This patch series adds the ability for a user to specify a tag to be applied to a network interface or a disk when booting an instance. This tag is then exposed through the metadata API. For example, a user boots a VM with two network interfaces. One is connected to a private network, the other to the public Internet. There is currently no direct way to tell which interface is which. Specifying tags allows the user to distinguish between the two interfaces. This patch introduces the new metadata objects.
