We can tunnel its migration data through qemu.  Of course, gathering its

immediately start running on the destination node; the guest will fault its
memory to the destination.  An advantage is that that the cpu load is
immediately transferred.

Given the potential need to develop DSM and migrating multiple VMs
simultaneously as well as few details to decide on, can the patch
series (with other review tweaks fixed) be accepted without migration
support?

Definitely.  I don't expect DSM to materialize tomorrow (or ever).
