Hello QEMU developers,

I’m encountering a migration failure when trying to live-migrate a VM
from a newer host (kernel 6.12 + QEMU 9.2.4) to an older one (kernel
6.1 + QEMU 8.2.10).

This is just to note - both 9.2.x and 8.2.x series are end-of-line now
from the qemu PoV, there are no further releases planned.

It'd be nice to find out what's going on here anyway.  Maybe you can
patch this on your side.

Thanks,
