[Qemu-devel] [PATCH v18 4/9] tests: add a unit test for the vmgenid device. |

* test that guest can read GUID provided on CLI from buffer
accessing it at HPA which is available via 'vmgid-addr'
property when device is inintialized.
* test setting GUID at runtime and check that it's updated
at expected HPA.
