hi Dwight, Sorry for the late reply. Probably you were right and there was something in the bash initial configuration/profile. It is deployed by puppet, that's why I missed it.

Eg.: $ ssh container echo $ scp file container: It's waiting for something and I could not find out. Hi Tamas, sorry, I know you brought this up before and I wasn't sure if you got it solved or not. First off the host doesn't know the container by name so unless you've done something special the resolving of container isn't going to just work (ie. ping container should fail Yes, I know about that.

Also, the openssh-clients package has to be installed in the container for scp to work. For now you can manually install it in the container using yum or the -r option to the template when creating a new OL container. I'll submit a patch for the template that includes that package by default so scp in/out will work out of the box. Unfortunately disabling GSSAPI* and UseDNS options doesn't help. I experience the same problem. BTW, our system works fine, DNS is fine, Ubuntu and Debian containers, HW based OL installations and everything works as they expected. In fact OL containers are working fine, except this issue. For I can run Oracel DB inside one. If you tell me, how to debug, what to do, I can try that.

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 'strace -f -odebutfile' and look in debugfile
for the exec of 'zfs create'?
hi,
Sorry, I could get back to this just now:
log.103022:execve(/sbin/zfs, [zfs, create,
-omountpoint=/var/lib/lxc/test123/rootfs, tank/lxc/test123], [/*
21 vars */]) = 0
From cli it works fine.
I can send the whole log file, if you want.
Yes, please do - to me personally depending on the size, to spare the
list.
Shame on me, I absolutely forgot to answer this email.
This one works fine:
# lxc-create -n eee -t ubuntu -B zfs --zfsroot tank/lxc
But:
# lxc-create -n eee -t ubuntu -B zfs
cannot create 'lxc/eee': no such pool 'lxc'
lxc-create: Failed to create backing store type zfs
lxc-create: Error creating backing store type zfs for eee
lxc-create: Error creating container eee
The problematic command:
execve(/sbin/zfs, [zfs, create, -omountpoint=/tank/lxc/eee/rootfs,
lxc/eee], [/* 31 vars
*/]) = 0
Of course it's not OK, since the last parameter should be tank/lxc/eee.
It seems to me, that either -B zfs should require --zfsroot or the default
value for zfsroot
should be tank/lxc as it is in the help:
--zfsroot=PATHCreate zfs under given zfsroot
(Default: tank/lxc))
I've attached the strace log.
Sorry for the mess again...
ps.: Can we make at least configurable the mountpoint, so it can be set to
the root of the container?
I'd like to call that something different, as it has completely
different behavior. We could do the same for btrfs and zfs.
At container start, we want $rootfs to be treated as a simple dir
backed container. At clone time, we want to bypass manual copying
of files and backing store - but not of the updating of the files -
in favor clone of all of $lxcpath/$container/.
I'm not sure, I see the problem here. Can you elaborate it?
Even if config, fstab and other files outside of rootfs directory are cloned to
a new fs, they can
be overwritten, deleted or anything else.
Is the problem something around this?
Thanks,
tamas

This is the first container on the list.
Any idea?

hi,
Although the the package is not here, I downloaded the raw file from github,
and the function is
indeed fixed.
Though still there is the FUTEX_WAIT error

[Lxc-users] Skype in a container
hi All, Is there a cookbook to run Skype in a container? I upgraded my laptop to Saucy and Skype seems to crash continuously. So I think it would be a good idea to run a Precise container with Skype. 10x tamas -- AlienVault Unified Security Management (USM) platform delivers complete security visibility with the essential security capabilities.

Re: [Lxc-users] Restarting LXC containers after power failure
On 05/06/2013 02:58 PM, David Parks wrote: We just had a datacenter power failure, upon restart of course our LXC containers were stopped. It would be just dandy if there were an LXC option to restart the containers that were already running before the sudden failure. Is there any such capability? There is no such option. You can enable containers to start automatically at boot time, see /etc/lxc/auto/ .
