VirtualBox 3.1.2 using 90+% of cpu while idle?
 

I've noticed that since upgrading to 3.1.2 that VirtualBox ramps up to 90% and over of cpu usage. It's kind of wierd, because it's only on one core that its doing it on. My host system is Slack64 13.0 and I'm running the same os as a guest. When I run top on the guest, there is hardly anything using about 5%. Is anyone else noticing this?

i have a very similar setup:

HOST:
slackware 13.0 amd 64 dual core 1.9GHz

GUEST:
slackware 12.2 amd 32 single core


Host running virtual box 3.1.2, and idles at 7% average on both cores, but shot up to 90% while the VM is booting. Then back to 7%.

Guest idles (from top) at 2%


Maybe top reports it wrong that works natively but not virtually.

See, that's the wierd thing. The guest os is always idling very low. The host is the one where it will idle at about 1% for a while and then shoot up to 90+% for no reason. Maybe I'll try reinstalling and see if that fixes it.

edit: Seems that reinstalling VirtualBox did the trick. I have no idea why it was doing that, but now it's stopped.
