Importing VMs From external Hyper-V Hosts

I've been working on a project where I needed to migrate (clone actually, in order to maintain a fallback scenario) virtual machines from external (standalone) Hyper-V hosts to a Hyper-V cluster. The external hypervisors were not members of the same domain as the cluster nodes. The networks were separated by a firewall. A trust relationship between the domains was not desired.

System Center Virtual Machine Manager 2012 (SCVMM) supports this scenario, but there are several steps that must be performed to prepare for the migration.

Loop-mount VirtualBox Disk Images

A Wrapper Class for Active Directory Queries

Tired of writing the same boilerplate code for querying objects from Active Directory over and over again? So am I.

See API documentation for details.

Linker Errors When Building Xlock on Debian

When building xlockmore (version 5.39) on one of my Debian boxes I encountered two linker issues, one with libxext, the other with libcrypt. Both issues persisted even after running configure with the --without-ext and --without-crypt options. WTF?! Why would anyone with at least half a brain provide --without-FEATURE options for apparently required features?
