How to ping between nested vm running on two different machine?

[ujjwalpawar]

Hello,

I have two vm(say vm1 and vm2), that are running vm inside them using nested virtualization (say vvm1 inside vm1 and vvm2 inside vm2). How can i ping vvm1 from vvm2 and vise versa? Currently vvm1 can ping vm1 and vm2 but not vvm2 and similarly vvm2 can ping vm1 and vm2.
