-------------------------------------------------
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.
