Why are Apple Silicon VMs so different?
There's mature VirtIO drivers for just about everything already, under the virtio-win umbrella: https://github.com/virtio-win/kvm-guest-drivers-windows
My desktop PC is using libvirt+qemu (on an Arch host. I use Arch, btw) to PCI passthru my RTX 4090 GPU to a Windows guest. I installed the guest initially with emulated SATA for the main drive. Once Windows was up and running, I installed virtio-win and the guest is now using virtIO accelerated drivers for the network interface, main disk. I'm also sharing some filesystems using virtio-fs.

Help with my setup
So, I started configuring the PC with ubuntu desktop (since I need a GUI for my use case). Then I setup a windows KVM with this. In my use case, I want the windows VM to be always connected to a VPN (Mullvad) that has the toggle of LAN connections turned on. This is because I want to use sunshine on the KVM to stream my desktop to a firestick. This is how I have been configuring one PC till now for my family to be able to watch TV. The issue is that I cannot use sunshine or parsec cos there are no encoders in the VM, thus the performance sucks. (I could use software encoders, but I would use too much CPU for windows VM, which would make me unable to run a LLM (this was my plan) )

VirGL
Note also: it just got an experimental Windows driver!

Libvirt/virtio: Limited resolution on Windows guests
virtio-GPU for Windows for now is just a basic display driver, without any kind of acceleration, so there shouldn't be any difference between using it and QXL, which is fully emulated and in it, if necessary, you can increase the VRAM to be able to use high resolutions, as explained here. Note: this link is just from a quick search, I tried this for myself some time ago but my intention was not to increase the resolution but just to find out if it was possible to have some kind of 3D acceleration, as it happens in VirtualBox, but is not possible yet.

Why is the virt-manager display so slow?
The only sorta-responsive display tech I've found is Virt with GL (3D) enabled. And if your physical box has 4k video you can forget about going anywhere near full screen with that guest VM.

Virtiofs slower than Samba file sharing?
I suggest you open a new issue in the repository describing this, or search if there is one open reporting the same. Also, keep in mind that as an early stage it might be a good idea to avoid copying important files using this, you could end up losing data unless you do an integrity check (recently I tried installing a game on the VM in a host directory and it didn't work. I'm thinking of an alternative or going back to using VirtualBox, since the shared folders worked very well for this purpose).

Windows Server 2019 - vioscsi Warning (129) - locking up data drive
The problem was really bad with latest virtio drivers, so I downgraded to version 204, as per: https://github.com/virtio-win/kvm-guest-drivers-windows/issues/623

How to compare HDL simulation/implementation results to Matlab?
I'd probably simulate both the accelerator and the AXI wrapper. One could instantiate a risc-v core to drive the AXI bus under simulation. gem5 or qemu see the Xilinx fork with AXI support.
What are some alternatives?
