Proxmox on Laptop, Network Setup - eviltoast

I am trying to install and setup proxmox on laptop and use it as daily driver. I want to make network setup that can use both ethernet and WiFi, whichever is available and i want VMs to be able to access LAN because some things dont work otherwise (like NDI). I have writen config file that makes 2 bridges and every VM would have 2 interfaces. I havent installed Proxmox yet because i dont want to mess things up (it wouldn’t be first time :) ). My question is does this config look ok and are there some recomendations.

/etc/network/interfaces

auto lo
iface lo inet loopback

# Ethernet interface
auto eth0
iface eth0 inet manual

# WiFi interface
auto wlan0
iface wlan0 inet manual

# Ethernet bridge
auto vmbr0
iface vmbr0 inet dhcp
    bridge_ports eth0
    bridge_stp off
    bridge_fd 0

# WiFi bridge
auto vmbr1
iface vmbr1 inet dhcp
    bridge_ports wlan0
    bridge_stp off
    bridge_fd 0

    Have you thought about trying QubesOS instead, as it’s pretty much built for this purpose?

      That’s interesting, haven’t considered that. Although I would want to run most things in CTs/LXCs and not full VMs for performance reasons. And Proxmox has more DIY feel which i kind of like. If I fail with Proxmox, might give QubesOS a try.

        Qubes OS doesn’t have GPU acceleration using Virtio-powered interfaces if that’s something you need. Also it’s based on Xen and you are not encouraged to mess around with dom0.

        TBH if there’s a way that you can attach to the display output of a VM with a GUI when you start your computer, it will probably fit your use-case perfectly. I haven’t found a method to do this but I think there should be some way to attach directly to the display of a VM after booting up.
