When a domain needs an access to some device (be it a disk, RNG, chardev, whatever), we have to allow it in the devices CGroup (if it is available), because by default we disallow all the devices. But some of the functions that are responsible for setting up devices CGroup are lacking check whether there is any CGroup available. Thus users might be unable to hotplug some devices: virsh # attach-device fedora rng.xml error: Failed to attach device from rng.xml error: internal error: Controller 'devices' is not mounted Signed-off-by: Michal Privoznik <mprivozn@xxxxxxxxxx> --- src/qemu/qemu_cgroup.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+)
