My preference is to stick with the "standard", 32-bit RHEL3 kernel in the guest. My point in the last email was that the hugemem kernel shows a remarkable difference (it uses 3-levels of page tables right?). I was hoping that would ring a bell with someone. Adding bypass_guest_pf=0 did not improve the situation. Did you want anything particular with that setting -- like a RIP summary or a summary of exit-entry cycles? david ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
