Hi folks, Ubuntu 8.04 server amd64 - host - headless (w/o X packages) Ubuntu 6.06 server amd64 - guest - headless (w/o X packages) KVM Previously I ran; # qemu-img create -f qcow2 disk.img 10G then # kvm -hda disk.img -cdrom /dev/scd0 -m 512 -boot d to create a working disk.img. It works on the VM. But I couldn't create direct on running; # kvm -hda disk.img -cdrom /dev/scd0 -m 512 -boot d must be in 2 steps. Now I tried creating another disk.img but the above steps did not work. # qemu-img create -f qcow2 ubuntu6.06_080805.img 10G Code: Formatting 'ubuntu6.06_080805.img', fmt=qcow2, size=10485760 kB # kvm -hdb ubuntu6.06_080805.img -cdrom /dev/scd0 -m 512 -boot d -smp 2 Code: =======================| DirectFB 1.0.1 |======================= (c) 2001-2007 The DirectFB Organization (directfb.org) (c) 2000-2004 Convergence (integrated media) GmbH ------------------------------------------------------------ (*) DirectFB/Core: Single Application Core.

I didn't done anything on the host except running apt-get update/upgrade. Please advise. TIA Edit:- I found the cause. It was iptables. After flushing all rules, the problem gone.

From the error message you should be investigating the frame buffer as that is what is causing the failure.
