Hi Liam,

Certainly not trying to waste anyone's time. Appreciate your thoughts.

I am trying to use a RP-4 computer module system.  I took the rasp img put
on the micro sd card and the booted in the hardware.

I "desired" to emulate that image on my x86 host - virt-manager did not
seem to boot it. I was "hoping" to emulate the system - and setup teh DISK
image like a want/need and so I can just copy the image to and SD cards as
I need.

I downloaded olivers suggested image - and that boots in virt-manager - but
have not had a chance to "try" that on the SD card if it will actually run
on RP-4 compute module.

I was just thinking that the Rasp image  I started with would emulate on
virt-manager - surprised it does not.

Thanks all - I have more micro SD cards on order - will try the other image
then.

Jerry
