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: Description of problem: 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. Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1. Install a host with xen4 2. Create a guest, add option 'cpus="0-3"' on the command line # xl -v create hvm-7.0-64-1.cfg cpus="0-3" Parsing config from hvm-7.0-64-1.cfg hvm-7.0-64-1.cfg:28: config parsing error near `-3': lexical error warning: Config file looks like it contains Python code. warning: Arbitrary Python is no longer supported. warning: See http://wiki.xen.org/wiki/PythonInXlConfig Failed to parse config: Invalid argumentThe problem here is that your shell is discarding the quotes; so what xl sees is 'cpus=0-3', not 'cpus="0-3"'. Try the following: # xl -v create hvm-7.0-64-1.cfg cpus=\"0-3\" -GeorgeHi George, Thanks for your hlep. It works with cpus=\"0-3\". Actually, a better way would be to enclose the whole thing in single quotes, and separate variables with a ; like so: # xl -v create hvm.cfg 'cpus="0-3"; memory=2048'This should at very least be documented better -- I'll send a patch to update the xl man page. -George _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
