[libvirt] [PATCH 0/4 v2] ivshmem support

[Osier Yang]

v1 - v2:
  * Change attribute "model" to be a sub-element instead.

NOTE:
  Since the invshmem server socket path is not created by
QEMU, but by an external app called "ivshmem_server", It's
not good to construct the socket path in libvirt with a solid
rule, and force the user to figure out what the path is
libvirt uses first and use that for "ivshmem_server". Thus it's
the user's business to set the selinux context on the socket
path so that the qemu process could be started successfully
when selinux is enabled.

Shawn Furrow proposed a patch more than a month ago:
https://www.redhat.com/archives/libvir-list/2012-September/msg01612.html

But this is a complete different implementation. Considering
there could be other memory related devices in futuer, this
introduces a new device model, called "memory device", instead
of a specific device like "ivshmem", though only "ivshmem"
is supported currently. Please refer to PATCH 1/4 for more
details.

CC'ed to Cam and Shawn, to see if there is advise on the documents.

  conf: Parse and format memory device XML
  qemu: Add cap flag QEMU_CAPS_IVSHMEM
