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

Hello,
I'd like to know if there is a way to configure ovirt (oVirt Engine
Version: 3.5.0.1-1.el6) to NOT migrate VM's when there is a problem with
attached storage.
Scenario - our storage array that hosts all our VM disks failed. When that
happened, ovirt attempted to migrate running VM's from one host to another.
Unfortunately this left many of the VM's in a 'migrating to' state that
could only be resolved by restarting the HV's
I'd prefer to have ovirt simply hang the VM's until disk IO returns.
Is this possible?
