Hello,
I’m an Exchange Server VM that’s going down to suspend without possibility of recovery. I
need to click on shutdown and them power on. I can’t find anything useful on the logs,
except on “dmesg” of the host:

So something really went crazy. The VM is going down at least two times a day for the last
5 days.
At first I thought it would be an hardware issue, so I restarted the VM on other host, and
the same thing happened.
About the VM it’s configured with 10 CPUs, 48GB of RAM running oVirt 4.3.10 with iSCSI
storage to a FreeNAS box, where the VM disks are running; there are a 300GB disc for C:\
and 2TB disk for D:\.
Any ideia on how to start troubleshooting it?
Thanks,
