Need Help on Setting Up Hardware Passthrough on Ubuntu 3930K

I’ve gotten up to this point : “Before we do that, however, I’d like to stop and take a quick look at a few different storage options. I’m currently using pure SSD storage for my VM’s, but you may want to choose a mix of SSD and HDD” so i went back to another part of the thread here : The Pragmatic Neckbeard 2: ZFS - SSD speeds at HDD capacities and I find that I DO want ZFS for my windows emulation.

g̶i̶v̶e̶n̶ ̶u̶b̶u̶n̶t̶u̶ ̶i̶s̶n̶’̶t̶ ̶c̶o̶v̶e̶r̶e̶d̶ ̶i̶n̶ ̶t̶h̶i̶s̶ ̶t̶u̶t̶o̶r̶i̶a̶l̶ ̶s̶h̶o̶u̶l̶d̶ ̶I̶ ̶a̶b̶a̶n̶d̶o̶n̶ ̶t̶h̶e̶ ̶i̶d̶e̶a̶?̶ I found this : ZFS - Ubuntu Wiki and ran sudo apt install zfsutils
is this what you meant by raw format: “for my VM’s C:/ Drive, with a raw storage format. raw disks will give us the best performance.”

I have an SSD for boot with 186 GB free but I suspect it won’t be enough given I’m planning to pile on ALOT of games /software most notable of which Star Citizen which by itself can take up 100GB. on the side i have some 2.3T free on a 4Tera and a whole 1Tera sitting around doing nothing.

also i downloaded the virtio-win-0.1.137.iso but I’m kinda clueless as to what to do with it. I mounted it.
do i copy it’s files to a folder in /usr/share/?

thanks!
