Symptoms
Unable to import RAS_HALB_Appliance-21.0.26247 appliance into vCenter 8 with ESXi 7.0U3. The deployment fails with the following error:
"configSpec.guestId" argument was specifiedCause
This issue is caused by an incorrect value of vmw:osType in the OVF descriptor file.
- VMware 7 is more lenient with OVF parameters and may tolerate slightly mismatched or deprecated
vmw:osTypevalues. - VMware 8 enforces stricter validation and fails if the
guestIdis not recognized.
Resolution
To resolve the issue, manually correct the vmw:osType value in the OVF file:
1. Open the OVA archive. Use a tool like 7-Zip or WinRAR to extract RAS_HALB_Appliance-21.0.26247.ova.

2. Edit the OVF file. Locate and open the file prls-vm-vmware-21.0.0.-26247-20251108.ovf in a text editor (e.g., Notepad++).

3. Find and replace the OS type. Locate the line:
<OperatingSystemSection ovf:id="100" vmw:osType="other6xLinux64Guest">
and replace it with the correct one:
<OperatingSystemSection ovf:id="100" vmw:osType="otherlinux64guest">

4. Save and redeploy. Save the modified .ovf file. Repackage the OVA (optional) or deploy the OVF directly using vCenter 8.
