First, my specs
i5 10600K
16GB RAM
RTX 3060Ti for host
AMD HD 7950 for guest passthrough
Guest uses a img file stored on an NVME ssd
The problem, after a few minutes, the guest completely locks up, will not respond to any input at all, and anything connected to it times out (I use nomachine to control it)
I dont even know where to start figuring this out
the xml for the machine
