I purchased a "Coral M.2 Dual Edge TPU" to install in my Unraid Server to use with my Blue Iris Windows VM. I installed this card and can see it in my Unraid "Systems Devices" as can be seen in this image:

The two TPUs are 28 and 29 within the IOMMU group 10 with multiple other system items. The option to select the check box and pass this through to the VM is not there so I am not sure how pass it through. Any help would be appreciated. It also does not show as an option in the VM settings as shown below:

Add second image.

If they are in the same group then you cannot pass each one to a separate VM.

Did you try to edit the xml manually and passthrough the device(s)?

Should be as simple as adding to the <devices> section something like:

<hostdev mode='subsystem' type='pci' managed='yes'>

<driver name='vfio'/>

<source>

<address domain='0x0000' bus='0x28' slot='0x00' function='0x0'/>

</source>

</hostdev>

or 0x29 for the other chip.
