[one-users] Failed to acquire pid file '/var/run/libvirtd.pid': Resource temporarily unavailable - error when run /usr/sbin/libvirtd start

[Hector Sanjuan]

Hi,

I don't have problems starting libvirtd while VMs machines are running.  
However, last time I tried to launch a kvm machine  when a VirtualBox one  
was running it failed. With a kvm machine running and trying to start a  
VirtualBox one I got nice kernel backtraces in my screen and hard freezes.  
So no, doesnt seem such a good idea to run VBox and kvm in the same box.
