             Summary: [VMware] VR loses DHCP settings and VMs cannot obtain IP after HA recovery
                 Key: CLOUDSTACK-9719
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9719
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: VMware
            Reporter: Suresh Kumar Anaparti
             Fix For: 4.10.0.0


ISSUE
=========
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.
