[Xen-devel] [PATCH 05/18] tools/libxl: Add xenstore and console backend domain IDs to config

[Daniel De Graaf <dgdegra@xxxxxxxxxxxxx>]

This changes the event channels set up in the start_info structure of
newly built domains to be associated with a domain other than dom0,
to support xenstored or xenconsoled running in stub domains.
