Nesting VMware Server 2 inside a ESXi 5.1 VM

Greetings,

For historical development reasons I need to support several Linux hosts running VMware Server 2.0. I have successfully virtualized the Linux hosts onto ESXi 5.1, but when I attempt to power up the VM I get the message "You may not power on a virtual machine in a virtual machine"

I have added the vhv.enable = "TRUE" to the /etc/vmware/config file.

I have found lots of discussion about Workstation, Hyper-V and ESX inside of ESX, etc, but nothing regarding VMware Server.  I understand that it's EOLed, but was hoping that someone might have some insight on this.

Thanks,

Lewis
