Vmware Standalone Converter Unable To Query The Live Linux Source Machine Full -
The error “Unable to query the live Linux source machine” in VMware Converter Standalone usually stems from SSH environment mismatches, missing system tools, security module interference, or OS version incompatibility. By methodically testing SSH, verifying required binaries, checking SELinux/AppArmor, and reviewing logs, most issues can be diagnosed. For modern Linux distributions, switching to an alternative P2V tool or performing an offline conversion is often the most reliable solution.
When using VMware vCenter Converter Standalone, the error "Unable to query the live Linux source machine" typically occurs because the software cannot retrieve essential hardware and system information from the source Linux machine. Common Causes and Troubleshooting Steps
Below is a guide to resolving this issue based on known technical causes and Broadcom Knowledge Base articles: 1. SSH and Terminal Environment Issues
Remove 'echo' Statements: Ensure the .bashrc or .profile files for the user account (typically root) do not contain any echo or interactive commands. These can disrupt the SFTP stream the converter uses to copy information.
Verify Shell Type: The source user should have /bin/bash as their default shell.
SSH Configuration: Ensure the SSH daemon is running and reachable on port 22. Some environments may fail if the SSH configuration uses unsupported HMACs; VMware Converter typically expects hmac-sha1 or hmac-md5. 2. File System and Execution Permissions
Unmount Duplicate Mountpoints: The converter may fail if a single disk device is mounted at multiple locations. Ensure each device has only one mountpoint in the file system.
Writable /tmp Directory: Ensure the /tmp directory on the source is writable and allows the execution of scripts.
Change Sysinfo Path: If /tmp is mounted with noexec, you can modify the converter-worker.xml file (located on the Windows machine running the converter) to use a different directory by uncommenting the /root. 3. Network and Security Settings

Quick Fixes & Troubleshooting Checklist "unable to query the live source machine" in P2V convert
If you're getting the "Unable to query the live Linux source machine" error in VMware Standalone Converter, it usually means the tool can't properly communicate with your Linux machine or run its inventory scripts.
Here is a breakdown of the most common causes and how to fix them. 1. SSH & Credentials Issues
The Converter uses SSH to log in and run discovery commands. PermitRootLogin PermitRootLogin yes is set in your source machine’s /etc/ssh/sshd_config . If you are using a non-root user, that user have passwordless sudo privileges (configured via username ALL=(ALL) NOPASSWD: ALL SFTP Compatibility contains an
statement or any command that produces text output upon login, it can break the SFTP connection the Converter uses. Move these statements to .bash_profile Encryption Mismatch
: Older versions of the Converter may struggle with modern SSH HMACs. Ensure your sshd_config supports older algorithms like if the connection fails immediately. 2. File System & Partitioning Errors
The Converter often fails if it finds a disk layout it doesn't recognize. Duplicate Mount Points
: Ensure each disk device is only mounted once. Multiple mount points for the same partition (e.g., mounted at both ) will cause a query failure. Unrecognized Volumes
: If your source machine uses NVMe disks or certain LVM configurations not supported by your specific Converter version, it may fail to map the drives. Broadcom support portal 3. Permission & Execution Blocks The discovery process involves running a script called vmware-sysinfo.sh directory. Unable to query live Linux source machine
The "Unable to query the live Linux source machine" error in VMware vCenter Converter Standalone usually happens because the tool cannot gather hardware information via SSH or execute its required "sysinfo" scripts. 1. Fix Multiple Mount Points (Critical) Converter expects each source file system to have exactly one unique mount point : If a single device (e.g., ) is mounted in two places (like /mnt/backup ), the volume analysis fails. : Check your mount points with the command and
any duplicate or extra entries before starting the conversion. 2. Solve Execution Permissions in The Converter copies a script to the source's directory to gather system info. If is mounted with the flag, the script will fail to run. Fix A (Remount) : Temporarily remount with execution rights: mount -o remount,rw,exec /tmp Fix B (Change Path) : On the Windows machine running Converter, edit the converter-worker.xml file (found in C:\ProgramData\VMware\VMware vCenter Converter Standalone\ ). Uncomment the
scripts output text (like a "Welcome" message), it can break the automated query. Comment out any Root Login PermitRootLogin yes /etc/ssh/sshd_config Shell Assignment : Ensure the user has a valid shell like assigned in /etc/passwd , rather than /sbin/nologin 4. Network and Firewall Check

Troubleshooting VMware Converter: "Unable to Query the Live Linux Source Machine"
Running into the dreaded "Unable to query the live Linux source machine" error while attempting a Physical-to-Virtual (P2V) or Virtual-to-Virtual (V2V) migration using VMware vCenter Converter Standalone can bring your migration project to a screeching halt.
This specific error triggers when the Converter fails to properly gather hardware and volume configuration details from your powered-on Linux system. Troubleshooting Steps To resolve the error, follow these
Let's break down the most common culprits and how to bypass them. 🔍 The Big Three Causes
When this error pops up, the logs usually point to one of these three architectural or security bottlenecks: 1. The Multi-Mount Conflict
This is arguably the most common cause documented in the Broadcom Knowledge Base.
The Problem: VMware Converter expects every source file system to map to a single, unique mount point. If you have a single disk device mounted in multiple directories (like a disk bound to / and at the same time to a directory under /var), the partition analysis logic breaks.
The Clue: Look at your vmware-converter-worker.log for a line saying: No disks for volume with id '/dev/...' and label.
The Fix: Temporarily umount the secondary mount points on your Linux machine until the initial query and cloning task completes. 2. Sudo Without Password Prompting
To pull raw hardware and disk layouts, the Converter executes commands via SSH using administrative permissions.
The Problem: If you aren't logging directly in as root and are instead using a standard user with sudo privileges, Converter will fail if sudo asks for an interactive password prompt.
The Fix: Grant your conversion user passwordless sudo access. Run visudo on the Linux source and append:your_username ALL=(ALL) NOPASSWD: ALL 3. Blocked Executables in /tmp
VMware Converter executes its helper queries by deploying a sysinfo tarball package to the source system's /tmp directory and executing a script.
The Problem: Many security-hardened Linux environments mount the /tmp directory with the noexec permission flag. This hardens the server but stops the script right in its tracks with a "Permission denied" error.
The Fix: You can either temporarily remount /tmp with execution rights using mount -o remount,rw,exec /tmp or change the target path by editing the converter-worker.xml file on the Windows machine hosting the Converter software to point to another writable directory. 🛠 Quick Troubleshooting Checklist
If none of those big three solved your issue, check off these foundational basics:
🔐 Check .bashrc for echoes: If the user profile logs in and returns an interactive text string (like a welcome banner or an echo command in .bashrc), it confuses the SFTP transfer mechanism used by the tool. Move echoes to .bash_profile.
🔌 Network & SSH Ports: Ensure that ports 9089 and 443 are reachable, and verify that standard SSH port 22 is fully accepting connections from your Converter machine.
🔢 SSHD Ciphers/HMACs: Older versions of Converter rely on standard, sometimes deprecated algorithms like hmac-sha1. If your Linux server strictly demands newer SHA2 algorithms, Converter may fail to authenticate. Should be /bin/bash or /bin/sh , not /sbin/nologin
💿 Unsupported RAID: Remember that the standalone converter does not support native Software RAID (MDRAID) setups.
