Now you can just start another monitor connection to qemu :-)
Previously I've used a multiplexing script which accepts multiple
monitor connections, and passes the commands to the real connection.
It's not ideal because a slow command blocks any others, but it
basically works.

Same here, except not just for testing: I need to use different qemu
binaries for production use, because newer ones don't work with some
VM images that work on older ones.

A decent VNC client gets close to this. If the qemus advertised
themselves, some VNC clients would show a list of them automatically.
As it is, I use Gnome's VNC client with a bookmark for each VM, which
works quite well. It even has tabs :-)

networking is often a mess, and what libvirt does isn't always what
you want, even if it often is. I need the option to set up networking
separately and have libvirt use what it's given, otherwise I cannot use it.
