Problem with VirtIO in Windows Server 2012 r2 installation

[Godoy]

Hello, I am having difficulties installing the VirtIO drivers when I try to install Windows Server 2012 r2, I always get the message "no signed device drivers were found. Make sure that the installation media contains the correct drivers, and the click OK ".
I followed the steps of both the official proxmox guide and in several forum posts, I tried everything and I still can't get it to work.
surely it will be some very absurd mistake or I don't know, seriously if someone would know what I could try I would appreciate it.

Windows Server 2012 r2 x64
VirtIO 1.221
SCSI Controller: VirtIO SCSI
Qemu Agent: Enabled
Memory: 4gb
Processors: 2 (1 socket, 2 cores)
Hard disk: 64gb - cache: writeback - discard: enable
Network: VirtIO(paravirtualized)

Note: Qemu Agent is disabled because then it does not allow the VM to be stoped or Shutdown

Hello,

May you try an older version of VirtIO?

 

[Godoy]

Hi Moayad, I don't think that is the problem (I saw that in forums they use the last version and it works perfectly), but could I try, do I try with any version or do I try a specific version?

The windows install is very picky on the location of drivers.
You can't just set e:\ as driver location, you'll have to define the full path like e:\virtiostor\server2012\amd64\ (or something like that).

I tried again to install with version 1.217 of VirtIO, the problem when searching for the drivers persists, I have tried folder by folder and always the same error... but if I let it scan, instead of searching manually by folder, it finds these drivers (photo ).
If I install these drivers will it work the same way? And which one would help me to correctly install Windows Server 2012 r2? since it does not appear as an option

I ran into similar odd issues but can confirm no issues using the Virtio-win-0.1.215 version of the ISO
Only weird thing to note is even after running the installer on the ISO, I had to manually install the correct SPICE driver (if in use) from device manager.

 

[Godoy]

Hi, so with this version you said the WS2012r2 drivers appear? if so, I will try again.
I don't know if the use of the SPICE driver is essential for the VM to work correctly, what would be the effect of not installing it?

Correct, the auto-loading of the CD drivers was detecting normally during install for the disk drivers. The SPICE driver is only needed if you use the SPICE access from proxmox GUI for a smoother console experience, for RDP/other remote access tools I don't believe it's needed.

Thank you @bleglord

Under Windows 8.1 Virtio-win-0.1.215 work also (in the install process of the OS)


I tried the virtio-win-0.1.221 before but they gave
no signed device drivers error

Cheers,

Here to report v0.1.225-2 is still broken. v0.1.215-2 /viostor/2k12R2/amd64 worked for me as well.

You need to use this version for 2012
