[libvirt-users] Problem with libvirt daemon

Hello, I have a problem with the libvirt daemon. I have a little php script which should connect with libvirt, but it won't. When I try to start the libvirt daemon I get this error (using the command libvirtd --listen): 2011-11-09 19:35:18.095: 3560: info : libvirt version: 0.9.7 2011-11-09 19:35:18.095: 3560: error : virPidFileAcquirePath:345 : Failed to acquire pid file '/var/run/libvirtd.pid': Resource temporarily unavailable So the daemon won't start and isn't started yet. If I check if the service is running with ps -ef | grep libvirtd I get this output: root 2865 1 0 15:50 ? 00:00:00 /usr/sbin/libvirtd -d root 3149 1 0 19:17 ? 00:00:00 libvirtd -d root 3206 1 0 19:17 ? 00:00:00 libvirtd -dl root 3300 1 0 19:20 ? 00:00:00 libvirtd --listen --daemon root 3356 1 0 19:21 ? 00:00:00 libvirtd --listen --daemon root 3564 3077 0 19:36 pts/0 00:00:00 grep --color=auto libvirtd Here you can see that the service isn't running. How can I fix this problem. There is a .pid file in the /var/run/ directory. I already deleted it and used the command libvirtd -daemon -listen but it won't start. It doesn't show any output but when I use the ps -ef command, I see that the service is not running. Can you please help me? With kind regards, Wouter.
