Resizing RAMBlocks on the source *while* migrating is indeed problematic 
(and on the destination during actual postcopy phase) - I shared patches 
last year that abort migration in case we ever run into that issue, 
still have to follow up on that.

But to run into that here, I guess we would have to start migration 
before the BIOS comes up such that we actually resize on the source 
while migration is active.
