Hi all, If I understand correctly, this is also in 4.4.3 (and the upcoming 4.4.4). The report on user list: http://markmail.org/message/nth7qck27s2chwoc?q=VMsync+issues+with+VRs%3F<http://markmail.org/message/nth7qck27s2chwoc?q=VMsync+issues+with+VRs?>
As VPCs are non-redundant, a sudden reboot impacts users. I’d like to do this in a non-impacting way. Why out-of-band migrations? When patching XenServer at scale, it is much faster to set the cluster to “unmanaged” in CloudStack and “evacuate” a XenServer host directly (i.e. making it empty by live-migrating), turn off HA, disable it, patch, reboot, enable, and do this for all hypervisors in the pool. Finally, turning HA on again and set CloudStack to “manage” the cluster again. I have scripted this, so we can automatically patch clusters at scale. In CloudStack 4.4.2 this works and the database gets updated with the current information on where VMs live. In CloudStack versions which include this fix, CloudStack will reboot all routers “to be sure”. This prevents me from doing maintenance without impact. I’d propose to either limit the fix to VMware, or come up with a way that does not require a reboot. CLOUDSTACK-6047 sounds interesting, just curious how to do it in 4.4 for now.

It seems this is a desired behaviour as per this issue: https://issues.apache.org/jira/browse/CLOUDSTACK-7994 It was shared on the thread on users ML that since CloudStack now supports aggregate commands for VR, this behaviour is unnecessary. The VR in 4.5+ supports aggregated execution of commands on VRs to allows us to achieve eventual consistency of VR state without actually rebooting it, see this for details: https://issues.apache.org/jira/browse/CLOUDSTACK-6047 Please share your comments on whether if we should revert the fix or not, and the best way to do it.
