This seems very cool and I will probably try it, but I think I’m missing something. I run Proxmox so that I can have multiple VMs running on my NUC. This doesn’t really solve that right? I cant spin up a windows 11 vm one weekend for a random experiment.
Incus is roughly a frontend for qemu, so you can launch an empty VM and use the ISO to install the OS. You don't have to use a preconfigured base image.
VM support has been there for quite a while now and works nicely. I think that's what they're referring to. It started out with only system containers and then gained support for VMs and now there's work to support launching OCI images directly.
