Re: [ovirt-users] Bring back "Migrate to other Cluster" feature in GUI
Hi Micheal,
Thanks for your reply.
I know it was there because of the migration between EL6 and EL7 but
you can simply "park" VM's on different clusters which can be very
handy when you need to move clusters, etc or really migrate cluster.
I never had issues with differences between clusters, the GUI warned
me always for it when I by accident selected the wrong cluster. As
that is a human mistake I think you cannot blame such great feature
for admins that don't have their administration in right shape and
rely on everything what's in "their portal".
Maybe we need to start a wide vote to see who thinks it's usable ?
Cheers,
Matt

Hi Matt,
unfortunately it was a very frequent cause of mistakes which lead us to the decision to
hide it more. Such change for running VM cannot be supported reliably unless you manually
make sure that all the settings match exactly on both clusters. These checks are feasible
when the VM is Down, which is still allowed.
The problems originating from incorrect usage are simply not worth it as they are
difficult to diagnose, and sometimes quite obscure. This feature was really only meant for
EL 6 to EL 7 transition - which is over for 3 releases now - as a workaround to
then-non-existant InClusterMigration policy
We will still keep it in API, though I’d discourage you from using it. If you need to
correct the provisioned cluster you better do it the supported way of Edit VM and power
cycling the guest, that’s the only way we can effectively test it and guarantee the
functionality.
Thanks,
michal
