Description Juan Quintela 2015-12-16 07:56:37 EST
Backport multiple FD's work described at:

http://wiki.qemu.org/Features/Migration-Multiple-fds
Comment 2 Hai Huang 2015-12-16 08:27:17 EST
This feature provides multi-threaded (i.e. multiple fd's) 
live migration support in qemu. 

Currently, the CPU is the bottleneck with high performance 
networks (e.g. 10Gigabit or higher). This feature addresses
the CPU bottleneck by performing some operations in parallel
threads.

Please see the QEMU feature page for more info.
