SCSI or Virtio Driver Issue: Windows Server 2008 R2 64 Bit

[mstng_67]

I'm having trouble adding a SCSI or Virtio disk to a Windows Server 2008 R2 64 bit guest. The device shows as unknown in the device manager. Windows cannot locate a driver for the controller and; therefore, does not know what to do with it. Any suggestions?

Many thanks in advance.

For Virtio, are you following the wiki instructions? http://pve.proxmox.com/wiki/Paravirtualized_Block_Drivers_for_Windows
You have to download the virtio-win-1.1.16.iso from fedora site (http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/bin/) and add the iso as a cd-rom to your Win2008r2 vm, and when Win asks for drivers, point it to Wlh direcotry of the cd/iso.

mmenaz,

I had found a forum post referring to the ISO from the Fedora Project and was able to get this issue resolved. However, I wasn't aware of that particular wiki article. Looks like a good read. Thank you very much for your help. The community support here is better than many pay-for support products! I'll mark this problem "solved."

Very best regards.

Sorry to bring up a somewhat old thread, but my question is related: is Windows 2008r2 able to use PVE/KVM SCSI disks?

I can mount IDE disks.
I know the trick for virtio, but SCSI?
Strangely enough, Windows 2008 NOT r2 can use SCSI disks on the same PVE host!


I should be running the latest update already (2011-march-3):

use ide or virtio, we never test scsi for windows guests.

How Did you solved the problem of "signed driver" for 64bit systems?

Re: SCSI or Virtio Driver Issue: Windows Server 2008 R2 64 Bit [SOLVED]

the virtio drivers provided by the Fedora project are signed, so no issue with 64-bit windows.

Good. Fast Reply..
I'll try them into a VPS that heavy use SQL and IIS cache.

Now there are:

virtio-win-0.1-mm34.iso 15-Jun-2011 18:02 40M virtio-win-1.1.16.vfd 15-Jun-2011 18:02 1.4M

Manually edit the vm config file:
/etc/qemu-server/xxx.conf

Replace "virtio:" with "ide:"

refresh the proxmox web ui page to validate the conf.
stop then start the vm (not restart).

Is it Virtio stable for c:?

Dunno for the latest version.
For previous version (as of january 2011): ok for disk (for me), but for network under load it stops responding once per week or more.
