Can't build ubuntu image. qemu: Error launching VM: Qemu failed to start.

**What happened**:

I can't build ubuntu image for baremetal following instructions

**What you expected to happen**:

To get ubuntu images I can then use on Intel NUCs, (bottlerocket didn't work)

**How to reproduce it (as minimally and precisely as possible)**:

Follow instructions from

You will hit some issues
- with ansible checks use workaround https://github.com/aws/eks-anywhere/issues/5937
- with qemu missing use workaround https://github.com/aws/eks-anywhere/issues/5938

Run
```
image-builder build --os ubuntu --hypervisor baremetal --release-channel 1-26
```

Environment
- Intel NUC (Intel Core i3)
- Ubuntu Desktop 22.10 amd64

Start with the image-builder build command and the Makefile targets at lines 484 and 334 shown in the output. Run the build with PACKER_LOG=1 and review the workarounds in issues 5937 and 5938 to identify why QEMU fails to launch. Done means the Ubuntu baremetal image build completes and produces an artifact.
