QEMU added support for ivshmem-plain and ivshmem-doorbell. Those are reworked varians of legacy ivshmem that are compatible from the guest POV, but not from host's POV and have sane specification and handling. Details about the newer device type can be found in qemu's commit 5400c02b90bb: http://git.qemu.org/?p=qemu.git;a=commit;h=5400c02b90bb Signed-off-by: Martin Kletzander <mkletzan@redhat.com>
