When importing a virtual machine to Hyper-V R2 you might see the following error dialog:
Importing the virtual machine succeeded but with the following warning.Import completed with warnings.
I have seen this error quite a bit, and I must say that it is no reason for panic. Your VM is safe.
If you open the error and read the detail, you will see what really went wrong. (Click on that See details down arrow).Well, psyche. That details box is rarely helpful – it simply points you to the proper event log- then you being digging.
Each time I have seen this error the repair has been the same. Simply open the settings of the virtual machine and connect the virtual NIC to the proper virtual network switch.Also, each time I have seen this the leading events have been the same. I created the Export from Hyper-V v1 and I am importing to Hyper-V R2.
