Hello.
I started using Linux recently after getting myself a PC with 32 core CPU. Still a freshmen to most of this. I found that only this version of linux “Manjaro XFCE” woks with my PC! I tried others with nothing but problems and no boot issues!
I feel a bit comfortable with this distro., so I wanted to start using virtualisation (I need Windows 10 for some FEM/CFD work, and therefor I need to passthrough my GPU), and quickly found out that QEMU was the way to go, and I ended up following:

That got me locked out of my PC.
Format, fresh system, and follow this;

Which did not work well because the mouse was lagging when I set:
Video - to - VirtIO
The only thing that I liked is dedicating an SSD to a virtual machine!
So I wiped my system, and tryed:

Each time after I install QEMU, and after I restarted my host PC and enter the password, NOTHING happened for 5++ minutes before the desktop comes up!
I have now found this (recently 
):
[How to] Setting up QEMU/KVM with virt-manager
[[How to] Setting up QEMU/KVM with virt-manager](https://[How to] Setting up QEMU/KVM with virt-manager)
Really tired of whiping the system I want a stable life.
To make sure that I did not do something wrong, I want to diagnose my system, or just know if it is even possible to have this done at all with this system (passthrough my GPU to the virtual machine)
Can anyone with knowledge about virtual machines help me diagnose this problem!
- 5++ minutes before the desktop comes up after logging in!
- GPU passthrough does not work
Many thanks in advance

Thank you so much for sharing this 
a 6900 or a 7900, if I could find a cheap one.
