unfortunately, the VMs are running storage domains too (NFS) so it'd take those down I believe ... i'll try w/o stopping vdsm first ... on one that hopefully doesnt run too many critical apps at the time ..

i'll report back how it went if anyone's interested :)

Subject: Re: [Users] save to restart libvirtd ?

would that stop any of the running VMs ?

it shouldn't, but if you have ovirt engine running, make sure that power management not active for this host,

since after timeout (usually 1 minute) when vdsm is down, the host will be fenced (restarted) - then the vms will surely stop..

look at http://www.ovi= rt.org/Automatic_Fencing for more info about automatic fencing in engine.
