Anyone tried to install Flatcar/UMH on QEMU/KVM? I wanted to give it a try, following the instructions on https://umh.docs.umh.app/docs/production-guide/installation/flatcar-installation/ . Works fine for a start but it never gets past the point where the prompt says core@flatcar-0-install. It should continue installing and finally reboot, but nothing happens, no CPU load and no processes working on anything interesting. Any clues?
