Microsoft Windows Server 2008 Hyper-V has been out for several months now. Several people have started to implement Hyper-V on some level, which has spawned several support calls to Microsoft support. The people over at the AskCore blog put together a “Top Issues” list as well as resolutions. Here are some of the categories and issues:

Deployment\Planning

• How to migrate virtual machines from Virtual Server 2005 to Hyper-V

Installation Issues

• After the Hyper-V role is installed, a virtual machine fails to start with the following error:
  The virtual machine could not be started because the hypervisor is not running

Virtual Machine State and Settings

• When you attempt to create or start a virtual machine, you receive the following error:
  The requested operation cannot be performed on a file with a user-mapped section open. (0×800704C8)

High Availability (Failover Clustering)

• Virtual machine settings that are changed on one node in a Failover Cluster are not present when the VM is moved to another node

Hyper-V Snapshots

• Snapshots associated with a VM are lost.
