When migrating a zone, you would have to find some way to extricate the

hard.


OpenVZ (similar to zones, from my understanding) can do this on Linux.

If you want live migration on Solaris, and you are using x86/x64 machines,
then you should be looking at Xen.

Does running on sun4v LDOMs help provide a path to this?  To someone
that hasn't really looked at how LDOMs get their initial state, it
seems as though this would be quite doable.
