Yup, that's pretty much exactly what libguestfs is good for -- though, 
not being familiar with xenstore, let me add that the VMs need to be 
down before you try to modify their filesystems.

I suggest scripting what you're trying to do with guestfish before going 
on to the C API -- it's pretty easy to look at how any guestfish command 
is implemented in C, and so to do what you want natively if that's your 
inclination.
