I can see the hooks running in the vdsm logs, but can't tell what they are doing from there. They are not attaching the sriov card instance to my VM though, so I'm at a loss.

You may also share the bit of vdsm.log from vmCreate until failure.

Failing that, some explicit documentation on EXACTLY what string should be used for the hook would be nice. My first pass at it resulted in an improper string that caused my host to crash/hang and reboot when I attempted to start a VM with it the first time.

I think that Darrel means something like

    Bug 1086329 - [RFE] semi-automatic hook registration

(or maybe a bit less fancy). It would be cool to add some introspection
to the hook framework, so that Engine learns about available hooks and
their custom properties from the nodes.
