A top drawer on the secondary monitor showing every libvirt machine: its
state, live statistics while it runs, the actions that make sense in that
state, and the snapshot list. SUPER+v toggles it over IPC.
This replaces the menu half of rofi-qemu.sh, which is still in ~/bin but
no longer bound. A dmenu row can only ever be a string, so the script
could not show what a machine is actually doing, and the snapshots it
could create were never listed anywhere.
Everything shells out to virsh, the same commands the script used, so
there is no libvirt binding and no new dependency. State changes arrive
by `virsh event --all --loop` rather than polling, which means a machine
started from virt-manager or the CLI updates the drawer too. Statistics
do need a 2 second timer, but it only runs while the drawer is open.
Memory, filesystem usage and the address come from qemu-guest-agent, so
they are absent for the first seconds after boot and on any machine
without the agent. Those rows show a dash rather than falling back to
libvirt's own figures: balloon.current is memory allocated rather than
used and reads full forever, and block.allocation is qcow2 growth on the
host rather than usage inside the guest. Either would be quietly wrong.
Destructive actions are gated, which the rofi version did not do at all:
Delete VM requires the name typed, since it runs undefine with
--remove-all-storage and erases the disk image, and reset, force stop,
snapshot revert and snapshot delete each take a confirmation click.
