Re: [libvirt] [PATCH] virGetGroupList: always include the primary group

The change from initgroups to virGetGroupList/setgroups in cab36cfe71ba83b71e536ba5c98e596f02b697b0 dropped the primary group from processes group list iff the passed in group to virGetGroupList differs from the user's primary group. So always include the primary group to bring back the old behaviour. Debian has the kvm group as primary group but uses libvirt-qemu:libvirt-qemu as user:group to run the kvm process so without this change the /dev/kvm is inaccesible.
