This is applicable in below VC versions:
VC7.0P02(7.0 U1c)
7.0U1d GA
VC 7.0U2
VC 7.0 P03

Workaround:
When creating the customization specification, the mac addresses should be set in the ascending order of pciSlotNumber. The values of pciSlotNumber can be found from the .vmx file as in the below example.
If the ethernet0.pciSlotNumber > ethernet1.pciSlotNumber,
it needs to set the mac address of ethernet1 first and then set the mac address of ethernet0 in the customization spec.
