I am running QEMU via a shell script. I am not using a desktop environment, just a tiling window manager. Every time I launch a virtual machine, I need to press Ctrl+Alt+M to hide the titlebar.
Per the changelog,
The "-no-frame" option has been removed. It was only usable with SDL1.2, and support for this library has been suspended now.
Note: This is not the same as
#!/bin/sh qemu-system-x86_64 \ -boot d \ -drive format=raw,file=disk.img \ -enable-kvm \ -m 512M \ -net nic -net tap,ifname=tap14,script=no,downscript=no
Note: The rest of the script deals with the setup/teardown of the network interface
tap14; it is not needed here.
