Subject: lxc: fix setmem effect on a running LXC machine
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=c87f268a369eb0f275781abbf446731f6c23f522;p=libvirt.git

lxc: fix setmem effect on a running LXC machine

When user calls setmem on a running LXC machine, we do update its cgroup
entry, however we neither update domain's runtime XML nor
we update our internal structures and this patch fixes it.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1131919
