Hi Andrew, I use the below .sh start script for Debian on armhf, network works fine last time I tried it. You can modify inside the virtual disk if you mount it as a nbd loop device, I seem to remember if I did it your way it was read-only, but that was year ago. I used it to change the root password to no password at all when I forgot it....

Hi Andrew,

I use the below .sh start script for Debian on armhf, network works fine last time I tried it.

Thanks, it seems to use same -device virtio-net-device so may be fedora need some additional actions inside vm... You can modify inside the virtual disk if

you mount it as a nbd loop device, I seem to remember if I did it your way it was read-only, but that was year ago. I used it to change the root password to no password at all when I forgot it....

Hi Andrew, I got it to work almost first time inclusive network. Key was the extra kernel cmd line option you gave: rootflags=subvol=/root . Because the only user on the system is root, which is disabled for login, I tried your init=/bin/bash , but that did not work . So I manually added a user to /etc/passwd, /etc/shadow, /etc/group (and made the user member of group "wheel" to be able to do sudo), I copied the user entries for those files from the host system. Reboot (> 5 minutes), login, and it complains about /home/<user> missing. As sudo, easily corrected. The VM was very busy, "top" showed coredumps and backtraces being generated, Xorg was crashing. "Sudo systemctl disable lightdm", then "Sudo systemctl stop lightdm" . Eventually system activity died down, and it is was reasonably fast. I added file /etc/modules-load.d/modules.conf, and put virtio_gpu in there. After reboot, Xorg still crashes, so more to be done. virtio_gpu is the recommended (by qemu) video for machine "virt" . On Debian_armhf, I also see (lsmod) drm modules loaded, but on Fedora with modprobe no success, and on Debian Xorg does not work either :-) I prefer SSH over the startup terminal, because Ctrl-C in the latter kills the VM. That only happened to me 100 times or so :-) Below is my current startup script: ===== #!/bin/bash Disk=/home/mat/Qemu/Fedora36_armhf/Fedora-Xfce-36-1.5.armhfp.qcow2 Version=5.17.5-300.fc36.armv7hl qemu-system-arm \ -machine virt \ -m 4096 \ -cpu cortex-a15 \ -smp cpus=8,maxcpus=8 \ -append "root=/dev/vda3 console=ttyAMA0 earlyprintk=ttyAMA0 console=tty1 rootflags=subvol=/root" \ -kernel ./vmlinuz-$Version \ -initrd ./initramfs-$Version.img \ -device virtio-blk-device,drive=hd0 \ -drive file=$Disk,if=none,format=qcow2,id=hd0,discard=unmap,detect-zeroes=unmap \ -serial stdio \ -netdev user,id=n0,hostfwd=tcp::10122-:22 \ -device virtio-net-device,netdev=n0 \ -device virtio-rng-pci \ -device virtio-gpu-pci -display sdl =====
