An ovirt-node machine reboots and shows in the ovirt-manager page:
NonResponsive
Then I went to the Admin console page of this node machine and had the
following error reported：
1.Failed command for onn-pool00-tpool.

I am currently using ovirt 4.3.6, what is the best way to recover if

What I hope to do is that the two NICs of the virtual machine are on the same
network segment as the two NICs on the node. For example, the two IPs on node
are 172.16.100.10 and 172.16.131.20 respectively. I hope the effect is the IP
of the virtual machine on node is also 172.16.100.* and
I check the status of ovirt-provider-ovn. It's inactive.

I use the command "virsh dominfo ovirt-win10-03" to find that the CPU of
ovirt-win10-03 is 8 cores.
Then I view the graphical interface of the win10 virtual machine, use the
command "systeminfo" to display only two CPUs. What is the cause?

At present, there is a ovirt-node1, which has two physical network cards. The
IP of one network card is 172.16.91.10, and the IP of one network card is
172.16.131.10. If I want to create a logical network card, both logical network
cards are on the same network as the physical network card. For
Jayme , how can I create another network in ovirt ?
