Recently, we've been running tests and benchmarks in different
virtualization environments : openvz, vserver, vserver in a minimal context
and also Xen as a reference in the virtual machine world.

We ran the usual benchmarks, dbench, tbench, lmbench, kernerl build, on the
native kernel, on the patched kernel and in each virtualized environment.
We also did some scalability tests to see how each solution behaved. And
finally, some tests on live migration. We didn't do much on network nor on
resource management behavior.

We'd like to continue in an open way. But first, we want to make sure we
have the right tests, benchmarks, tools, versions, configuration, tuning,
etc, before publishing any results :) We have some materials already but
before proposing we would like to have your comments and advices on what we
should or shouldn't use.

Thanks for doing such a great job on lightweight containers,
