Forgot about that. Think there are a few. Here is an example. https://github.com/osamuaoki/incus-ui-canonical

Edit: Here’s another. https://github.com/PenningLabs/lxconsole

I’m not sure about virt-manager, but there is Incus. I have a server coming soon that I am going to test it out on. https://github.com/lxc/incus.

This is what I use. I tried other ones, but this one is simple to set up and edit. It’s very clean and has a ton of widgets for services. I would like it to have a login option, but that isn’t a deal breaker.
