Hi
I'm desperate, i don't know why this happend, i lost one of my NVME drives in my unraid server. The good thing is that the only thing it was hosting was the iso share and a vm .img drive that only stores temporary files. So nothing lost. So i just swapped out the NVMe for a new one. Redownloaded the correct Virto driver ISO so it's the same version as before.
Created a new hdd. on this drive and now comes the issue.
I can't see it inside the OS, and the 2 other NVMe drives that i was using passthrough with stopped showing aswell.. I'm lost. I've tried reinstalling the driver pack but it doesn't help. Nothing should have changed, have no clue why the 2 passthrough drives stopps showing just because the D: drive shit the bed.

1. New drive mounted.


2. Can see that the .img is created.


3. Can see that the drive is stored on the correct drive. The size is 200GB.


4. Same driver version pack as worked this morning, can see the correct path to the new .img drive.
In the bottom you can see that it sees the 2 nvme drives i've passthroughed.
Looks just like it did when it worked before.


5. In windows it's missing the drives. A & B was the NVMe drives that was passthroughed and D: was the .img drive that crashed.

added some stuff

I've now tried everything to add a new drive just to get that to work but i'm unable to, so it feels like it's bugged? No errors in the logs and not even the passthrough work?
Could it be a driver issue? I've tried different versions but still nothing.. :(


EDIT1: I tried creating a new VM, and on that vm i have no issue adding a new drive. Then i do the exact same on the old VM and it just doesn't work..
EDIT2: Kind of solved it, tried cloning the VM. And in the new clone the passthrough and adding of a new disk works.

compared the .xml files of both and the only difference i can see is in the pci configuration.
