QEMU installation is broken

Question

I am trying to run a Windows 10 VM on Windows 10.

What I did

I downloaded QEMU exe, then got Windows Installation Media to get the Windows 10 iso file. Then I simply moved to the Windows 10.iso file into the QEMU installation folder. Then renamed the Windows 10 iso file to "win10.iso".

Then I ran these commands in the command prompt

qemu-img.exe create -f qcow2 -o cluster_size=2M win10.qcow2 50G

qemu-system-x86_64.exe -boot d -cdrom win10.iso -m 2048 win10.qcow2

What happened

But after running the second one, it gave me this error (the QEMU window popped up though):

C:\Users\Zack\Downloads\QEMU>qemu-system-x86_64.exe -boot d -cdrom win10.iso -m 2048 win10.qcow2
qemu-system-x86_64.exe: warning: GdkPixbuf: Cannot open pixbuf loader module file 'C:\Users\Zack\Downloads\QEMU\lib\gdk-pixbuf-2.0\2.10.0\loaders.cache': No such file or directory

This likely means that your installation is broken.
Try running the command
  gdk-pixbuf-query-loaders > C:\Users\Zack\Downloads\QEMU\lib\gdk-pixbuf-2.0\2.10.0\loaders.cache
to make things work again for the time being.

How do I fix this? Thanks.

Answer 1

I had the same issue with qemu installed via scoop.

To get rid of the warning, just create an empty file loaders.cache, i.e.,

C:\Users\Zack\Downloads\QEMU\lib\gdk-pixbuf-2.0\2.10.0\loaders.cache

in your case.
