If so, then could you try the following:
ethtool -K <nic name> lro off
Do this for all the 10G intel nics and check if the problems still exists
Kind regards,

Hi all,
Since we upgraded to the latest ovirt node running 7.2, we're seeing that nodes become unavailable after a while. It's running fine, with a couple of VM's on it, untill it becomes non responsive. At that moment it doesn't even respond to ICMP. It'll come back by itself after a while, but oVirt fences the machine before that time and restarts VM's elsewhere.
Engine tells me this message:
VDSM host09 command failed: Message timeout which can be caused by communication issues
Is anyone else experiencing these issues with ixgbe drivers? I'm running on Intel X540-AT2 cards.
