@ Raimund OS or container virtualization is a type of virtualization technique that serves certain things very well. One can use the available resources, memory, net, disk, cpu more than with any other techniques. The footprint of the server is significantly smaller than in any other case. With KVM, XEN and others the memory for example is allocated to VMs and cannot be used by other VMS. This is a very good model for Amazon EC2 and other providers since they know that they get $X for $Y investment on hardware and they can make sure that nothing is going to disrupt the use of that allocated memory. This is true for the other resources as well. So for them this model is perfect.
For me where the most important is cost reduction and green IT it is not so perfect. I want to squeeze as many servers on the hardware as many possible. The hardware has a price, running it has a price and it has a carbon footprint too. We live in an era where decreasing the carbon footprint of a running virtual machine is actually very important. Decreasing the hardware and running cost is also very important since it can mean that a certain business model is working or not. Canonical introduced container virtualization in Ubuntu Hardy and since then my company and I'm sure many others have been heavily building on it. We could switch to something else, I'm not standing in the way of a change, but I need something that provides similar features and stability. LXC is heavily being developed and I know that it is the future, but right now it can't replace OpenVZ. Not just yet. The only thing I and others are asking is to provide us with a way to run Ubuntu Lucid in OpenVZ containers, nothing more. I'm not asking that Canonical provides OpenVZ kernels in Lucid. It would be great, but I have other options, Debian, CentOS, RedHat, etc... Where I don't have options is the Lucid init sequence. This change was introduced by Canonical and made it very difficult to run their product in an OpenVZ guest. I believe Canonical has some responsibility around providing at least the ability to run their product in an OpenVZ container since they provided that feature in the previous LTS. Alternatively I can go for LXC as well if there was simple way to migrate over and there were some assurance that it is as mature. I hope that Canonical listens and steps up to do their part.
