[SOLVED] W2008R2 Unkown Device

[bensode]

I've been a busy poster here and thanks for all the help and tips thusfar I've been able to correctly get all of the VirtIO drivers working on 2012R2 but am still finding that there is one unknown device within W2008R2 that I've been unable to identify.

I have the VirtIO drivers installed for storage, network and baloon. There is still an Unknown device that I've not been able to identify that IDs itself as an ACPI/QEMUVGID. Any ideas?

do you have enable qemu agent in vm options ? this need virtio-serial driver.

you can try to simple add a driver, and choose autosearch on root of virtio cdrom, it should auto find it.

this is most likely the vm generation id
see https://docs.microsoft.com/en-us/windows/desktop/hyperv_v2/virtual-machine-generation-identifier

also see https://pve.proxmox.com/pve-docs/chapter-qm.html#_vm_generation_id
You can also delete it (see link) but it does no harm and is normally even useful & wanted for backup restore or snapshot rollback.

Yep that's it. Also noticed I was viewing hidden objects once I turned that off in the Device Manager display it was gone.

Hi, I have exactly the same problem, with the Windows Server 2008 R2 and the unknown device (ACPI\QEMUGID) that I can't solve.

@bensode how did you solve it?

Best regards

This looks not like a real issue. As you run really old OS like windows 2008r2, you got some not supported features and missing/bad driver support in future.

I would Just ignore it.

.. if anyone needs to get rid of those unknown devices --- I finally tracked down proper cab files x64 and x86 that needs to be installed on guest Windows VMs. Email me if you wish direct download links...
