Hi Anne If I modify the flavor, the vm doesn't take effect immediately. So how can i add more cpu to a running instance?

You can read more at http://docs.openstack.org/trunk/openstack-ops/content/flavors.html. It indicates that you can use nova flavor-create -- note that you're technically not modifying an existing flavor, you're creating a new flavor and renaming it. Use nova --debug flavor-create to see the API commands associated with these adjustments to flavors. 2) enlarge a disk to an instance This is also specified in flavors. 3) get the information about ram/cpu/disk size of an instance You want this I believe. http://api.openstack.org/api-ref.html#ext-os-flavorextradata Thanksfrom Peter _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack at lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp -------------- next part -------------- An HTML attachment was scrubbed...
