Public bug reported:
if you try to start a qemu/kvm guest from inside a container crated by lxc
create -t ubuntu, it will fail with something like:
error: Failed to start domain my.img
error: unable to allow device /dev/full: Operation not permitted
$ lxc create -t ubuntu -n lv1
$ lxc-console -n lv1
# login here
% apt-get install qemu-kvm
% apt-get install dbus # bug 918343
% apt-get install libvirt-bin
% qemu-img create -f qcow2 disk.img 1G
% virsh define libvirt.xml
% virsh start mytest
from a working qemu guest, I see:
# cat /sys/fs/cgroup/devices/libvirt/qemu/myname/devices.list
c 136:* rw
c 1:3 rw
c 1:7 rw
c 1:5 rw
c 1:8 rw
c 1:9 rw
c 5:2 rw
c 254:0 rw
So I think we need to add access to that list of devices. (haven't testd
this all the way yet).
