It's not necessary to build Xen in bare metal - it still has access to write to 
the disk in dom0.

Whether there's a faster way of doing it depends on what you're modifying. If 
it's Xen itself then a reboot is required to modify. If a daemon or utility you 
may be able to restart just that.

The other alternative is to run Xen inside itself or another VM, assuming it 
supports nested SLAT/EPT. It'll probably be faster to reboot a VM than the host 
system.

Beyond that, buy an SSD?
