Xen users - Nov 2005 - Problems with saving of domains

Hallo there,

I''m running Xen unstable on a x86_64 dual xeon machine.
Everything works flawless except for saving of domains.

When I issue a xm save <name> /var/lib/xen/save/<name>

it throws out  the following message:

Save/restore is not currently supported on 64bit guests although we
expect to check in support shortly.

Ok that makes sense. I turn off save on shutdown for now then.
