I have 2 questions:

 1. I was not able to let the guest know that the partition size was changed.
 2. I was not able to use block-attach with the same backendfile to different 
machines (eg: guest + dom0)

I've read that block-reconfigure could've been used for this, except that it 
wasn't designed to work for filebased vbd on PVs, only for switching CDROMs 
in HVM

When you use a local disk on a machine, you can use fdisk to change partitions 
and sizes, it then rereads the partition table to reflect those changes.

Since i'm not using a disk, but directly partitions, isn't it possible to just 
give a signal to the guest that it should recheck the partition? can be from 
the guest itself.

Some kind of workaround?
