[Pkg-libvirt-maintainers] Bug#905350: Have you enabled the memory and swap cgroup managers?

[Peter.Chubb at data61.csiro.au]

Hi,
	To control memory with libvirt-lxc you need to have the memory controller and
	swap account controllers active.  This means (on Debian)
	adding:
	     cgroup_enable=memory swapaccount=1
	to GRUB_CMDLINE_LINUX_DEFAULT in  /etc/default/grub
	doing
		sudo update-grub
	and then rebooting.

	You are probably seeing lots of messages in your logs like:
   Failed to open file '/sys/fs/cgroup/memory/machine/lxc-41320-containername.libvirt-lxc/memory.memsw.usage_in_bytes
        in your logs.
