Passing though HBA card in hyperV causes VM to not boot

Hi all
Im trying to pass though a HBA card for a tape drive to a VM
I have found instructions online on how to do it
https://devblogs.microsoft.com/scripting/passing-through-devices-to-hyper-v-vms-by-using-discrete-device-assignment

(plus other tutorials with the same steps)
and I have from what I can tell, successfully added the card to the VM

However when I go to boot the VM I get an error saying
"The VM failed to start as that virtual machine has one or more devices assigned to it"

What does this error mean?
I know its got a device assigned to it, I just did it, but why does it stop the machine from booting?

I looked in the error logs and found ID 19560 but that doesnt show anything on google.
If I remove the card using the instructions, then the machine boots fine

Any ideas on whats going on?

Running server 2019 on both the host and the VM
Many thanks

Im not doing a GPU so not sure how much of that is relevant to the HBA card
I havnt done any of the memory stuff at the start of the instructions as that looks like its more for the GPU cards

The rest i have already followed from what I can tell

The only thing on there would be the MIMO troubleshooting, but no idea if that would help with the error im having?

Hi,

Please check the Hyper-V log in Event viewer, Event viewer>Applications and Services Logs>Microsoft>Windows>Hyper-V-VMMS and Hyper-V-VMWorker, check if there's any detailed information about the issue.

Thanks for your time!
Best Regards,
Anne

Hi,

After some research, I didn't find deep information about the issue, in order to get better help, I would suggest you open a case with MS for deep troubleshooting.

Below is the link to open a case with MS:
