[libvirt-users] Cannot create PID file

Hi Fellow users I've just compiled latest libvirt and qemu, both from their respective official repositories. Libvirtd starts perfect, but when I try to start a domain using the virsh console, I get the following: virsh # start --domain win8.1 error: Failed to start domain win8.1 error: internal error: Failed to start QEMU binary /usr/bin/qemu-system-x86_64 for probing: qemu-system-x86_64: cannot create PID file: Cannot open pid file: Permission denied I'm not sure where to look at. Any hint would be much appreciated. Regards, Nicolas Iglesias
