VBScript arrays can be created with fixed or dynamic size. Fixed size arrays are rather straightforward. Define Dim var(4) and you have an array variable var with 5 elements (indexes 0 through 4). Unfortunately dynamic arrays aren't quite as simple.

Creating blank VMs for PXE boot

For a customer project I had to create a couple dozen virtual machines on our Hyper-V cluster. The machines were to be installed via a 3rd party software deployment system (the customer doesn't use SCCM), so I had to assign static MAC addresses and enable PXE boot. The respective reservations on the DHCP server had to be created from the MAC addresses in a second step, because the customer domain is separated from the infrastructure domain.

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.
