Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I'm trying to virtualize any Windows OS on my AMD E-350. I enabled the hardware virtualization in the BIOS but it somehow seems to perform very poorly!

Win XP install took about 2.5h and seems kind of exhausted (slow application start, CPU utilization at nearly 100%, ~5MB/s in IO) I didn't even finish the installation of 7 since it didn't seem to perform any better.

The image format is qcow2 I'm using virtio drivers for this image as well as for the networking

I'm wondering about this since the performance was WAY(!) better on my laptop Intel CPU (which is 3yrs old)

Do you have any idea?

What program are you using to create/manage the virtual machines? –  Salem Nov 17 '12 at 15:11

It seems to be a problem with the cow2 format, raw performs at a magnitude better! Im just using commandline kvm –  user984308 Nov 17 '12 at 16:20
