hello:
Now that I've had my ovirt cluster running for about a month and a half, I

Hi all:
I'm trying to set up a new ovirt cluster. I got it "mostly working"

I set up a FreeSwitch-based VoIP server as a host on my cluster, and am

rather, tell Ovirt all the "right settings" to optimize that VM to VoIP).

Well, it turned out it was 100% of one core, percentage reported took into
account how many cores the VM had assigned. Rebooting the node did fix the
problem.
Just to be clear, the "proper" procedure for rebooting a host in oVirt is
to put it in maintence mode, ssh to the node, issue the reboot,

I had the same problem when I upgraded to 4.2. I found that if I went to
the brick in the UI and selected it, there was a "start" button in the
upper-right of the gui. clicking that resolved this problem a few minutes
later.
I had to repeat for each volume that showed a brick down for which
issues, its a serious bug in the software, even if its
mis-handled exceptions. Is this correct?
