Resolving OVA Import Issues in VMware ESXi: Compatibility and Template Errors

Description

Users may encounter a specific error when attempting to import a Cymetricx image file (.ova) into VMware ESXi. The error message typically reads:

"Issues detected with selected template. Details: - -1:-1:VALUE_ILLEGAL: No supported hardware versions among [vmx-14]; supported: [vmx-04, vmx-07, vmx-08, vmx-09, vmx-10, vmx-11, vmx-12, vmx-13, vmx-14].”

This indicates a compatibility issue between the VMware ESXi version and theova template being used.


Environment

  • VMware ESXI

Cause

The error arises due to a mismatch between the VMware ESXi version and the hardware versions supported by the .ova template.

Recommended Actions

1- File Conversion and Extraction: Change the extension of the file from .ova to .zip and extract the file using an archiver tool like WinRAR or 7zip. the extracted file should contain the following: an ovf file, .mf file and .vmdk file.


2- Edit the .ovf File: Edit the extracted .ovf file with a text editor (e.g., Notepad).

3- Modify Virtual System Type: Locate the line:

<vssd:VirtualSystemTypevmx-15</vssd:VirtualSystemType>

and adjust it according to the ESXi version's supported hardware. For instance, change vmx-15 to vmx-14, based on the error message.


Change it to

<vssd:VirtualSystemTypevmx-14</vssd:VirtualSystemType>

4- Save Changes: After modification, save the .ovf file.

5- Update File Hash: Generate a new SHA256 hash for the edited .ovf file using PowerShell:

  1. (Get-FileHash **<OVF FILENAME>**.ovf -Algorithm SHA256 | Select-Object -ExpandProperty Hash).ToLower()

Note: since the filename of the .ovf file would be similar to “CentOS+8+64-bit_v4.0_1.4.163_Migration_02092023_ESXI6.7” then the command would be

  1. (Get-FileHash CentOS+8+64-bit_v4.0_1.4.163_Migration_02092023_ESXI6.7.ovf -Algorithm SHA256 | Select-Object -ExpandProperty Hash).ToLower()

Example


6- Modify .mf File: Replace the contents of the .mf file with the new SHA256 hash obtained in the previous step.

Additional Notes

  • Ensure all modifications are accurate to prevent further compatibility issues.
  • This process should be performed carefully to avoid corrupting the image file.
