Adding rhev-tech
Something I found interesting from the -vvvv ansible logs was the
difference in connect options between SSH and SFTP. I see the SSH connect
option "-o StrictHostKeyChecking=no" that was added to the new host
<https://github.com/oVirt/ovirt-ansible-hosted-engine-setup/blob/master/tasks/bootstrap_local_vm/02_create_local_vm.yml#L11>,
but I don't see those options on the subsequent SFTP command. I'm assuming
the SFTP command is uploading the ping module (maybe because of the SSH
proxy command logic linked above...) It seems to me that the logic of the
playbook link above is wrong. There is a conditional check that determines
whether or not the new HE will be subjected to key checking. Because this
is a brand new HE VM, nobody will know the host_key, and so
host_key_checking must not be done.
A few select lines from the ansible -vvvv logs:
<rhvm.home.lab> SSH: EXEC sshpass -d12 *ssh* -vvv -C -o ControlMaster=auto
-o ControlPersist=60s -o 'User="root"' -o ConnectTimeout=10 *-o
StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null* -o
'ProxyCommand=ssh -W %h:%p -q r...@rhhi1.home.lab' -o
ControlPath=/root/.ansible/cp/9de9431b6b rhvm.home.lab '/bin/sh -c
'"'"'echo ~root && sleep 0'"'"''
...
