xen discuss - Oct 2007 - domain migration

Hi,

I have a few questions about Xen in Solaris:

1. Is migration supported yet?  Maybe I missed it, but I can''t find any
info on this topic.

2. If it is supported, or planned to, how does migration handle the
content of a virtual disk assigned to a DomU?  Does it always copy
entire the virtual disk content or does it depend on the type of storage
involved?  One scenario I am thinking of is the two systems seeing the
same Fibre Channel disk.

Thank you for any clarification/answer on my questions.

I know that migration of PV domains works; I don''t know all the details
of
migrating HVM domains, sorry.

AFAIK, the storage must be visible from both hosts *under the same name*; I 
have successfully migrated between hosts accessing the image over NFS.
