Windows Server 2012 Hyper-V; A Smoother VM import process

August 6th, 2012    Posted in Hyper-V, Microsoft Hyper-V, virtualization

Microsoft has made a change to its VM import and export process. On Windows Server 2012 Hyper-V, they have streamlined the VM import process. Those people who have previous experience with import and export process on earlier Hyper-V versions says that they were looking forward to this change.

On previous Hyper-V versions, the VMs had to be exported before importing them. Although this procedure was logical, it always made the process of exporting VMs unnecessarily restrictive.  For instance, if the system drive of a Hyper-V server dies, with the storage array (containing all the virtual machines) is still intact, there is no way for you to replace the drive that failed. Since you did not export the VMs, you cannot import them to another new Hyper-V installation. So, you have to go through a much more involved recovery process.

Another drawback of previous Hyper-V versions was having troubles with importing VM components like VM snapshots, machine configuration file and saved states. In addition, virtual machines always lose their network configuration in the VM import process, due to the method the configuration files reference the virtual network switch.

The renewed VM import procedure

Microsoft is planning to introduce several improvements in Windows Server 2012 Hyper-V to ease the VM import procedure.

However, the most valued change will be the new import wizard. It will not try to blindly import VMs like its predecessors. It is more intelligent. So it will first check for the common problems that usually complicate the VM import, like incompatible hardware or virtual machine paths. While some of the issues are solved by the wizard automatically, some issues would have to be addressed manually. According to the statements by Microsoft, the new wizard will search for and try to solve over forty issues.
