Indeed, I see "Connection refused".
Let's investigate on this.
On the conversion server (serv-p2v-adm1), before running all this, I
did a "iptables -F" (and a restart of NFS - not knowing if it was
needed), so I have no rule in iptables now.
Do I have to find a way to increase the verbosity of sshd in
/var/log/secure?
You might want to check that sshd allows port forwarding
('AllowTcpForwarding yes' in /etc/ssh/sshd_config).
It would be useful to know what the actual sshd failure is.
This is how ssh is invoked on the virt-p2v side:
https://github.com/libguestfs/libguestfs/blob/master/p2v/ssh.c#L174
plus
https://github.com/libguestfs/libguestfs/blob/master/p2v/ssh.c#L595
Another point : as I wrote it before, I have no way to get a shell
prompt on the source machine, because alt-F1 leads to a blinking
screen trying to run virt-p2v and failing and respawning.
I nmap'd this source host, and saw that ssh was open.
In order to run the action step by step, is there a way to connect
to this root account? What password? (already tried
secret/p2v/root/password/PASSWORD/redhatrulez but that did not the
trick)
I'm fairly sure the root account is disabled, and sshd isn't supposed
to be running, but apparently it is (a bug). It's also a bug that
there is no shell on another other virtual console, but TBH I don't
know how to fix that ...
