Are you using qcow2?  In some cases qcow2 will stall the guest cpu.

Note that defragmenting the guest drive may cause the qcow2 file to fragment even more, and will certainly increase its size. I recommend only defragmenting when using raw storage.

I don't think so. I created a partition on my host "real" harddrive and provided this partition to my windows guest.

If you have an idea, which virtualized drive system could be the fastest (except giving a complete disk to the guest), your comments are welcome :-)



interface: virtio
cache: none
format: raw, using a partition or logical volume

What are you using?
