Hi,
I also looking for light weight virtualization solutions.
OpenVZ seems very good, but only reason that stopped me is that openvz 
kernel is not officially supported by CentOS\RHEL.

What could you say about stability of OpenVZ ?

Afaik, OpenVZ kernel is based on RHEL/CentOS kernel, but what the 
difference between them?
Is any RHEL stability patches also included in OpenVZ kernel ?

Thanks!
