[ovirt-users] Master Doamin - Ovirt 3.6 - hoted engine

[Dariusz Kryszak]

Thanks Simone,
I'll wait for official 3.6.3 release.
That's cool that it
has been fix patch released.
I'll appreciate for workaround procedure
and I think that other users too.
Do you have that procedure?

I've tried do this by myself, but finally I've redeployed whole environment.
I've changed records in the postgres database. (table storage_domain_static)
It is not enough. I've try to change metadata files on the storage but after that storage domains has been red :-(.
