[libvirt] [PATCH v2 00/11] Qemu: s390: Cpu Model Support

[Jason J. Herne]

This patch set enables cpu model support for s390. The user can now set exact
cpu models, query supported models via virsh domcapabilities, and use host-model
and host-passthrough modes. The end result is that migration is safer because
Qemu will perform runnability checking on the destination host and quit with an
error if the guest's cpu model is not supported.   

Note: Some test data has been separated from corresponding test case updates for
ease of review.

Changelog
---------

[v2]
* Added s390x cpu and capabilities tests
* Added cpu feature syntax tests
* Dropped patch: Warn when migrating host-passthrough
* Added patch: Document migrating host-passthrough is dangerous

s390: Cpu driver support for update and compare
 - Compare: Added comment explaining why s390 bypasses the cpuCompare operation
 - Update: Added error message explaining minimum match mode is not supported

 - Update: Use virCPUDefUpdateFeature to update/create user requested features
 - Other minor fixes
