Values of cpu_weight and cpu_cap are lost after xend restart
For managed domains in state 'halted' I always get default values
for cpu_cap / cpu_weight after xend restart.
This is because the names of parameters differ between a SXP file to
create a VM (here the parameter names are cpu_cap / cpu_weight) and
a SXP file of a managed VM (here vcpus_params (cap 0) (weight 0)).
But XendConfig.py reads only cpu_cap / cpu_weight and if not found,
default values are used.
?
The patch reads first vcpus_params (cap, weight), if not found then cpu_cap,
cpu_weight and if both parameters are missing it uses the default values.
?
