From cc1297789f961b9e45a9381d35e9e97e5d1e551a Mon Sep 17 00:00:00 2001 From: Martin Kulhavy Date: Fri, 4 Aug 2017 17:23:36 +0300 Subject: Automatically add the virsh IP to known hosts During the generation of the bootstrap VM, ssh connection to the host machine is opened. If the IP is not yet in the list of known hosts, the installation blocks and waits for user input. The fix queries the host and adds the ssh fingerprint(s) to the list of known hosts, if it is not present already.
