Fusion, netbooting OS X and the bless command, something isn't working.

Howdy all,

I have what may be a unique situation and I'm looking for some guidance.

I've got Fusion 7.1.0 (2314774) up and running on a MacBook Pro and everything is working just fine except for netbooting to install versions of OS X.

I can install OS X in to a VM with the standard installers and that works just fine. What I am then trying to do is use the following bless command to get the VM to reboot from a Netboot server.

sudo bless --netboot --booter tftp://nnn.nnn.nnn.nnn/NetBoot/NetBootSP0/mavericks.nbi/i386/booter -kernelcache tftp://nnn.nnn.nnn.nnn/NetBoot/NetBootSP0/mavericks.nbi/i386/x86_64/kernelcache --options "rp=nfs:nnn.nnn.nnn.nnn:/private/tftpboot/NetBoot/NetBootSP0:mavericks.nbi/NetBoot.dmg"javascript:;

All of the relevant files do exist and are all on the same server. It is the case that the Netboot server is not on the same subnet/VLAN as the MacBook running fusion. All seems to be fine and the bless command reports that the EFI has been updated. However, when I then reboot the VM it simply boots back in to the vanilla OS X 10.9 that is on the VM.

Can anyone spot anything that I am missing? Should this work?

Please and thank you
