The physical memory address bits that are reported to the guest OS. Should be smaller or equal to the host's. Set to 'host' to use value from host CPU, but note that doing so will break live migration to CPUs with other values.

The VM generation ID (vmgenid) device exposes a 128-bit integer value identifier to the guest OS. This allows to notify the guest operating system when the virtual machine is executed with a different configuration (e.g. snapshot execution or creation from a template). The guest operating system notices the change, and is then able to react as appropriate by marking its copies of distributed databases as dirty, re-initializing its random number generator, etc.
Note that auto-creation only works when done through API/CLI create or update methods, but not when manually editing the config file.
