Hello,
When i create a guest with option 'cpus="0-3"' on the command line, xl can not 
parse the config. But it works well when i specify 'cpus=1' on the command 
line. I read the man page xl.cfg, learned that xl support the following format:
"0-3,5,^1"
so  it would be very nice if xl can support this format on the command line too.

Also i have file a bug on bugzilla: Bug 1886 - option `cpus="0-3"` works well 
when you specify it in a configure file, but it give a error feadback when you 
add it to the command line



The following are the  details:
