vzstats in beta
nepalFor the last two weeks or so we've been working on vzstats -- a way to get some statistics about OpenVZ usage. The system consists of a server, deployed to, and clients installed onto OpenVZ machines (hardware nodes). This is currently in beta testing, with 71 servers participating at the moment. If you want to participate, read and run yum install vzstats on your OpenVZ boxes.

So far we have some interesting results. We are not sure how representative they are -- probably they aren't, much more servers are needed to participate-- but nevertheless they are interested. Let's share a few preliminary findings.

First, it looks like almost no one is using 32-bits on the host system anymore. This is reasonable and expected. Indeed, who needs system limited to 4GB of RAM nowdays?

Second, many hosts stay on latest stable RHEL6-based OpenVZ kernel. This is pretty good and above our expectations.

Third, very few run ploop-based containers. We don't understand why. Maybe we should write more about features you get from ploop, such as instant snapshots and improved live migration.
