Hi Andrew,

Without your patch, I can save/restore cpu_weight and cpu_cap as follows.

# xm create vm1 cpu_weight=512 cpu_cap=100
Using config file "/etc/xen/vm1".
Started domain vm1 (id=1)
# xm sched-credit -d vm1
Name                                ID Weight  Cap
vm1                                  1    512  100
# xm list --long vm1 | grep cpu_
    (cpu_weight 512)
    (cpu_cap 100)
    (cpu_time 22.504581706)
# xm save vm1 /root/vm1.save
# xm restore /root/vm1.save 
# xm sched-credit -d vm1
Name                                ID Weight  Cap
vm1                                  2    512  100
# xm list --long vm1 | grep cpu_
    (cpu_weight 512)
    (cpu_cap 100)
    (cpu_time 2.200074199)


What is your problem?
How can I reproduce your problem?

FYI, can changeset 19955 help you?

Best regards,
 Kan
