Hi, i'm facing some performance issues with a KVM/QEMU Setup with Windows 7 guest. When Win7 is idling at 6% kvm takes in average 120% load. So i was wondering to give Virtualbox a try. Is it possible/sensible to do that in parallel?

What do you mean by in parallel? At running two different virtualization engines at the same time? That should be possible but is not advisable since only one hypervisor can use hardware accelerator of the chip sets and the other has to run in software virtualization mode.

Do it one after the other!

thanks and yes that's what i meant running both at the same time. Does it have a negative effect to have both installed at the same time?

No negative effect of having to virtualization engines installed at the same time

thanks florian, then i will try a "migration" to virtualbox. If you convert your comment to answer it can mark it correct.

Check to see if windows running the update service, once I found it to be the problem, and after killing it and disabling auto download for updates, that solved my problem.

I'm experiencing the same every time Windows Update is being active - though I don't deactivate it.
