# of VM's: 3 - two Linux guests are idle, one Windows guest is
installing updates.
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,
