I'm interested to hear opinions on whether this makes the code clearer, or not. This is virt-v2v, but many other virt-* tools work the same way, and analogous changes could be made. Currently when command line argument parsing is done in 'cmdline.ml' the list of parsed parameters is passed to the main program in a very long tuple. Each parameter is strongly typed, but not named (so

This series is an attempt to add a mode of virt-v2v operation where it leaves the config and disk image conversion, rollback on errors, registering with the destination hypervisor, etc. to a third-party toolset, and performs only tuning of the guest OS to run in the KVM-based hypervisor.

This series is a second attempt to add a mode of virt-v2v operation where it leaves the config and disk image conversion, rollback on errors, registering with the destination hypervisor, etc. to a third-party toolset, and performs only tuning of the guest OS to run in the KVM-based hypervisor. The first 14 patches are just refactoring and rearrangement of the code, factoring the implementation

A very miscellaneous set of cleanups to how we handle the Windows registry in virt-v2v, firstboot, and inspection code. This should all be straightforward non-controversial refactoring. Some highlights: - Add a new mllib Registry module containing various utility functions that are currently scattered all around. - Only compute the software/system hive paths once during inspection, and
