Hi, I confirm that I can still reproduce this in wheezy using debirf 0.32. Using debirf 0.33 (only package that was updated when testing; same machine), it works fine both using the minimal.tgz example from debirf 0.32, and the one from debirf 0.33. I've uploaded the broken image to http://blop.info/pub/vmlinuz-3.2.0-3-amd64 http://blop.info/pub/debirf-minimal_wheezy_3.2.0-3-amd64.cgz To reproduce, boot with kvm -m 512 -kernel vmlinuz-3.2.0-3-amd64 -initrd debirf-minimal_wheezy_3.2.0-3-amd64.cgz I just downloaded your two files and did the kvm command that you provided and I did not get the segfault, rather it booted up to this: /proc/cmdline: No such file or directory Debian GNU/Linux wheezy/sid (none) tty1 (none) login: but otherwise, I do not get the segfault that you experience. The only difference here is that I was running in Squeeze. Unfortunately, I could not find a wheezy box with amd64 and kvm extensions. I'll ask around to see what I can find. If I remember correctly, it segfaults during boot, but then continues to boot and still displays the login prompt. However you cannot log in.

The only difference here is that I was running in Squeeze. Unfortunately, I could not find a wheezy box with amd64 and kvm extensions. I'll ask around to see what I can find. And that you did! I downloaded the given images, and started them up with KVM: kvm -m 512 -kernel vmlinuz-3.2.0-3-amd64 -initrd debirf-minimal_wheezy_3.2.0-3-amd64.cgz I am running: qemu-kvm1.1.2+dfsg-2 linux-image-3.2.0-3-amd 3.2.23-1 This is an up to date wheezy machine. I have rebuilt my own debirf image on wheezy too, just to make sure, so using debirf 0.32, i did: tar zxf /usr/share/doc/debirf/example-profiles/minimal.tgz debirf make minimal ... as a regular user. I arrive to similar results: I do not see a segfault, but then I can't login to the virtual machine either.
