Thunderbolt Passthrough, using as a type 1 Hypervisor.

Title has the main portion of interest.

I have googled and cross referenced and have yet to find an answer. Setup is a bit “redundant” in what I will virtualizing.

For context I’ve have done the following in ESXi a few years ago with a MacBook Pro. Was a side project for testing. Fast forward to today and using officially supported hardware (MacPro 2013 & Mac mini 2018) and I have nothing but headaches. VMware being screwy passing through gpu but no display grabbing thunderbolt but not listed in pcie devices.

Which brings me here.

Basically would like to use either of the fore-mentioned macs to do the following:

Mac => Proxmox => MacVM

with display, thunderbolt and storage.

Context:

I have an array of thunderbolt hard drive cages that used to work up until Monterey. I used to use a custom KEXT. But that text is no longer working with anything newer than Monterey.  The arrays are formatted and using SoftRaid (win/mac) in Raid 5 and using APFS containers. I could do this in windows but there is no GPU passthrough in Workstation Pro.

So I’m at a crossroads of selling hundreds of dollars worth of equipment because it happened to use a chipset that Apple didn’t sign off on at the start of thunderbolt 3, or buy one or two more pieces of equipment that are compatible but are way overpriced to the point it overshadows my initial investment.

Basically use Proxmox as a HAL to mask the thunderbolt chipset allowing the drives to appear in macOS. I would like to use the VM as a desktop so GPU passthrough is needed along with audio.

Thank you for reading. I know there are not many Mac users out there using Proxmox and was hoping to start discussion on how I can pull this off and configured.
