Xen devel - Apr 2009 - [PATCH] xend: fix avoidance to restart domain on crash

If a qemu-dm dies immediately (probably by wrong setting),
xend repeats to restart a domain so many times. 
That causes system overload.

There is already a logic to avoid too early restarting, however,
it might not work. Since xenstore entry
''xend/previous_restart_time''
is volatile. XendDomainInfo.destroy() which removes the entry from
xenstore is called in some places.

Also, this patch prevents too early restarting even at the first
domain creation.

This looks fine, but I''m bemused why you and Ian Jackson saw this
behaviour, and it all worked perfectly for me.

Indeed, I even coded up something very like your fix before I found the
original worked just fine for me.
