A customer of mine got an appliance from a software vendor. The appliance was delivered as ZIP file with a VMDK, a MF, and an OVF file. Unfortunately, the appliance was created with VMware Workstation 6.0 with virtual machine hardware version 6, which is incompatible with VMware ESXi (Virtual machine hardware versions). During deployment, my customer got this error:
unsupported hardware family 'vmx-06'
The OVF file includes a line with the VM hardware version.
If you change this line from vmx-06 to vmx-07, the hash of the OVF changes, and you will get an error during the deployment of the appliance because of the wrong file hash.
