Hello,

I have problems with restoring Xen''s saved domU.

my OS and hardware configuration is:
  - Debian Sarge 64 bit with 2 x Opteron
  - 8 GB RAM
  - LVM + 3ware 9550

and Xen 3.0.1 compiled from sources.

When I''m trying to restore saved domain (Debian too - on 2.6.12) I
hypervisor crashes...

I have tried to search in mailing list archives, but found nothing
similiar. Did anyone meet something like that below?

Cheers,
Adam
