  No this was done after the code freeze, and not request by a partner
as a feature for RHEL-5, so this is not present.

Yes currentMemory will be in. This should not be a big problem, you can generate
the XML with it, and if the library don't understand it, it should just ignore
it.
The set of patches are the following:

Patch0: create_message.patch   -> bug fix
Patch1: libvirt-0.1.8-shreable-disk.patch -> shareable disk
Patch2: localization.patch -> localization
Patch3: core_dump.patch    -> support for domain core dump
Patch4: current_memory.patch -> current memory amount support
Patch5: bootloader.patch   -> bug fix for pygrub bootloader
Patch6: python-lock.patch  -> release python lock when calling libvirt
Patch7: ostype.patch       -> os type bug fix
Patch8: vcpu_info.patch    -> bug fix
Patch9: pvfb.patch         -> Paravirt frame buffer support
Patch10: pvfb2.patch
