Bug Description

Just launched the Maverick Server amd64 Daily ISO today in a KVM (on an amd64 maverick host), with virtio disks.

The server installer complained about not seeing any disks.

Dropping to the shell, I confirmed that /dev/vda was not there, as I expected that it should have been.

Checking lsmod, I see the virtio modules loaded.

I don't have much more information for now, but it's easy to reproduce, and this is a beta blocker, I think.

Filed against both kernel and debian-installer. I'm not quite sure where the bug is, but hopefully the people watching those two packages will be able to triage it appropriately.

My vm was launched through testdrive with the following command line:

kvm -m 1024 -smp 2 -cdrom /home/kirkland/.cache/testdrive/iso/ubuntu_maverick-server-amd64.iso -drive file=/home/kirkland/.cache/testdrive/img/testdrive-disk-qKihPq.img,if=virtio,cache=writeback,index=0,boot=on -usb -usbdevice tablet -net nic,model=virtio -net user -soundhw es1370 -vga cirrus

Confirmed, I get the same behavior with

kvm -cdrom ubuntu_maverick-server-amd64.iso -boot d -drive /srv/serge/vms/lucid-delme.img,if=virtio,index=0 -m 512M

This happened because somebody inappropriately removed (at least some of) the -17 kernel udebs while d-i was still built against them. The latter was because I had the temerity to be on holiday for a day. Shame on me.

I've uploaded d-i built against -19, and this should sort it out.
