Honestly, I don't know if that would work.

There are two types of supported migration:

xm migrate 

This does an 'offline' migration from one machine to another. It's equivalent
to the steps you give above: the domain is suspended in full, then resumed on
another machine.

xm migrate --live

This does live migration as described in the Xen documentation and papers.

Yes. The meaning and advantages of migration are explained in the Xen
publications you can find on the internet. At this time, there's no real
difference between Solaris domUs and other implementations in this respect.

Note that the current Solaris Xen port available on opensolaris.org only
supports migration of single-cpu domains, though we expect this to change
relatively soon.

john
