The VM will start, one core will be at 100%, but no display from the HDMI. There is zero disk I/O happening.
The process goes like this: boot the odroid, get odroid splash screen, linux bootloader visible on screen starts linux, display then says "Starting version 246.1-1-arch" then no more output on monitor. When I start the VM from ssh, the screen goes blank and the monitor says "connect cable". In the QEMU ssh session I tell it to boot the ISO, it gets to the point where it selects the install option but then nothing happens and the VM just sits, burning a core at 100%.
