Re: [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.
Hi,
when probing for capabilities libvirt starts qemu with:
-pidfile $libDir/qmp-XXXXX/qmp.pid
where $libDir points to /var/lib/libvirt/qemu for system wide daemon and
$XDG_CACHE_HOME/.cache/qemu/lib/ for session daemon. qemu process is run
under user:group configured from corresponding qemu.conf
(/etc/libvirt/qemu.conf for system daemon). The defaults are distro
specific.
Hope this gives you some hint. Although, libvirt should relabel its
internal paths on daemon startup, so this smells like a bug.
