libvirt isn't just a wrapper around qemu-kvm, it drives half a dozen different virtualization systems, giving you the benefit of abstracting the details of the hypervisor from the management tools. So for that reason we don't support tweaking the qemu command line arbitrarily. However if there are particular features of qemu or KVM that you think we should support, please raise them.
1) Higher resolution. My boss gave me two big monitors that can do 1920x1200, and all I can get for my guest machines is tiny little windows with hardly any room to work inside.
2) The ability to see what options qemu-kvm was invoked with. Even if I can't change them, at least I can understand what I am getting. Right now, it's a black box to me.
Incidentally, the guest machine that I described in the first message in this thread is using the virt-blk driver, so I wonder if I'm seeing the same problem as described in the thread on the test slowdowns. I just checked, and the disk image is sparse, although there seems to be some doubt that that has anything to do with the problem.
