[one-users] onehost problem with kvm

[Jaime Melis]

Hi Andrea,

there seems to be a problem with the kvm information monitor driver.
To help us diagnose it better, could you please execute the following
in the worker node as the oneadmin user, and paste us the output?

virsh -c qemu:///system nodeinfo

regards,
Jaime
