[Xen-devel] Set cpu_weight and cpu_cap at boot time

[Dominik Klein <dk@xxxxxxxxxxxxxxxx>]

Hi

"xm create --help_config" gives:
...
cpu_cap=CAP          Set the maximum amount of cpu.
                     CAP is a percentage that fixes the maximum amount 
of cpu.
cpu_weight=WEIGHT    Set the cpu time ratio to be allocated to the domain.
...

As it does not work I looked at the py Files and found this:

/usr/lib/python/xen/xend/XendConfig.py :
...
# List of legacy configuration keys that have no equivalent in the
# Xen API, but are still stored in XendConfig.
LEGACY_UNSUPPORTED_BY_XENAPI_CFG = [
    # roundtripped (dynamic, unmodified)
    'shadow_memory',
    'security',
    'vcpu_avail',
    'cpu_weight',
    'cpu_cap',
    'features',
    # read/write
    'on_xend_start',
    'on_xend_stop',
    # read-only
    'domid',
    'start_time',
    'cpu_time',
    'online_vcpus',
    # write-once
    'cpu',
    'cpus',
]
...

So it looks like it cannot work yet. Are there any plans to change/fix this?

This is xen 3.1.0

Dominik
