Fedora35: qemu-kvm opengl is not available

Ask Fedora
1

Hi, I’ve just upgraded my desktop to fedora35 from fedora34, and now my kvm qemu instance won’t start.

# virsh start dave-win10a
error: Failed to start domain 'dave-win10a'
error: internal error: qemu unexpectedly closed the monitor: 2021-11-04T13:21:20.658912Z qemu-kvm: -device virtio-vga-gl,id=video0,max_outputs=1,bus=pci.0,addr=0x2: opengl is not available

I’m really not sure what troubleshooting info to include here. Here is my xml config for this vhost.

I have a bug open on fedora 35 and problems running an f34 VM with qemu on the f35 host.

Your issues may be similar although at least yours is saying something about opengl.

I modified the name of the disk image in my f34 VM, then used that disk image as the basis of a new VM using “Import existing disk image” and created a f35 VM. The VM is now running normally.

Thanks for the tip. I’ll have to go through the VM settings all over again, but at least it’s now running.
