[Qemu-devel] Is IOThread for virtio-net a good idea?

[Anton Kuchin]

As far as I can see currently IOThread offloading is used only for block 
devices and all others are emulated by main thread.

I expect that network devices can also benefit from processing in 
separate thread but I couldn't find any recent work in this direction. 
I'm going to implement a PoC but I want to ask if you know any previous 
attempts and do you know why it can be a total waste of time. Are there 
fundamental obstacles that prevent network emulation handling in IOThread?
