| There's a pretty cool thing caled libguestfs, and a tool called guestfish
I've never used it (just stumbled on it recently) but it should do exactly what you need :-) And it supports RBD.

I want to mount this bootable image on the hypervizor node to access its filesystem and fix a file I messed up in /etc/ so I can get the VM to boot.

How can I find and use the partition inside this raw, bootable file image?
You've probably created it using features that the kernel client you have installed doesn't understand. You'd need to either use a newer kernel or (more likely) just hook it up to a VM with QEMU. -Greg
