The blk-iopoll infrastructure is enabled system-wide by default:
kernel.blk_iopoll = 1
It can be disabled to always use interrupt-driven mode (useful for comparison):
kernel.blk_iopoll = 0

I am not yet 100% happy with this patch which aims to reduce guest CPU
consumption related to vblk->lock contention. Although this patch reduces

No, that would lead to a race condition be

Read the code. There is the kernel vhost code and the QEMU vhost
userspace code to look at. By studying both sides you can fi

In order to understand net.c it will be necessary to read other code
too. Make sure you have an environment that mak

you'll get more helpful feedback.
