Hi,
i've recently migrate from a kvm farm to Ovirt, by the way : excellent product.
But i'm stuck on a little problem.
I want to be able to dump a VM memory (forensic purpose) but i does not manage to do it.
With kvm i've used the commande : "virsh dump VM out.dump", but with ovirt
virsh is in read only and unable to do the dump .
I look vdsClient, but it does not seem able to do this job.
Someone could help me please?
Thank you.

Search the list. People have asked before how to get r/w access to
libvirt. There is a hacky way by adding a user and password and I think
there is a tool to just do that.
Had a quick google:

Shouldn't read access suffice for this purpose?
this should be possible with "virsh -r dump" for read only mode.
No authentication needed :)

Have you tried using "-r" ?
virsh -r dump VM out.dmp
I know it works to list the VMs.
virsh -r list
