This week’s TechMail is Gain fine control in OpenVZ with resource management which discusses how to setup and manipulate resource management in OpenVZ. As with any other virtualization solution, OpenVZ allows you to assign resources to your containers so they cannot exceed them and consume inappropriate amounts of memory, CPU, or hard drive space.

Create an OpenVZ container
This week’s TechMail is Create an OpenVZ container which discusses how to create your own OpenVZ container using pre-built templates. I’ve really fallen in love with OpenVZ; I find it much simpler and much faster than VMware or other full virtualization solutions. It’s a real shame that it doesn’t work with SELinux and that the OpenVZ kernel as provided by the OpenVZ folks doesn’t even have SELinux built-in so one can’t even try to make the two play nice together.
Install OpenVZ on CentOS to create a virtual container
This week’s TechMail is Install OpenVZ on CentOS to create a virtual container which discusses using the OpenVZ virtualization software. I have to admit, I’ve become extremely fond of OpenVZ. I stumbled upon it as the open source version of Virtuozzo which is used by a lot of VPS providers and I completely understand why. All I really need or want (for the most part) is a glorified chroot or BSD jail and OpenVZ fills this really nicely, without the overhead of full hardware virtualization. It’s easy to use, easy to maintain and run, and for Linux-on-Linux virtualization I think it blows away everything else I’ve tried for remote servers (vmware server? no thanks!). The fact that it’s very light-weight and very configurable have given this thing a permanent place on my internal server. I just wish it more closely followed the upstream kernel releases, but other than that, I’m loving it.
