I want to convert from my Hardware build to total virtual. I have the VM up and running, it boots with my old config. I am down to three drives because I guess the GUID of the drive has changed. I notice there are other people running virtual with large numbers of drives, what do I do here? I have my pro key still and my original flash drive but VT-D passthrough refuses to work for USB, my other cards pass through fine.

The GUID of the flash should not change. Im running EXSI and have a pro key to it. I boot using the prebuilt exsi build but I also kept the flash name as UNRAID since it then uses the license file on that device and config files from there too. I did not have to set bypass to the USB key, I only assigned it in exsi settings to the unraid vm.

Did you by any chance change the label of the flash drive?  As reefcrazed noted, it still has to be "UNRAID".

 

You can't set ESXi to boot from the flash drive, so you have to boot from an ESXi build (there are pre-built ones available in the forum), but as long as UnRAID "sees" a flash device labeled UNRAID with the correct GUID everything works just fine.

 

Note that the flash drive doesn't even have to be bootable in this config -- it just needs the right label with your Pro.key in the right place.    I think everyone keeps it in its stock, bootable condition, however, so you can easily boot to "bare metal" UnRAID if you want to (by simply booting to the UnRAID flash drive instead of the ESXi one).
