If I create an ordinary (not lvm backed) container, then shuffle things

Hi All
I have a container running over a XFS logical volume, and would like to
employ user-level disk quota.
This doesn't work, but it seems like I need something like:
mount -o remount,uquota /var/lib/lxc/vm0/rootfs/
The change seems to stick:
/dev/mapper/lxc-vm0 on /var/lib/lxc/vm0/rootfs t

Thanks Serge. This is the distro:

And a stable version of quantal before that.
I will start by looking for
Hi All
I have an intermittent, but crippling, problem on a raring EC2 instance
(also on quantal). Its a (raring) lvm-backed container --- I use cgroups
directly (via /sys/fs) and iptables in the instance (not sure if that's
relevant at all).
Occasionally, when stopping or starting the containe

I understand that I can limit the RAM of a single container via

I use "lxc.aa_profile = unconfined" to get the NFS client to work in a

Is that the best approach?
Thanks

Hello All,
Is there any known means for a non-root user, who is ssh'd into a
container, to attack the host (e.g. read a file, reboot the machine ...)?
From what I have read the (potential) trouble seems to be with root
users. Is that true?
Many thanks,
Gary

Hi
Going back through the list, I couldn't find whether this has been resolved.
I had a similar problem today with a little over 40 containers:
# lxc-start -n gary
lxc-start: Too many open files - failed to inotify_init
lxc-start: failed to add utmp handler to mainloop

Hi
Would greatly appreciate any help getting the sshd template working on
my Ubuntu 9.1 host.
I can ssh to and from the container and host when the container is
generated by:
lxc-execute -n foo2 -f /usr/share/doc/lxc/examples/lxc/lxc-veth-gb.conf
/bin/bash
Here I have slightly modified the exam
