XCP-NG as a VM in Truenas

Hi , i see XCP-NG with a Trunas is a very popular option and i would like to give it a try.
I am getting a small Nuc to run XCP-NG and my old hp microserver will run freenas…
I plan for most of the vm’s to run on the internal SSD, i would also like to play with GPU passthrough.

can you run XCP-NG as a VM in trunas?
my plan is to have a replication to the nas, in case my main nuc is offline…
i also have an old nuc i will set up as a third xcpNG

Never tried but I don’t recommend doing it as it will mostly likely cause some unusual issues.
