[ovirt-users] Disabling migration when there is a problem with storage

[Dan Yasny]

When a storage error occurs, VMs should pause, not migrate. However, if the
VMs were io-idle, then pause (qemu EIO) might have not been triggered
before hosts started dropping into non-op.
...which triggered a migration storm for HA-enabled VMs, racing with VMs
pausing somehow (can't tell without diving into the logs for sure).

I haven't seen it happen in any of my setups, probably a new issue
