Fresh install of OL r8u3 under vbox. Installation went fine other than needing to touch up a few network items - seems that the configuration of one of the NICS (a bridged adapter to Vbox) during the installation didn't "take" and I had to use nmcli to get them corrected. Be that as it may . . .
Now that it is up and ifconfig shows the adapters as I expect/want, I try to ssh from the host system, and get this:
ed@ed-Gazelle-00:~$ ssh root@vbol83-01
Warning: the ECDSA host key for 'vbol83-01' differs from the key for the IP address '192.168.0.200'

Are you sure you want to continue connecting (yes/no)? yes
