Like this, then, AFAICT from the docs.  FAOD, this shouldn't affect
deliberate attempts by the dom0 to reboot the host ?  I found the docs
not quite clear on this point.

Subject: [OSSTEST PATCH] ts-xen-install: Pass `noreboot' to Xen

This prevents Xen from rebooting the host, if Xen crashes.

This reboot serves no function in osstest, since a crashed host will
be automatically power cycled to recover it.  (Firstly, during log
collection, a renewed attempt to boot from the hard disk; then, during
the next test, netboot to wipe the machine to reinstall it.)

But the reboot does make logs more confusing, and we suspect that the
reboot loops which can occur (eg if the version of Xen and Linux being
tested always crashes on boot) might be implicated in our test boxes
occasionally forgetting their boot order.
