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
Regards
Dominik

Well that does not change that both configuration items do not work (for my PV linux domains in xen 3.1.0) Regards Dominik _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

[solved] Re: [Xen-devel] Set cpu_weight and cpu_cap at boot time
> That may well be the case, but it probably takes a bit more digging > before that can be solved.It actually works. It was my fault. I tested it by setting cpu_weight in the config and the RESTARTING the domain. This did not read the new value but use the last one. SHUTDOWN and CREATE does recognize the new value in the config file. Sorry to bother you.
