[Xen-users] Problems with saving of domains

[Bas van den Heuvel <bas@xxxxxxxxxxxxxxxxxxxxxx>]

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:
