Hi all,
     When I try to start libvirtd, using "libvirtd -d", error notification shown below:
error : virPidFileAcquirePath:345 : Failed to acquire pid file '/$HOME/.libvirt/libvirtd.pid': Resource temporarily unavailable
     Using "libvirtd -v", show:
     "libvirtd: error: Unable to obtain pidfile. Check /var/log/messages or run without --daemon for more info."
     The file "libvirtd.pid" only contains "2010" without any other infomation.
     I have checked that libvirtd has been installed in "/libvirt/sbin" with binary format by self-compiled.
     So how can I solve the problem? Or how to start libvirtd?

     Meanwhile, virsh can't search "libvirt-sock", because the libvirtd is not started successfully.

Thanks a lot!

Corey
