Suresh Kumar Anaparti commented on CLOUDSTACK-9719:
---------------------------------------------------
Test scenarios:
- Enable cluster HA after VR is created. Now stop and start VR and check its
restart priority, should be High.
- Enable cluster HA before VR is created. Now create some VM and verify that VR
created must have High restart priority.
Issue validation steps:
- Create a VMware setup with a cluster having 2 ESXi hosts and Enable HA at
cluster level in vCenter.
- Creat a Network offering with DHCP and source NAT
- Create few VMs using network created above and Ensure that router VM is
created with restart priority set to High.
- Make the ESXi host (where router VM is running) unreachable.
- Verified that router VM is first migrated to other host and VMs acquire IP
via DHCP.
> [VMware] VR loses DHCP settings and VMs cannot obtain IP after HA recovery

>
> After HA being triggered on VMware, some VMs fail to acquire DHCP address
> from a VR. These VMs are live migrated as part of vCenter HA to another
> available host before the VR and couldn't acquire DHCP address as VR is not
> migrated yet and these VMs request failed to reach the VR.
> Resolving this requires manual intervention by the CloudStack administrator;
> the router must be rebooted or the network restarted. This behavior is not
> ideal and will prolong downtime caused by an HA event and there is no point
> for the non-functional virtual router to even be running. CloudStack should
> handle this situation by setting VR restart priority to high in the vCenter
> when HA is enabled.
