When I run virt-manager on Bookworm, all it does is tell me that “xen is not connected”. There is nothing to indicate that KVM is anything that virt-manager might support, or why it currently doesn’t.
The best I can do is to make a VM in gnome boxes, use “ps” to capture its command line to qemu, re-format that into something that I can put into a bash script, and edit in additional options that Boxes/libvirt absolutely refuse to support.
Most of the host integration features are better in Virtualbox. On the other hand, with qemu I don’t have to look at VB filling the journal with ubsan errors (and wonder if its crappy driver is corrupting shit). If VB supported KVM, I would go right back to it.
You just need to add a KVM connection.

Highly doubt that, specially if you’re using Virtio devices and the qemu guest agents.
Aha, thank you! That’s just a weird enough concept to “attach to” a local QEMU user session (where virt-manager will be the guy spinning it off anyway) that I would never have seen it.
Every newbie article about virt-manager starts with a filled list of connections, so I was down to figuring that it’s cleverly detecting a missing dependency or permission and silently eliminating list entries for me.
