Probably for the same reason we enforce all VMs disks to be on the
same storage domain. Habit.
Eliminating this dependency would be part of the
feature to allow VMs to
have their disks on multiple storage domains.
But I also think it make sense, for the hibernation file to be in the
same SD as the system disk. There's also a higher chance that domain
will be online and available to the host.
Y.
Is it possible for ovirt-engine to identify which disk is the system disk?
What should the algorithm be for determining a storage domain to
hibernate a diskless VM?
It seems like things would be simplified if we did not restrict
ourselves and could use any available storage domain regardless of
whether the vm has disks or not.
