Hi Andreas,
Thanks for the patches. I suppose I should insert it in my ivshmem
series, since the second patch requires it.

Note that it launches two instances, as sharing memory is the purpose
of Nahanni/ivshmem.

Add 4 ivshmem tests:
- single qemu instance and basic IO
- pair of instances, check memory sharing
- pair of instances with server, and MSIX
- hot plug/unplug
A temporary shm is created as well as a directory to place server
socket, both should be clear on exit and abort.

Hello,
I have my own virtual machine (already asked some questions about that
here).
I also have my own gmac model. I am building qemu (version 2.4.0.1) for
32 and 64 linux hosts.
The problem is with 64 bit binary. If I run as guest under qemu linux, I
could not even ping my machine.
In 32 bit
Introduce a parameter, named "reserve-label-data", which indicates
that QEMU does not reserve any region on the backend memory to
support label data, instead, it will build a readonly label data
in memory which has a active namespace containing whole backend
memory
This is useful for the users who
