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. -- Met vriendelijke groeten / With kind regards, Johan Kooijman _______________________________________________ Users mailing list [email protected]<mailto:[email protected]> http://lists.ovirt.org/mailman/listinfo/users This message (including any attachments) may contain information that is privileged or confidential.
