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 can compare the generated livirt xml send to qemu by vdsm and 
compare to what you expected to happen by the hook.

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.

each hook has a README - maybe send a patch to elaborate more on the one 
not clear enough to you?

yes. it was correct.
