Learn how VMware Skyline Advisor and Skyline Health Diagnostics work together to provide proactive intelligence and self-service log analysis.

Use Skyline Advisor to avoid issues before they occur across VCF, vSphere, vSAN, NSX, vROps & Horizon. Skyline Findings are based on top KBs, VMSAs/CVEs and design best practices.

Use Skyline Health Diagnostics to root cause vSphere & vSAN logs when an issue occurs. Skyline Health Diagnostic Findings are based on top KBs and VMSA/CVEs. You can use the Skyline Health Diagnostics tool in online or offline mode.

If you require additional help from technical support, please use Skyline Advisor to initiate a Log Assist to reduce time to upload logs. TSEs can also initiate logs to reduce effort.

Symptoms

You may receive these errors, which can indicate blocked ports:

Unable to contact the specified host

The host is not available, there is a network configuration problem, or the management services on the host are not responding

Failed to connect to peer

Error: Failed to connect to server

The operation failed

Incorrect user credentials

Unable to SSH to the source machine

Please check if a firewall is blocking access to the SSH daemon on the source machine

Failed to clone the volume

Unable to connect

FAILED: The request refers to an unexpected or unknown type

Failed to connect ISO image to remote VM

FAILED: unable to obtain the IP address of the helper virtual machine

ssh: Could not resolve hostname

Name or service not known

FAILED: An error occurred during the conversion

Unable to obtain IP addresss of helper virtual machine

A general system error occurred: unknown internal error

A file I/O error occurred while accessing

Purpose

This article describes the ports required to be open for VMware vCenter Converter.

Following the article and ensuring the ports are open ensures that common firewall configurations in your environment are compatible with Converter.

Resolution

VMware vCenter Converter fails if one or more required ports are blocked. Follow the section that matches your conversion scenario.

In this article, these terms are used:

Source computer

The physical or virtual machine that is being converted.

Converter server

The server portion of VMware vCenter Converter. In a typical installation, both the Converter server and Converter client are installed at the same location. By default, this is the installation method that is used.

Converter client

The client portion of VMware vCenter Converter. In a custom installation, the Converter client can be installed to a different computer than the Converter server.

VirtualCenter

The VirtualCenter computer that is being used as the conversion destination, if such was chosen.

ESX

The VMware ESX host that is being used as the conversion destination, if one is chosen, or the ESX host that is hosting the target virtual machine.

Fileshare path

The path to a virtual machine's .vmx file, if the source is an existing or standalone virtual machine, or the path to a directory if the destination is to be a standalone virtual machine.

Standalone virtual machine

A virtual machine that is being managed by a VMware product other than VMware ESX.

Helper virtual machine

When converting a powered on Linux operating system (P2V), this is the target virtual machine that is being used temporarily for the purpose of copying files from the source computer. It uses the TCP/IP information that is entered in the Converter wizard for the target virtual machine. Ensure that this IP address can communicate directly with the source computer.

Notes:

If you perform a corrective action, determine if the problems initially encountered are still being experienced.

To test port connectivity, do so from a command or shell prompt. For more information, see Opening a command or shell prompt (1003892).

To test TCP port connectivity use the telnet command. For more information, see Testing port connectivity with Telnet (1003487).

To test UDP port connectivity from Linux or MacOS use the traceroute command. For more information, see a traceroute man page.

To test UDP port connectivity from Windows use the Portqry utility. For more information, see the Microsoft Knowledge Base article 310099.

For powered-on Windows conversions to vCenter destinations, Proxy Mode feature in Converter 6.0 is introduced. By selecting this option, no direct connectivity is required from the source machine to the destination ESX host.

Note: The preceding links were correct as of March 15, 2009. If you find a link is broken, provide feedback and a VMware employee will update the link.

Notes

Source computer

445, 139, 9089 or9090

137, 138

If the source computer uses NetBIOS, port 445 is not required. If NetBIOS is not being used, ports 137, 138, and 139 are not required. If in doubt, ensure that none of the ports are blocked.

Port 9089 is used for Converter Standalone versions,and 9090 isused for the Converter plugin.

Note: Unless you have installed Converter server to the source computer, the account used for authentication to the source computer must have a password, the source computer must have network file sharing enabled, and it cannot be using Simple File Sharing.

Converter server

VirtualCenter

443

Only required if the conversion target is VirtualCenter.

Converter client

Converter server

443

Only required if a custom installation was performed and the Converter server and client portions are on different computers.

Source computer

ESX/ESXi

443, 902

If the conversion destination is vCenter Server, only port 902 is required from the source to the ESX/ESXi host management IP.

Converting a powered on Linux operating system (P2V)

Note: These are the default ports. If custom ports were used when installing vCenter Server, these will need to be changed to match your environment.

The helper virtual machine must be able to establish an SSH connection with the source computer. By default the helper virtual machine gets its IP address assigned by DHCP. If there is no DHCP server available on the network chosen for the target virtual machine you must manually assign it an IP address.

Converting an existing virtual machine (V2V)

Note: These are the default ports. If custom ports were used when installing vCenter Server, these will need to be changed to match your environment.
