“the paravirtualization techniques will be outperformed with hardware” …

Uhm, No. it’s that simple. Hardware virtualization is used to allow you to trap software operations that you need to emulate. AFAIK, it doesn’t matter how good the hardware virtualization is, if it is being compared against the paravirtual guys who come along, rip out code that has to be emulated and replace it with code the co-operates with the hypervisor. Hardware virtualization is like putting a “better” suspension in your car so it can go over speed bumps faster. The paravirt guys just remove the speed bumps.

Thanks!

The model is Back-UPS RS 1000. There\’s also a suffix \”IN\” which says it\’s a model for India, I think..

Oracle, Sun, Novell all use virtualization based on Xen. Amazon’s EC2 cloud uses Redhat and Xen. KVM is too immature and won’t catch up to Xen now, if it ever does.

“But one drawback [of KVM] is that it does not work on CPUs that dont have hardware virtualization support”
THis is the biggest issue for me!
