Vmware Standalone Converter Unable To Query The Live Linux Source Machine -

Introduction VMware vCenter Converter Standalone is a powerful tool for converting physical machines (P2V) and third-party virtual machines to VMware virtual appliances. However, IT administrators frequently encounter a frustrating roadblock when attempting to convert a live Linux source machine: "Unable to query the live Linux source machine."

ssh -v root@<linux_source_ip> If you are prompted for a password or receive Permission denied , correct authentication first.

This article explains the root causes of this error and provides a step-by-step guide to resolving it. The error message indicates that the Converter (running on a Windows or Linux management machine) cannot successfully interrogate the source Linux host via SSH. The Converter relies on a temporary agent (often referred to as the Converter Helper or p2v agent ) that it uploads and executes on the source machine. If the helper cannot run or communicate back, the query fails. The error message indicates that the Converter (running

echo $SHELL # Should show /bin/bash If root uses a different shell (e.g., /bin/sh ), change it:

PermitRootLogin yes MaxSessions 10 AllowTcpForwarding yes PermitTTY yes Then restart SSH: systemctl restart sshd echo $SHELL # Should show /bin/bash If root

While PermitRootLogin yes is required for Converter, consider using key-based authentication and restricting the source IP address in /etc/hosts.allow or via firewall rules for security. Step 4: Temporarily Disable SELinux/AppArmor SELinux (enforcing mode) frequently blocks the Converter’s helper agent. To test:

Converter 6.2+ supports key-based authentication. Generate an SSH key pair and add the public key to /root/.ssh/authorized_keys on the source Linux machine. Step 2: Check Required Commands and Packages The Converter helper script executes commands like lsblk , blkid , fdisk , lvm , df , uname , and perl . Ensure these are installed and in $PATH for root. the query fails.

For AppArmor (Ubuntu/Debian):

systemctl stop apparmor systemctl disable apparmor # only for testing The Converter expects /bin/bash to exist and be the default shell for root.

This error typically occurs during the "Source Machine" selection phase, immediately after providing the Linux machine’s IP address, root credentials, or SSH key. The converter initiates a connection but fails to retrieve hardware or operating system information, halting the process before conversion can begin.

setenforce 0 # Temporarily disable SELinux If conversion succeeds, you can create a custom SELinux policy or run the converter in permissive mode.
