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=b03a4...
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?
I would assume no one is actively working on it since it is 4 years since
that quoted message. If you wish to try to implement it, we'll review any
patches.

Daniel
