LXC 1.0 Released

LXC 1.0 was released yesterday.

LXC 1.0 is the first production ready release of LXC and it comes with a commitment from upstream to maintain it until at least Ubuntu 14.04 LTS reaches end of life in April 2019. That's slightly over 5 years of support!

Tons of changes, but the most interesting for most of us here is probably support for fully unprivileged containers, which should open the door for hosts to at least begin thinking about actually selling LXC-based VPSes.  In a way, LXC is the spiritual successor to OpenVZ - after all, a lot of features used by LXC got their start in OpenVZ (PID and network namespaces, memory controller, and checkpoint-restore come to mind).

So, with that, what do you guys think?  Is LXC the wave of the future in VPS hosting?  Will it overtake OpenVZ?  Where does Docker fit into this?1   Or is containerization going to disappear completely, with KVM continuing it's upward trend?2

1: Docker uses LXC too, but it doesn't really provide a full OS environment and is designed for containerizing specific applications.  Would Docker be suitable for, say, a hosted app service like AppFog?  Or, with the introduction of fully unprivileged containers, will Docker expand it's functionality to allow a full OS environment?

2: Is KVM really on an upward trend? I see more and more KVM providers now than I did a year ago, but maybe I'm not looking in the right places.

Not sure I can see any advantage of LXC over OpenVZ at the moment.  Do you think there is?

KVM is sure popular; however I can see a resurgence in XEN coming.

The biggest advantage that I see in LXC is that all of the features it uses are in the mainline kernel. OpenVZ on the other hand... well, here's the diffstat of the official OpenVZ patch for 2.6.32:

Does LXC support live migration yet?

I think that more people would use it if they know that LXC is supporting resource limits.

One of the reasons why a lot of people choosed OpenVZ.

The other reason is the support of SolusVM.

Cloudmin does support LXC but SolusVM does not even mind.

You have to be able to easily sell your stuff and the mainstream solution is SolusVM.

KVM (like XEN) currently benefit from the lack of current OpenVZ kernels.

KVM was about running Windows but is now known for running BSD and current linux kernels (and for the better dedicated resource allocation).

I search for a panel which can work with LXC but did not find one. I will now try Cloudmin.

Rallias had done some work on an LXC module for Feathur. It's pretty easy to make Feathur modules and assuming there's a good control interface API (like vzctl for OpenVZ) for LXC it shouldn't be that hard.

LXC web panel does not work for LXC 1.0, that panel is for versions below 0.9. Lets hope they update it soon.

I heard LXC has less features then OpenVZ and less settings where you can limit containers etc.. so its basically a step back.
