This article provides a comprehensive guide to understanding, diagnosing, and resolving this issue, offering actionable steps for a successful P2V migration. Why Does This Error Occur?

In this post, I’ll explain why it happens and walk you through the proven fixes.

Note: Adding diffie-hellman-group1-sha1 is often the magic fix for older Converter versions interacting with newer Linux kernels.

This error typically halts the conversion wizard right after you enter the source machine's credentials. Because Linux migrations rely on a complex interplay of SSH permissions, network routing, firewall rules, and specific system binaries, a single misconfiguration can cause the query to fail. Note: Remember to revert your /tmp mount settings

Note: Remember to revert your /tmp mount settings back to noexec once your P2V pipeline successfully initializes.

If all else fails, consider:

statements, they can break the SFTP/SCP connection used by Converter to transfer files. methodically check dependencies and SELinux.

Look for the line PermitRootLogin and change its value to yes : PermitRootLogin yes Use code with caution. Save the file and restart the SSH service:
