[Users] Run once for windows xp vm very slow: correct?

Hello, I have a windows XP vm on f18 oVirt all-in-one and rpm from nightly repo 3.2.0-1.20130123.git2ad65d0. disk and nic are VirtIO. When I run it normally (spice) I almost immediately get the icon to open spice connection and the status of VM becomes Powering Up. And in spice window I can see the boot process, that completes in less than 2 minutes When I select Run once it remains for about 10 minutes in executing phase: see this image for timings comparison: https://docs.google.com/file/d/0BwoPbcrMv8mvb3FIeHExVHFibms/edit and in vm line, the status appears as down, so that I don't get the icon to connect to console. Only when it completes after 10 minutes, I get console link and I find the VM already at its final desktop prompt Is this expected or should I send anything to debug/investigate?
