Subject Re: [DISCUSS] Out of Band VR migration, should we reboot VR or not?

This is a VMware specific problem, right?
We could also limit the fix to this hypervisor only.

In case the VR is moved out of band (say as part of Vmware DRS), all network rules are lost.
Rebooting VR from CS re-applies all the rules. Either the reboot is done manually from UI/API
or automatically as was done as part of CLOUDSTACK-7994.

I haven't looked at the aggregate command. If it can be used to apply rules on VR without
a reboot then that should work as well.

Hi all,

Recently a behaviour was reported for ACS 4.5.1, where out of band VR migration would cause
rebooting of VR. It seems this is a desired behaviour as per this issue:

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:

Please share your comments on whether if we should revert the fix or not, and the best way
to do it. Thanks.
