A first round about virtualisation benchmarks can be found here:
These benchmarks run with vanilla kernels and the patched versions of
well know virtualisation solutions: VServer and OpenVZ. Some benchs also
run inside the virtual 'guest' but we ran into trouble trying to run
some of them... probably virtual 'guest' configuration issues... we will
trying to fix them...
The metacluster migration solution (formely a Meiosys company produt)
was added as it seems that the checkpoint/restart topic is close to the
virtualisation's one (OpenVZ now provides a checkpoint/restart
For the moment, benchmarks only ran on xeon platform but we expect more
architecture soon. Besides the 'classic' benchs used, more network
oriented benchs will be added. Netpipe between two virtual 'guests' for
example. We hope we will be able to provide results concerning the
virtual 'guest' scalability, running several 'guest' at the same time.
