Hi Nir,
thank you.
So, can I use a Ceph backed VM with a lease on gluster?
Also if I detach network from the node hosting the VMs it will not =
migrated to another host.
Regards
Matteo

I=E2=80=99ve a setup that uses Ceph through ovirt for VM storage.

Is it a specific setup that I=E2=80=99ve missed?

Hi Matteo,
=20
When power management is not available, we cannot do failover to other =
host.
=20
In 4.1 you can use a VM lease for your HA VM, enabling failover =
without power
management.
=20
Note that the lease cannot be on Ceph storage domain, you will have to =
add
other type of storage for the leases, since we don't support
leases on =
ceph yet.

Please check the vm-leases feature page for more info:
