hanging process with commit 69562648f9 ("vl: revert behaviour for -display none")

[Sebastian Ott]

Hej,

qemu fails to start a guest using the following command (the process just
hangs): qemu-system-aarch64 -machine virt -cpu host -smp 4 -m 8192 
-kernel /boot/vmlinuz-6.7.0-rc1 -initrd ~/basic.img -append "root=/dev/ram 
console=ttyAMA0" -enable-kvm -device virtio-gpu,hostmem=2G -display none

..which I've used to debug a potential virtio-gpu issue. Bisect points to
69562648f9 ("vl: revert behaviour for -display none")

Is that qemu cmd just invalid and shouldn't have worked in the first
place?

Sebastian
