The helper binary vmware-converter-helper has a diagnostic mode:
VMware Converter uses SFTP to move helper files to the source. Ensure the SFTP subsystem is enabled in sshd_config . Look for: Subsystem sftp /usr/libexec/openssh/sftp-server
sudo /opt/vmware-converter-helper/vmware-converter-helper --debug
: Ensure the /tmp directory on the source is writable and allows the execution of scripts.
