[libvirt-users] Server 2016 locked in paused state

Hi all,

I have a number of production Windows servers on KVM/DRBD and two of 
them are Server 2016.  Both these guests have started exhibiting the 
same behaviour where they enter a paused state and will not resume.

The behaviour is the same whether I use virsh or virt-manager. My only 
recourse is to force the guest off and start it again. This brings the 
host up temporarily where upon it pauses again. It could be minutes or 
hours but it always returns to being stuck in this paused state.

I'm not seeing anything much in /var/log/kern.log or syslog - perhaps 
I'm missing the clue.

Has anyone else seen this and or can you advise me where I should be 
looking to find the cause of this?

Sincerely

--

Paul, I experienced this when the server images partition
filled. It may not be your case but it's worth to check it out.

Yeah, that was my first idea as well, you might have ran out of space.  Check
the pause reason for the domain. I'm not sure how to do that in
virt-manager,
but you can do that using `virsh domstate --reason $domain`.  You can also check
libvirt logs for something like EIO or I/O error, but that will just be a debug
message saying that QEMU sent us something like that.

Hi Francesc,

thanks for the input.
> Paul, I experienced this when the server images partition
> filled. It may not be your case but it's worth to check it out. Indeed that was my first thought too.  I have them backed by LVM so I 
did an lvmextend but it didn't seem to work until I created new DRBD 
meta-data (not relevant to this group though I guess). It has stayed up 
since doing that; so far...

So it may have been a little PEBKAC here...

Thanks for the pointer.
