[Lxc-users] LXC-Create fails after upgrade to Ubuntu 12.10 from 12.04
last week I upgraded from Ubuntu 12.04 to 12.10 and since then LXC no longer works correctly. creating a simple LXC container: sudo lxc-create -t ubuntu -n cont1 appears to be working ok until it gets to the following error near the end: Get:23 http://archive.ubuntu.com quantal-updates/main Translation-en [38.8 kB] Get:24 http://archive.ubuntu.com quantal-updates/multiverse Translation-en [587 B] Get:25 http://archive.ubuntu.com quantal-updates/restricted Translation-en [635 B] Get:26 http://archive.ubuntu.com quantal-updates/universe Translation-en [18.9 kB] Fetched 4901 kB in 11s (427 kB/s) Reading package lists...

Re: [Lxc-users] LXC-Create fails after upgrade to Ubuntu 12.10 from 12.04
And .. Yes I have flushed the cache to no avail. I've also gone as far as purging then reinstalling lxc. I also have some pre-existing containers that I now cannot start using - sudo lxc-start -n name Having tried multiple times with lxc-create I did notice that they all fail the same way with the reference to the same undefined symbol: * Reading package lists...

Re: [Lxc-users] cloud environment
Quoting Rintcius Blok (rintc...@gmail.com): Hi, Just curious. I was running an lxc-create command for ubuntu-cloud and saw this output: Configuring for running outside of a cloud environment If you want to configure for a cloud evironment, please use '-- -C' to create the container What the difference is between using '-- -C' or not, i.e. what is exactly the 'cloud environment' that is mentioned here? Since there is already some cloudy aspect implied by the ubuntu-cloud template name, I guess this is on a different level. Can someone shed some light on this? It has to do with cloud-init searching for a metadata server which can provide per-instance data. Assuming you don't have a metadata server, your container would probably never fully come up. It's something which comes preconfigured in the ubuntu-cloud images for the sake of auto-configuration in amazon and openstack clouds (i.e. not in containers, but on cloud VMs - the same image is used for both). You *could* set up your own metadata service, but I've never done it...

Re: [Lxc-users] Problem starting oneiric container in 12.10
Quoting Rintcius Blok (rintc...@gmail.com): How can I properly run an ubuntu-cloud template on 12.10 with an oneiric container? I tried this command: lxc-create -t ubuntu-cloud -n oneiric.lxc -- --auth-key $HOME/.ssh/id_rsa.pub --userdata ~/userdata.txt.gz -r oneiric This creates the container, but when I try to ssh into it it gives: Permission denied (publickey). In the container's auth.log I see lots of entries like this: getty[5015]: /dev/tty5: cannot open as standard input: Operation not permitted I googled around and saw this related thread: http://www.mail-archive.com/lxc-users@lists.sourceforge.net/msg03496.html This thread mentioned that using an older container can be the cause of it, so that could the cause in my case as well. I don't know how to work around it though in this situation. Any ideas? Also, is this a bug or am I trying something that is outside the scope of what should run out-of-the-box? Thanks, Rintcius Could be just a bug, but what is in your userdata file? -serge -- Monitor your physical, virtual and cloud infrastructure from a single web console.

I'm using 12.04 but with lxc from 12.10 (0.8.0~rc1-4ubuntu38, to be exact) and lxc-unshare works fine. Perhaps you're using a different version, or your liblxc0 is outdated? -- Fajar -- Monitor your physical, virtual and cloud infrastructure from a single web console.
