I have two options, virtio and virtio-scsi. I was using virtio, and have also attempted virtio-scsi on another Windows guest with the same results. Using the newest drivers, virtio-win-0.1-74.iso. *Steve Dainard * IT Infrastructure Manager Miovision <http://miovision.com/> | *Rethink Traffic* 519-513-2407 ex.250 877-646-8476 (toll-free) *Blog <http://miovision.com/blog> | **LinkedIn <https://www.linkedin.com/company/miovision-technologies> | Twitter <https://twitter.com/miovision> | Facebook <https://www.facebook.com/miovision>* ------------------------------ Miovision Technologies Inc. | 148 Manitou Drive, Suite 101, Kitchener, ON, Canada | N2C 1L3 This e-mail may contain information that is privileged or confidential.

I've installed a Windows 2008 R2 guest with virtio disk, and all the drivers from the latest virtio iso. I've also installed the spice agent drivers.
Guest disk access is horribly slow, Resource monitor during Windows updates shows Disk peaking at 1MB/sec (scale never increases) and Disk Queue Length Peaking at 5 and looks to be sitting at that level 99% of the time. 113 updates in Windows has been running solidly for about 2.5 hours and is at 89/113 updates complete.
virtio-block or virtio-scsi? which windows guest driver version for that?
I can't say my Linux guests are blisteringly fast, but updating a guest from RHEL 6.3 fresh install to 6.5 took about 25 minutes.
If anyone has any ideas, please let me know - I haven't found any tuning docs for Windows guests that could explain this issue.
Thanks,
