[pve-devel] [PATCH manager 7/7] ui: qemu: set correct disabled state for start button

[Stefan Reiter <s.reiter@proxmox.com>]

If a guest's QEMU process is 'running', but QMP says 'shutdown' or
'prelaunch', the VM is ready to be booted anew, so we can show the
button.

The 'shutdown' button is intentionally not touched, as we always want to
give the user the ability to 'stop' a VM (and thus kill any potentially
leftover processes).
