My VM machines show UNKNOWN

All of my virtual machines show UNKNOWN. I already restarted the libvirtd in the host but it does not help. The host’s virbr0 and virbr0-nic networking is DOWN, but I could not bring it back up. Please help.

root@psera2-dell86:/etc/netplan# ifup virbr0-nic
Unknown interface virbr0-nic

I checked dmesg and found out the virtual port has issue:

Posting the VM log located at /var/log/one/<vm_id>.log could probably help. Also, the output of onehost show <host_id> where the VM is deployed will show if the host is being correctly monitored.

My vm storage systems psera2-kvms1 and psera3-dell86 have some issue with virbr0 and virbr0-nic network interface sine yesterday morning. The virbr0 and virbr0-nic show DOWN at the host systems. Will they have to be up for the Openebula virtual machines to work.

I already fixed all my vms. They are now showing RUNNING but when I logged in it shows READ ONLY filesystem.
