VM consumes 100% of one CPU even if guest bootloader only is started

Description

On my Windows Vista 32 VM starts consuming 100% of one CPU core (Intel dual core proc) as soon as guest is started even if I breaks guest booting in bootloader (GRUB). I tried with different OS types selection, old (created in previous versios) and new virtual machines, disabled audio, USB and network - all without result. As it is not guest OS but bootloader specific, I filed it as separated bug.

Further tests show that after guest system boot CPU consuming became low but it increased to 100% after host system hibernating.

I have the same issue with virtualbox 3.1.4 on ubuntu 8.04 and 10.04. It start to load cpu up to 100-120% and then in 3-5 minutes xorg kicks me off to session login window. Everything worked better with 2x versions. Now I can't install windows XP, it crashed to blue screen. I'm using Athlon 5600+ windsor

 message log attached.

  • Status changed from new to closed
  • Resolution set to invalid

So far I saw absolutely no evidence that this is a VirtualBox bug - grub uses busy waiting since the BIOS functions have no support for waiting for some event, and thus VirtualBox correctly translates into a completely busy CPU.
