Thanks, I've asked for some testing assistance from our KVM team but will note here some of the details from the original report of this problem..

repro steps are just a simple local host migration.

..they later noted that increasing the speed was a workaround:
(qemu) migrate_set_speed 1G

so you would want to test w/ default speed to confirm the issue is resolved

(qemu) migrate -d tcp:localhost:4444

using " cosmic qemu version 1:2.12+dfsg-3 " from Bug 169712 / LP 1781526 (which enables qemu to use 2MB THP backing for powerpc), plus the test kernel build from this bug.

Note without the kernel fix discussed in this bug, a migration problem might still happen even without that qemu THP patch if you got lucky enough to have a 2MB alignment by chance.
