[libvirt] [PATCHv2 0/2] Swap order of AddImplicitControllers and DomainDefPostParse

[Viktor Mihajlovski]

Implicit controllers may be dependent on device definitions altered
in a post-parse callback. E.g., if a console device is
defined without the target type, the type will be set in QEMU's
callback. In the case of s390, this is virtio, which requires
an implicit virtio-serial controller.

By moving the implicit controller definition after the post-parse
procssing this can be fixed. As Martin pointed out, implicit controllers
should not need post-parsing, so the rearranging should not hurt.
Probably this is only affecting the S390 virtio console anyway.

V2 Changes:
 - Promoted from RFC to Patch Series
 - Added an qemuxml2xml testcase highlighting the issue: applying the first
   patch only will fail make check as the implicit controller is missing.
