I'm not sure if this is the right place to ask... I'm attempting to boot OSTree: https://live.gnome.org/OSTree/GnomeOSTree ...using the QEMU method. It works on Fedora using this command line: qemu-kvm -vga vmware -cpu core2duo -M pc-0.15 -kernel /boot/vmlinuz-$(uname -r) -initrd /boot/initramfs-ostree-$(uname -r).img -hda ostree-qemu.img -m 1024M -vga vmware -append 'rd.plymouth=0 root=/dev/sda ostree=current ' -monitor stdio I'd prefer to get it running on openSUSE so I can take it on my laptop. It fails with this error: (qemu) Could not initialize SDL(No available video device) - exiting Is there an easy way to diagnose this?

Are you remotely logged into a system using ssh? You would need to use ssh -X ... If that's not the issue, check the value of the DISPLAY environment variable. That needs to be valid.

I've used 'sudo -i' to log in as root in a terminal window. Root access is required by the disk image.

I'm using DISPLAY=:0.0 ... is that correct? Thanks, Mike -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-virtual+owner@opensuse.org

I don't claim to be an expert on security, so I won't comment on the security implications here, but I was able to get qemu-kvm to use SDL by exporting both the DISPLAY and XAUTHORITY that is set in your session before doing a sudo -i, within that session. ie: sudo -i export DISPLAY=:0.0 export XAUTHORITY=<whatever it was set to before sudo> qemu-kvm ... Hopefully this helps. Bruce -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-virtual+owner@opensuse.org

Yeah, it's recommended not to run the test setup where security is a concern.

Terrific, Bruce, thanks! I'll give it a try. Mike -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-virtual+owner@opensuse.org

Hey Bruce, adding the two to the Defaults line in /etc/sudoers did the trick! Thanks again, Mike -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-virtual+owner@opensuse.org
