Hello all,
I'm dealing with the very same problem. I get the mentioned error even though I can connect through SSH, IPtables firewall is disabled and hosts.allow and hosts.deny are empty. Both machines, the Helper VM and the physical machine where the source VM is running on VMware Workstation, are in the same network.
It is true that this is not a P2V really, but It is the same problem in the end. Any help will be much appreciated!
Regards,
Alex.
PD: I fixed it changing the source VM networking to bridged in VMware Workstation and making sure the source and helper VM were going to be able to resolve the name of the host were the helper VM was going to be deployed, inside vCenter. So, I suggest to make sure all the physical and virtual machines are in the same network and able to resolve all the names. Hope this helps somebody.
