I like the looks of it. I see an issue is open to include other OSes. For me that would be really critical for me to be able to make serious use of it.
I’ve not yet got the hardware to give it a go in real anger but it’s on my watch-list. One question:
Does it have similar remote functionalities like as lxd? Or better still, can it be run on a remote kvm host without needing to be installed on that host (e.g. by qemu+ssh? )
Also …imagine, a unified tool that handled both lxd containers and multipass VMs…Very convenient way to define a testing environment when pure lxd isn’t quite enough.
