[Xen-devel] [PATCH] [RESEND] allow UUID to be set in domU config

  • To: xen-devel@xxxxxxxxxxxxxxxxxxx
  • From: "Andrew D. Ball" <aball@xxxxxxxxxx>
  • Date: Wed, 25 Jan 2006 10:24:05 -0500
  • Delivery-date: Wed, 25 Jan 2006 15:33:28 +0000
  • List-id: Xen developer discussion <xen-devel.lists.xensource.com>

Treat xenstore UUID for domU's like MAC addresses for virtual network
interfaces -- can be set by user in domU configuration, but is 
generated randomly by default.

xm-test results: 
[These are for pristine changeset 8627. I see no difference between
these and the results for changeset 8627 with this patch applied.]
