Dear All,

ONE version: 5.2.1
The VMs are running as usual.
Just the state is in UNKNOWN state.
Whenever I recover -> success the VMs, it shown RUNNING but changed back to UNKNOWN after a while.

Below is the error message from oned.log

Hi,

You can try to restart the libvirtd service on the host.

Can you please post the content of:

  1. /etc/one/oned.conf

  2. /etc/one/vmm_exec/vmm_exec_kvm.conf

  3. Also check the status of SELINUX (should be OFF or Disabled) and IPTABLES(should be Flushed by -F)

  4. try to reboot the worker & front and then check (after checking point-3)

Since the VMs are going to runn state, did you ever try to login to those guests? Like RDP or SSH?

Hi,

The problem solved after restarting the libvirtd service on the host.

Thanks

I know it is an old thread but very helpful, If somebody have the same problem.

  • all VMS state unknown
  • the host showing " Error executing kvm.rb", as such impossible to manage the VMs from opennebula anymore.
  • no networking issues between opennebula and the host
  • all VMs are still online on the host

Restarting libvirtd service on the host as stated in the previous posts did fix the issue.
sudo systemctl restart libvirtd

In my case I was able to see the errors on the host by using
sudo systemctl status libvirtd
