so, I'm a bit new to the aspect of virtualization on Linux, and noticed that i could pass a gpu to the VM, i went ahead and decided to try to accomplish this!
it worked...in a sense, i could start the vm with a script, but once it loaded, it just froze. i can't do anything with it, there's no console, i've even done a vnc setup and it just stays at connecting.
I had it somewhat working before but that was with PCI-Stub instead of what i am doing now, which is vfio-pci.
with PCI-Stub, it froze the qemu console but vnc would connect but it just showed a constant "Starting windows..." screen(trying to install Windows 7)
Specs:
CPU: intel core i5-4690k - linux using HD Graphics from cpu
GPU: ZOTAC AMP! Edition GTX 760 - this is the gpu being passed on
my script to launch is:
the gpu is being bound correctly at startup(at least i think it is):
im not sure if i have missed something or what? i have a monitor connected to said gpu being passed too.
I don't know if this helps solving this but my linux boot is using my IGPU on an intel 4690k. and yes, Intel_IOMMU is on
If there is any other information you need, just lemme know!
