Virl.0.9.280 Very high CPU usage

Hello @Ciscoguy.
With your simulation running can you collect the output of the following command and post?
top |grep -A5 'top\|kvm.real'

Also, have you already upgraded the IOSv images, and if so what version are you currently running?
We are both running a similar configuration and we have not seen the same CPU usage we saw before.

This is what I see regularly on my machine:

virl@virl:~$ cat /proc/cpuinfo  |grep 'model\|MHz\|proc' |sort |uniq && free -h
cpu MHz		: 2693.930

With 8 IOSv devices running:

virl@virl:~$ top |grep -A5 'top\|kvm.real'
