VMware VMotion and CPU Compatibility
Jul 25, 2008
This white paper focuses exclusively on CPU compatibility and outlines CPU compatibility checks performed by VMware VirtualCenter before allowing migration with VMotion. It describes why some CPU compatibility constraints make VMotion possible only between certain revisions of CPUs. The appendices detail some differences in features and extensions in current CPUs and describe procedures that could be used to relax some CPU compatibility constraints to facilitate VMotion.
