ESXi

In my lab environment I have created a ESXi template VM to use for cloning nested ESXi hosts,

I ran into a challenge regarding re-generating the SSH fingerprints. I need all the nested ESXi's to have different SSH fingerprints.

IOs there a way to make the ESXi automatically re-generate them at boot?

There are tons of documentation regarding nested  esxi on William Lam blog : http://www.virtuallyghetto.com/
