I run a Windows 11 VM on xcp-ng to do testing and Windows specific graphic and video work. I use an old R9 390 in passthrough mode right now but it's running out of steam.
I'm particularly interested in the A380 series of gpus as they have a lot of the modern compute and video encoding features for around $100.
Before I pull the trigger I just wanted to know if anyone has had much experience with ARC GPUs in a VM passthrough scenario. I see in their official docs that resizable BAR is a requirement and I didn't know whether that is handled properly in a virtual environment or on XCP-NG specifically.
Any experience you're willing to share would be most appreciated.
Thanks!
I'm banking on continued driver improvements and hopefully some big price drops when the B series of ARC finally launches.
I also like the idea that the A380 it doesn't require pcie power cables. You could theoretically add one to an appropriately large 2nd pcie slot as a second GPU in a server or a workstation.
That's pretty exciting, for sure. Given that you can get single slot coolers for the half height variant makes it incredibly versatile. Hopefully that trend continues.
