# of VM's: 3 - two Linux guests are idle, one Windows guest is<br>
installing updates.<br>
<br>
I've installed a Windows 2008 R2 guest with virtio disk, and all the<br>
drivers from the latest virtio iso. I've also installed the spice agent<br>
drivers.<br>
<br>
Guest disk access is horribly slow, Resource monitor during Windows<br>
updates shows Disk peaking at 1MB/sec (scale never increases) and Disk<br>
Queue Length Peaking at 5 and looks to be sitting at that level 99% of<br>
the time. 113 updates in Windows has been running solidly for about 2.5<br>
hours and is at 89/113 updates complete.<br>

virtio-block or virtio-scsi?<br>
which windows guest driver version for that?<br>
<br>

I can't say my Linux guests are blisteringly fast, but updating a guest<br>
from RHEL 6.3 fresh install to 6.5 took about 25 minutes.<br>
<br>
If anyone has any ideas, please let me know - I haven't found any tuning<br>
docs for Windows guests that could explain this issue.<br>
<br>
Thanks,<br>
