Quick test without much success

Inside the guest I run this loop
while true
do
time dd if=/dev/zero bs=1024k count=1024 of=/home/g.cecchi/testfile
sleep 5
done

BTW: my home is inside / filesystem on guest that has space to accomodate 1Gb of the dd command:
[g.cecchi@ol65 ~]$ df -h /home/g.cecchi/
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_ol65-lv_root
                       20G  4.9G   14G  27% /
[g.cecchi@ol65 ~]$

After about 7 rounds I get this in messages of the host where the VM is running:

Feb  1 23:31:57 ovmsrv06 kernel: dd: sending ioctl 80306d02 to a partition!

Nothing on the other host.

I stop the dd loop and after some seconds:
Feb 1, 2017 11:32:32 PM VM ol65 has recovered from paused back to up
