Proxmox is a virtualization platform based on Debian. It’s not supposed to have a GUI, the management is either done via web UI or SSH. But since it basically is just Debian with some more stuff, I installed Plasma on top of it. It is also not supposed to use WiFi since that won’t work with Linux bridges. But, after removing the adapter from /etc/network/interfaces (which gets automatically added any time I make a change through PVE web UI) and rebooting, I was able to make use of the adapter inside Plasma. And also create a bridge on proxmox, add IP to it, enable IP routing, and NAT everything coming from that subnet (used for VMs) through the WiFi adapter. I just wish the noVNC could dynamically resize VM display like with VirtualBox after installing guest additions. There is no use case. It can be done, that’s it. I also tried to install Proxmox on my phone under Limbo PC emulator (QEMU-based), but I couldn’t avoid random kernel panics during installation. Also, Proxmox with 10GiB of available RAM (8+4, 2 for GPU), where the host uses up 3GiB is not really ideal. And on a weak dual-core CPU, on top of that. Edit: But now I got an idea. Now, there are issues. The simple solution will create multiple SSH connections that will never leave the laptop - that is - useless encryption, aside from other likely issues. The main thing is extremely easy set-up. OK. Thing 0: Exchange and authorize SSH keys between host and VMs. Thing 1: Create another ext4 or whatever volume on LVM, and mount it on host (probably better to have VM with large disk - why should every VM have SSH access to host). This will be used for file sharing. Thing 2: Mount it on all desired VMs using SSHFS. Thing 3: Install waypipe (like ssh -X, but for Wayland) to VMs and host. Thing 4: Create shortcuts on host desktop for desired GUI applications (which will run on VMs), prefixed by waypipe command. E.g.: waypipe -c none ssh user@debian-main.home.arpa firefox. Waypipe works with vsock as well, which might be useful in this situation, but I have no idea how that’s used, and if it is relevant here. Based on the man page, it does sound like it though. But anyway, mostly just a concept.
