[Xen-devel] [PATCH OSSTEST v2 08/18] Toolstack: Refactor guest lifecycle.

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Implement destory/create as per toolstack methods, including implementing the
libvirt version which previously didn't work. To do this we use the virsh
capability to convert an xl/xm style config file into the correct XML.

xend basically calls into the xl helper since they are compatible.

xl/x, uses ->{Command} which will eventually become private.
