so you can reproduce the bug ? 

One idea, with my patch,the vm config file is on source during migration and stats are done on disk with qmp during live migration.

Maybe this can cause some queues in multiplexing part ?

The whole thing is unstable now. 

Added another patch to tolerate up to 5 query-migrate failures: 

https://git.proxmox.com/?p=qemu-server.git;a=commitdiff;h=b0b756c14d58c3d84af41c7cd967cedddb32fd44 

but it is still not reliable - got arbitrary hangs.
