    Maybe that is not supported by the virtual eth0 card in VMware. Remember that a VM is not real hardware, it is virtual.

    I suggest you check on a VMware site. They are more likely to have a solution or an answer. I think it is definitely a VMware problem.

    Have you tried setting these parameters in the host os. After all eventual there is a real hardware interface and it seems that this is the one that needs tickled since it is the one that interfaces to the real world. Just a thought.
