Hi all,
I got this in my Debian updates today. It relates to libvirt, and its
use of cgroups:
If you're using cgroups make sure you're using a different mount per cgroup
controller (cpu, memory, ...) that is mounted to
/sys/fs/cgroup/<controller>.
This can be achieved using mount_cgroups in /etc/default/libvirt-bin or by
using systemd. Using a single mount point /sys/fs/cgroup for all controllers
will no longer work and will prevent vms from starting. See
http://libvirt.org/cgroups.html
for more information. If you're not using cgroups nothing has to be changed.
Essentially this means that the cgroup structure libvirt will demand
is different to that which util-vserver demands. This will cause
trouble for those with mixed environments. Is anything being done
util-vserver side to adapt to this?
Cheers,
Ben
