Re: [ovirt-users] Ovirt causing strange network issues?

Hi, I've done a lot more testing today. I've narrowed the issues down to two specific VMs. When I'm running either of these two VMs I get horrific network performance. When both of those two are stopped, my network is just fine (like 99% of the time). I've been spending the day gathering

I believe you would accomplish this by setting a VM to be highly available (like the engine). Then engine makes sure this VM is up on at least one node through lease agreements (IIRC). In either case, I think this is what you want On Wed, Oct 4, 2017 at 10:25 AM, Chris Adams

Re: [ovirt-users] LVM structure

Sure. vdsm-tool should be disabling lvmetad on the host automatically. Maybe some of the hosts were fresh installed and others have been upgraded from older versions? In any case, you should be able to run on any host in maintenance mode: sudo vdsm-tool configure --force And this should

[ovirt-users] Question about cold start

I have an oVirt cluster that was hard shutdown last night (fire is bad, and firemen killed the generators for their safety). When it came back up, it did not start any VMs other than the hosted engine. Is that expected? I know this is not a normal use case, but is there a way to set VMs to
