The last time I checked, RHEL and SUSE were available for *purchase*, not given away.<BR/>Or is this referring to having free *hosted* virtualization, as opposed to bare-metal? If so, VMware are already doing this with their VMware Server product.<BR/><BR/>- Intel supports it for free in Intel-VT chips<BR/>- AMD supports for free in their Pacifica chips<BR/><BR/>They also support SSL3 which, like VT and Pacifica, is useless without software that supports it.<BR/>Hardware support is not a panacea and is not always faster than software. (just ask Intel how well their hardware-based x-86 emulation ran on Itanium....) <BR/>At the moment hardware virtualization support only works for the CPU. Any i/o incurs a massive overhead which, in real world workloads, generally makes it slower than a software based hypervisor.<BR/>That will likely change in the future but, at the moment, software is the way to go.Anonymousnoreply@blogger.com
