Dears, 

i'm facing an issue with libvirtd, when issuing the command "libvirtd" i'm getting the following error:

# libvirtd

That means either there already is another libvirtd running or the previous one died unexpectedly without removing this PID file. You can distinguish these two via 'pgrep libvirtd' which either gives you the very same PID as the one in the PID file (=libvirtd is running) or nothing and than you should be safe to remove the file and start libvirtd again. However, if libvirtd keeps failing to initialize, there might be a misconfiguration problem (and libvirt bug as well since we ought to remove PID file before quiting).

Thanks alot!

i have the same PID process  using "pgrep libvortd" however, i still have the error occuring almost every day, could it be because of Libvird bug or for ex: libvirt wend a short  period sleep?

Might be it is a bug, suggested open a ticket with vendor
