Hello
I hadn''t yet investigated save/restore, but it seems not to work for
me.
Running Mandrakelinux 10.1 (ish - updated not reinstalled) on an AMD
ATHLON 2400 I have a crash restoring the domain:
root@xen0# xm save aaa aaa.saved
...
root@xen0# xm restore aaa.saved
The console output is as follows:
Unable to handle kernel paging request at virtual address 0000c000
printing eip:

You might want to instrument up time_resume in arch/xen/i386/kernel/time.c, or I may find some time to look later in the week. -- Keir ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
