Just like a system reboot is not exactly the same as powerdown and power
up, restart just WARM RESTARTS the guest - so it essentially just tells
the guest to start over from scratch. So it uses the stored
configuration of the guest, rather than re-reading the guest config
[note that a guest configuration isn't necessarily a file - you can
specify every single component as a command-line argument to the "xm
create" command, so "xm create" actually stores all the values given to
it, and any updates are also changing the stored values]. 

So they are not and can not be exactly the same.
