A little background. I daily drive Manjaro mainly because when I got a desktop in 2019 for the first time in a decade it seemed like the easiest noob friendly distro that made GPU passthrough relatively painless. I hate windows, but need it or MacOS to run CAD software for my work (mostly freelance). So now I am running an old Xeon E5-2690v3 12 core 24 thread with 64GB of ECC ram and 2 GPUs one for my desktop and one for the windows 10VM. It works pretty well.
However now I am travelling a bit again for work and have a similar setup on my laptop (AMD 5800H with Nvidia dGPU), but keeping everything synce between the desktop and the laptop is a pain and transfer are cludgy. I have a VPN to my netowrk setup which works, but RDP has been iffy on the desktop manjaro host. I have a proxmox server / NAS which seems easy and makes remote access a breeze. Is there any reason not to throw a PCIe Nvme card on my desktop, migrate my windows VM, reinstall or migrate my manjaro setup and just pass a card to each while running the proxmox host GPUless/headless with evdev for keybord and mouse? INstead of a KVM i have just been switching inputs on monitors currently which works fine for the desktop setup.
What am I missing?
I just tested the console on my current proxmox server and it seems easy to log into the web UI of proxmox from a VM hosted on the proxmox server (it is funny, you can actually get a infinite mirror situation going if you log into the console of a gui VM and then log into the proxmox server and launch the same VM console).
