ERROR : Failed handling answer file: Given host does not listen on port 22: 10.120.20.49

I get the above error on my Centos 7 allinone host when adding the new hyper-v compute node to the packstack questions file. This is a windows 2012 server hyper-v install and doesn't have ssh running on it. Am I missing a configuration change or is something missing on the hyper-v server? Randy

Added my new 10.120.20.49 node and exclude the current Centos 7.0 allinone host.
