AMD announced that its facility dedicated to fine tuning, the Operating System Research Center (OSRC), has extended its focus to include Sun OpenSolaris and the xVM products.
This may imply that xVM Server may have a performance advantage when used on AMD processors.
It’s unclear if and how this new effort will impact the upcoming release 1.0 of the new Sun hypervisor, but one thing is for sure: with Intel in strong partnership with VMware, AMD has to find another strong virtualization partner to boost the sales of its finally released quad-core CPU (codename Barcellona). Maybe the chip manifacturer is betting on Sun.
