Oracle Enterprise Linux (and Oracle VM) is freely RE-distributable !
http://wiki.oracle.com/page/Unbreakable+Linux

Yes, it's free download but also free to re-distribute including copyrights and trademarks, see the EULA for more details.

And theres now a public yum server for OEL that offers a free and convenient way to install packages from the Enterprise Linux and Oracle VM installation media via a yum client.

I've just rebooted (# reboot) my MEMSET server logged back in and entered

Does this reference to 'xen-friendly' actually mean that I have finally found a true XEN VPS VM webhost provider ?

There is yet another virtualisation technology on the block !

http://www.vizzr.info/2007/04/24/kernel-virtual-machine-kvm/

kvm only run on processors that supports x86 hvm (vt/svm instructions set) whereas Xen also allows running modified operating systems on non-hvm x86 processors using a technique called paravirtualization. kvm does not support paravirtualization for cpu but may support paravirtualization for device drivers to improve I/O performance.

Proprietary vendors take note :
Xen and kvm make use of Intel-VT and AMD-V hardware virtualisation features !
