Which is required by vCenter Converter Standalone to convert a physical Red Hat Enterprise Linux 7 machine to a virtual machine?

vCenter Converter Standalone supports hot cloning of powered-on Linux machines; the machine does not need to be powered off, unlike some cold-clone Windows scenarios.

vCenter Converter Standalone uses SSH to remotely access the Linux source machine, push a helper agent, and read disk data during the conversion process. Without an active SSH daemon, Converter cannot establish the required connection and the conversion job will fail at the source machine discovery stage.

Converter identifies and connects to the source machine by IP or hostname, and DHCP-assigned addresses are acceptable as long as the address remains stable during the conversion job.

A fully-qualified domain name is not required; Converter can connect to the source machine using its IP address directly without DNS resolution.
