I currently have Ubuntu 19.04 (Kernel V: 5.0.0-38-generic) as the Host and Windows 10 running as a Guest in a QEMU/KVM virtual machine with UEFI capability. It’s setup with GPU pass-through, Scream Audio, and Looking Glass. This has been running mostly flawlessly.
The system hardware is as follows:
ASUS PRIME X399-A
4x8GB G.Skill Ripjaws 2400MHz
2x AMD Sapphire Tri-X R9 290X’s
SAMSUNG 960PRO 1TB
BROADCOM BCM57810 dual port SFP+ (one for Host & Guest)
I bought the GPU’s back in 2015 for $290 (interesting coincidence) each and I’ve thought about upgrading them several times. I’m not a gamer but I do like contributing the extra power to BOINC or (if I can make it work on GNU/Linux) [email protected]
I’ve been told not all GPUs play friendly with pass-through so I’m asking what modern high-end desktop GPU’s have you had good stability with using QEMU/KVM and Looking Glass?
I’d like to stick with AMD GPU’s. It’s just a general preference. I’d also like to avoid having to implement the NVIDIA error code 43 workaround.
Budget wise I’m looking for something with more compute performance than the R9 290X but I’d like to keep the total cost <$1,000. Maybe $1,200 if there’s a compelling deal going on.
All suggestions are appreciated. I plan to watercool the cards as well so there needs to be a waterblock available on the market that fits.
