Our benchmark framework allows us to use oprofile during test...
couldn't it be better than vmstat?

I agree. Actually, I always try to use 'default' configuration or
installation but I will try to describe the tests in details.

The different configs used are available in the lxc site. You will
notice that I used a minimal config file for most of the test, but for
Openvz I had to use the one I found in the OpenVZ site because I faced
kernel build error (some CONFIG_NET... issues). I think that the
differences are more dealing with network stuff.

I already used this page. I had to increase 'diskinodes' and 'diskspace'
resources in order to run some test properly (the disk errors were more
I'm wondering why a default 'guest' creation implies some resources
restrictions? Couldn't the resources be unlimited? I understand the need
for resource management, but the default values look a little bit

For sure... I will take a look at how integrating it in our automatic
