RFC 4122 is for URN embedding, that's a specific use. We are not following
that syntax anyway since it's not an URN, we really don't need to encode this
as an URI, only as an unambiguous ASCII string, and the current format does
the job minimally.
Well, for example "xm list --long" uses the format with '-' (and
xend, filesystems, and ... everywhere). I think it's better follow
old manners although we don't need it.
I've commited virDomainGetUUIDString() and virDomainLookupByUUIDString()
functions and the virsh command supports domain look up by UUID now.
All these changes use '-' format ;-) It's nothing important, but I
think it's better support conversion from/to UUID string in the
library rather than duplicate this code in every libvirt application.
Now we use UUID in gnome-virt-manager (+ in dbus API), virsh and my
plan is use it also in gnome-applet-vm.
