How long do the creation commands appear to hang before timing out? With the
new timeouts it ought to be at least a minute, which ought to be plenty of
time to create a dozen domains.

Perhaps we need a single polling daemon that can demux kb/mouse events to
all qemu instances in a way that can be select()ed on. That would avoid
unscalable polling overheads.
