I am also pretty sure if you installed the VirtIO drivers first (if this is possible), you can then migrate the machine. If you can't boot windows to do that, the other alternative is booting VM with Windows ISO attached and VirtIO drivers boot floppy, and in Windows setup there is a way to open the registry of the Windows on the hard disk and tell it to install and load the drivers there.

I am running KVM on Ubuntu 19.10.  The version is 4.0.

I need to get an IDE controller so I can boot the Windows guest on KVM.

IDE isn't an option in virt-manager.

When I try to use an IDE controller from the command line I get an
unsupported error message.  I have tried different machine types as well
(pc vs q35)

How would I get an IDE controller in KVM?



The generic sata controller doesn't work?
Which version of Windows are you using?

Hi Peter.

I am trying to migrate windows server 2008 R2.

No, the generic SATA controller didn't work.

When booting it gives you the BSOD with the 7B error code, which is boot 
drive inaccessible.

To migrate the machine I needed to boot the machine with VirtualBox with 
an IDE controller for the boot disk and an extra sata disk.  That seems 
to get the right SATA drivers installed. Then I can use KVM to boot it 
as a SATA disk.
