The first patch modifies creation of the hvmloader key in xenstore and adds creation of a new read/write hvmloader/generation-id-addr key. The second patch changes hvmloader to use the new key (as opposed to the old data/generation-id key). The third patch adds the infrastructure to save and restore the VM generation ID address in xenstore and the code to increment the value.
