I've tested this with Karmic+KVM+ext4 and the problem is present as well. Using Karmic+KVM+ext3 resulted in the same performance boost as on Lucid.

I'd be nice if others could comment on whether this problem is present with Lucid/Karmic+Xen+ext4 too. I guess it should be, because the problem seems to be between the default cache=writethrough policy and an ext4 host OS filesystem. And changing either of them solves the issue.

Btw. I was using in Lucid qemu-kvm-0.12.3 and in Karmic qemu-kvm-0.11.0. Probably this is not important in this bug.
