OK.  I generally recommend keeping LVM outside VMs anyhow, to ease 
administration.

I don't quite understand what you're trying to do?  Could you please provide a 
little more detail?

Is the idea just to make the resizing of LVM volumes visible to the guest?  
I'm not sure exactly why this would be broken but I can imagine it might have 
been.  It'd certainly be a useful feature to have back.

Cheers,
Mark
