Tips: Adding roles to 2008?

Need to add a role to 2008? Use ServerManagerCmd. If you’re running Server Core, use ocsetup. On a related note, Ben has a good post on installing Hyper-V in a core configuration.

Windows 2008 with Hyper-V: The hypervisor is not running?

Trialing Hyper-V on Windows 2008, but not able to get your guest instances to fire-up? If you’re running an HPDL380 G5 for instance, and you’re getting an error message to the effect of “The virtual machine could not be started because the hypervisor is not running”, and you’ve already flashed your BIOS, and made sure to enable hardware virtualization, and it’s still happening – make sure DEP (data execution prevention) is enabled in the BIOS too. On the DL380, this lives in the BIOS under Advanced>Processor Options>No-Execute Memory. After you power down, and power it back up (don’t just do a soft reset), you should be able to start your guest instances.
