why system showing double vhost-2473? I have installed KVM and created a Guest machine with two interfaces on the Ubuntu-14.04 server. When I keep running the Guest machine, the Host machine showing two vhost-2473 in the $ top command that consuming extra %CPU and %memory. Anyone can explain it why? Attached picture. N.B: I used two bridge networks in this task.

I think there is not much to explain here as Vhost Architecture by Stefan Hajnoczi covers it so well.
TL;DR:
"vhost ... creates a kernel thread ... to handle I/O events and
perform the device emulation."
And the number of devices defines the number of worker threads.
So I have usually one, and if I add two more vhost network interfaces I have three then.
