Oh, my recipe wasn't quite right - when you
sudo sed -i 's@/var/lib/lxc@/data/lxc@' /var/lib/lxc/r2/config
that also changes the path to r2's fstab. So either you have to

Now my question, could not lxc (at boot) setup a fixed MAC addr for the host
port?
Yeah, given how bad this was for libvirt/qemu I'm surprised I've not seen
this happen in lxc - but I haven't, and noone else has reported it.
Since you mention lxcbr0, I assume you're using ubuntu? Until we

Hello,
I have a question regarding containers and their supporting rootfs. Is there
an option for lxc-create that will use a default path (or other backing
store) as rootfs?
I understand that by specifying -B ... it will try to

hi,

Hm. Mine is simply called 'lxc', and that works. So it sounds like I'm
doing something wrong in parsing the zfsroot, but I can't offhand see
in the code where.
Could you run this through

This is really cool, first off. I'd like to extend the built-in
overlayfs backing store support a bit, but there will also be
room for more powerful setups using mount hooks. I'd like to
add your mount hook into the set of listed examples, if you don't
mind.

Dear serge,
Sorry for my delayed reply :)
Problem Still persists with selinux disabled. Maybe it is not the memory
problem because that my machine has 2TB memory and 8 x E7-8830 cpus.

Hi,
is it possible to add a additional network interface (either physical or
vlan) to a running lxc container.
I didnt find any pointers if this is possible.
See lxc-device.
