EDIT: I am the biggest idiot lmfao, I wasted so much time on this. It's always the simple easy mistakes.
So...I never use KDE (much prefer GNOME, only using KDE now because with the dGPU setup GNOME is insanely unstable whenever it goes into suspend mode), so I'm not used to the dolphin file manager. It's hidden files look 95% identical to non-hidden files, and so this whole time I've been trying to create a VM from `._archlinux-2023.06.01-x86_64.iso` whatever that file is.
=============
TLDR: When I hit "begin installation" in virt-manager, it shows the tianocore logo for a split second then kicks me out to some weird shell.

Am I making a simple stupid mistake? I checked the arch wiki on PCI Passthrough, KVM, and Qemu.
The PCI Passthrough wiki says this may be due to the image not supporting UEFI, but it's the standard arch image from July which I used to install my host OS and it's definitely a UEFI setup.
Oh and weirdly, I had no issue making a windows VM about 200,000 times on this machine while I was figuring out dGPU passthrough (got it figured out ?)
SYSTEM:
Motherboard - Asus ROG z690 Extreme
CPU - i9-13900k (two monitors)
GPU - RTX 4090 (one monitor)
OS - Vanilla arch linux, installed with archinstall and selecting the KDE desktop with nVidia proprietary drivers, using x11
After trying my usual customizations, I tried with the simplest, most guaranteed setup:
- In Virt-Manager > file > new VM > local install media > select arch iso > set OS as "arch linux" > give some RAM and CPUs > give some storage > name is "archlinux" > customize before install > change firmware to UEFI (also tried UEFI x86_64: /usr/share/edk2/x64/OVMF_CODE.fd).
- Deselecting "Copy host CPU config" is a meme because when you apply it it just reverts to being selected; it does the same thing for Windows VMs.
- VirtIO disk 1 and NIC are both set to virtio.
- Pressing "Begin Installation" at this point starts up like usual, but immediately fails as described above.
I must have made hundreds of VMs on several machines a few months ago, including laptops and desktops. This is my personal home desktop and I'm not sure what I'm doing wrong but I suspect it's a simple thing I've forgotten (I hope it is).
