Hmm. Reduce the number of shadow page tables (KVM_NUM_MMU_PAGES). You can also turn a few passes off in the main audit function, but that of course reduces its effectiveness. btw, the error may occur before the guest fails, so keep an eye on dmesg. Once it hits things will slow down even more due to a flood of printks. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
