Wistar – virtual lab environment

This is what I was looking for a long time. Wistar is a virtual lab environment based on KVM with helps me to run any topology in a minutes.

This is simps as:

creating topology > adding some vMX / vQFX > draw connections > run the topology

After few minutes (or 10s of minutes depends on how many devices you have) you and ssh to mgmt int and start testing.
