many unknown devices in a VM

Question

Server Windows Server 2012 R2 Standard with HyperV.

I virtualized a Windows Server 2012 R2 with Disk2vhd from Sysinternals, created the generation 1 virtual machine and booted but there are many unknown devices.

I installed integration services and did Windows updates but nothing changed.

What can it be?

Thank you

Answer 1

Most likely remnants left over from the conversion. You may be able to remove them but the much cleaner / safer method is to stand up a new one from clean install media, patch fully, migrate roles over and move on.

Answer 2

If I remove them then they come back.

The network card does not work, I had to install the legacy network card.

The mouse doesn't work, I get the message:
"Mouse not captured in Remote Desktop session.
The mouse is available in a Remote Desktop session when integration services are installed in the guest operating system."

Answer 3

These are all the reasons why a P2V should be an absolute last resort. A better option may be to stand up a new one from clean install media, patch fully, migrate roles over and move on. 2008 and newer operating systems have integration services built-in, no need to install.
