[question]qemu: any plan to support ivshmem-plain migration?

[Wangxin (Alexander, Cloud Infrastructure Service Product Dept.)]

Hi, Martin

Ivshmem-plain device support property role with 'master'(master=on) or 'peer'(master=off, default mode), which controls
to copy the shared memory on migration to the destination host or not.
https://git.qemu.org/?p=qemu.git;a=blob;f=docs/system/ivshmem.rst;h=b03a48afa3ae7258bbe43490180fc5732b1f6c8c;hb=HEAD

And libvirt does not support to configure 'role' yet, see msg
https://www.redhat.com/archives/libvir-list/2016-August/msg00591.html

Qemu use 'master=off' as ivshmem-plain default property, the guest create by libvirt api can't be migrated now.

Do you have an plan to support the property 'role' and ivshmem-palin migration?

Xin
