I am getting periodic VM lockups, and when I reboot I get an initramfs error. I have no idea why this is happening, and I can rollback to the most recent snapshot, but I worry that eventually it's going to bite me.
Like I mention in the title, I'm running 5.2-1, and no, no other VMs on this host or on the cluster are affected. Very low utilization on the Node. It was running on local storage, but I moved it to an NFS mount on a FreeNAS share. It's a media wiki instance, with very little utlization, but I've not been on the guest looking when it happens, I just find that it has locked the next time I access it, when it reports the file system is read-only and it hangs on reboot.
