> Unneeded VR reboot after successful live migration
> --------------------------------------------------
>
> Key: CLOUDSTACK-8545
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8545
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Affects Versions: 4.4.3, 4.5.1
> Reporter: René Moser
> Priority: Blocker
> Fix For: 4.6.0
>
>
> The changes committed to fix #7994 are causing a lot of downtimes due
> unneeded VR reboots, it fixes an edge case:
> In case of live migration fails and the VR will be rebooted from VMware HA,
> it VR network config will get lost.
> This edge case seems to be fixed in a more reliable way in 4.6 with
> persistent router config. Live migration on VMware rarely fails with such a
> small VM like the VR is, with low RAM and no I/O. The current implementation
> does a router restart in every case just to make "sure" config is there. This
> causes downtime up to 30 minutes in production environments.
> Therefore I suggest to revert the changes in 4.5.2 and 4.6.
