I have a WinXP Pro 32bit VM with virtio drivers and it runs just fine. I don't watch the load on it, so I don't know if its CPU goes idle. I'll have to take a peek at it next week.
I have XP, 2003 and Win7 with virtio drivers, and the CPU does go idle on all of them when Windows is doing nothing. However, Windows is often not doing nothing; make sure that you have volume indexing, for example, turned off.
