Why will it? It will most likely just call halt a bit later.
I agree.

I don't have a problem with this patch as such, so
Acked-by: Michael S. Tsirkin <mst(a)redhat.com>
though I'm still not really sure why do we
want to block guest immediately on panic.
Why not let it call halt a bit later?
To make sure the panic is detected, and action taken, in the host even
if management has crashed at the time. For example, even if you have
reboot-on-panic active, management has time to take a core dump of the
paused guest _before_ the reboot.
