Subject [39/50] [abbrv] git commit: refs/heads/events-framework - Summary: add/remove/update default nics feature
Date Thu, 31 Jan 2013 14:22:59 GMT
Summary: add/remove/update default nics feature

Description: Adds API calls updateDefaultNicForVirtualMachine,
addNicToVirtualMachine, and removeNicFromVirtualMachine. These are
intended to allow a user to modify a VM's configuration post
deployment, to adjust the networks to which the VM belongs.
