I don't really have any ideas on the error -100. Error -100 means there was
a mailbox error, so something failed in the initial communications setup
between the PF and VF, but I don't know what exactly went wrong.

I'm grasping at straws, but try using a smaller number of VFs initially,
like 2? And check to see if VT-d is enabled in your BIOS? (Though I
would've expected iovctl to fail).
