Feature request? Auto start vm upon next shutdown

[Marc Roos]

It is not a destroy. With some hardware changes you require the host to 
shutdown down and then start. The shutdown down is manually given either 
via some acpi request or from within the guest.
When the guest is down, the 'host' recognizes this guest requires a one 
time start, and starts it. 

This should 'solve' that if you change hardware you have to wait for the 
guest to shutdown and then start the guest manually.

I would not know what level this can best be implemented.

This took me a while because at first I thought you were talking about 
the vm automatically starting on libvirt invocation (autostart), but 
instead it sounds like you want a function to allow the user upon making 
a change to initiate a hypervisor-level restart (i.e. destroy then 
start). Correct?
