If I understood correctly this would be just to be more robust against malicious guests that could try to create unkillable tight loops in host kernel mode with -smp > 1. Not sure if timings would allow it though. With numa archs if the guest cpu is lucky and has the pte in its direct connected ram, and the walker cpu instead need to access it remotely, such starvation could probably materialize. ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
