host
   * However if VMware native HA is utilised and an HA even occurs then a non-configured host can be chosen as failover destination without CloudStack being in the decision chain. At that point VMs will fail to fall over.
   * The scenario is not unfeasible - it is not uncommon to either rebuild a host or introduce a new host as part of a a HA scenario. A repeat of the HA event will then lead to VMs being left offline.
   
   Suggested solution:
   * Upon ESXi host addition the existing cluster should be checked for port group configurations, and all required port groups configured on the new ESXi host.
   
   
   ##### STEPS TO REPRODUCE
   * Configure a native HA VMware vSphere cluster in CloudStack.
   * Put all hosts apart from one into maintenance mode.
   * Now add a brand new, unconfigured host into the cluster.
   * Power down the remaining ESXi host with running VMs out of band / pull power / ungracefully shut it down.
   * Monitor the native VMware HA failover.
   * VMs will fail to migrate to the newly configured host.
   
   ##### EXPECTED RESULTS
   * Once added to a CloudStack managed cluster all ESXi hosts should be configured and ready to take on workloads, even if these are triggered out-of-band from CloudStack.
   
   ##### ACTUAL RESULTS
   * HA failover to unconfigured host will fail.
