Hi,
I think we shouldn't save entropy inside jails, as the data is not going
to be used by rc script (pjd@126744). If there is no objections, I will

I can't really speak to the correctness of this as I don't know the Xen

Rather than have this hang directly off of nexus0, it might be better to

Please put this in a header instead of using an extern in the Xen PV code.

If you go the xenpv route, you would replace 'nexus' with 'xenpv' here.

This looks fine modulo possibly making it a xenpv child instead of a nexus
child.

Since the tests all use '!lapic_disabled' I think I would prefer to flip the
name to 'lapic_valid' and have it default to true. It would just be a
cosmetic change to the current patch, bu

This patch includes changes to xenstore in order to boot as Dom0. This
is different from booting as a guest, since when booted as Dom0
xenstore is not available. This patch sets up a memory page, an

It contains a workaround for
