They are different. In the case of Live patching, you are replacing 
small portion of the hypervisor with a new version. This works quite 
well when the changes are not complex and doesn't require to mutate your 
data.
In the case of live-update, the existing hypervisor will be replaced by 
a new version without requiring a restart of your VMs. This would allow 
you to upgrade between stable release (and possibly major) versions of Xen.
So far, only live-patching is available upstream. But there is plan to 
get live-update support for Xen.
