Today I've upgraded my LXC testbed to the most recent kernel and found
libvirt-lxc broken again (sic!).
Remounting /proc/sys/ is failing.
Investigating into the issue showed that commit "mnt: Implicitly add
MNT_NODEV on remount as we do on mount"
is not mainline.
Why did you left out this patch? In my previous mails I explicitly
stated that exactly this commit unbreaks libvirt-lxc.
Now the userspace breaking changes are mainline and hit users hard. :-(
I can confirm that userns with libvirt-lxc and 3.17-rc* is broken and
the (kernel) commit in question fixes the issue.
Best,
Matthias
