So apparently "linux,dummy-virt" is a devicetree in popular use by various hypervisors, including crosvm: https://github.com/google/crosvm/blob/e5d7a64d377d00b9b96bc026548769ab59cf216b/aarch64/src/fdt.rs#L692 and qemu: https://github.com/qemu/qemu/blob/98c7362b1efe651327385a25874a73e008c6549e/hw/arm/virt.c#L283 and that's because the kernel ships support for that natively: https://www.kernel.org/doc/Documentation/devicetree/bindings/arm/linux%2Cdummy-virt.yaml It's explicitly for using in virtualization. Hence it's suitable for detecting it as generic fallback. This hence adds the check, similar to how we already look for one other qemu-specific devicetree. I ran into this while playing around with the new Pixel "Linux Terminal" app from google which runs a Debian in a crosvm apparently. So far systemd didn't recognize execution in it at all. Let's at least recognize it as VM at all, even if this doesn't recognize it as crosvm.
