@Jim – I have not migrated to LXC as I also find isolation of guests is not as complete as I prefer. Personally I continue to use OpenVZ or KVM.

I would advise you file a bug report or post to the LXC mailing list, the mailing list is quite active and you may find a better answer there.

I have tried the nova-compute-lxc. Since VMs use the single kernel, one of them make the system crash may cause all of them to crash together. Is this a downside of it? Can we do something to prevent this from happening?

Thanks.

lxc-start: no configuration file for ‘/sbin/init’ (may crash the host)

@Bram – LXC is in rapid development and if you want to be “informed” you should join the mailing lists.

Buggy meaning guest do not always work as expected, there is a lack of documentation, tons of user scripts to manage various features without a good quality central method of managing guests, and isolation of the guests is less then optimal.

I would NOT give root access within a guest to an untrusted client.

I am sure LXC will be the way of the future, but I still consider it not ready for prime time. YMMV.

Bodhi,

How do you mean buggy? Did the host crash or what happened?

I’m considering lucid as a Host OS with LXC and I don’t want it to go down. If there are issues with the containers themselves, can you elaborate?

Thanks.

@Roberto Aloi :

I personally switched to Debian for both OpenVZ and LXC as Ubuntu has in the past been too buggy.

With Ubuntu 11.04 they were planning better support for LXC, but I have not yet tried it.

Also, LXC is in fairly rapid development, and you might get better support if you post to the LXC mailing list.

At a minimum I highly suggest you try 11.04.

@Ulli Horlacher :

You can use
sudo apt-get remove – -purge foo (two “-” in front of purge)

sudo apt-get purge foo
