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. Michal
