Add new constant for pending job status
This constant contains the job status' “queued”, “waiting” and“cancelled”.
Add support for cpu_cap and cpu_weight Xen params
This patch adds support for Xen's CPU scheduler 'cpu_cap' and'cpu_weight' parameters.
Ganeti default values (cap: 0=unlimited, weight: 256) are Xen defaults.
cpu_cap is not validated correctly because of actual Ganeti limitation...

It is dangerous to have this block size as a global constant as thatcould give the impression of it being easily changed. Doing so withoutfurther adjustments to how “dd” is called will lead to disks not beingwiped properly....
