Hello I still have a problem with our OBS Appliance. But I have come a little further. I now know that if I try this:

/usr/bin/qemu-kvm -no-reboot -nographic -vga none -net none -cpu host -kernel /boot/vmlinuz -initrd /boot/initrd -append root=/dev/sda panic=1 quiet no-kvmclock nmi_watchdog=0 rw rd.driver.pre=binfmt_misc elevator=noop console=ttyS0 init=/.build/build -m 256 -drive file=/var/cache/obs/worker/root_8/root,if=none,id=disk,serial=0,cache=unsafe -device ide-hd,drive=disk -drive file=/var/cache/obs/worker/root_8.swap,if=none,id=swap,serial=1,cache=unsafe -device ide-hd,drive=swap -smp 1

I get to this point [ 0.075731] NET: Registered protocol family 2 [ 0.076112] TCP established hash table entries: 2048 (order: 3, 32768 bytes) [ 0.076611] TCP bind hash table entries: 2048 (order: 3, 32768 bytes) [ 0.077067] TCP: Hash tables configured (established 2048 bind 2048) [ 0.077514] TCP: reno registered [ 0.077749] UDP hash table entries: 256 (order: 1, 8192 bytes) [ 0.078164] UDP-Lite hash table entries: 256 (order: 1, 8192 bytes) [ 0.078626] NET: Registered protocol family 1 [ 0.078948] pci 0000:00:00.0: Limiting direct PCI/PCI transfers [ 0.079369] pci 0000:00:01.0: PIIX3: Enabling Passive Release [ 0.079776] pci 0000:00:01.0: Activating ISA DMA hang workarounds [ 0.080249] Unpacking initramfs... and qemu-kvm thread stalls for 8.5 hours and then terminates.

But if I bump the command up to use -m 512 instead I get passed this but get this: [ 0.374929] Waiting for device /dev/sda1 to settle... [ 2.377787] Waiting for device /dev/sda1 to settle...

Can anyone help me on from this point because this is actually the only blockade for me now (I hope).

So, the block device does not appear. You may use a initrd which has not the proper kernel modules for kvm?

Our appliance does configure by default the following modules for the initrd, at least the virtio and used filesystem modules are critical:

loop dm-mod dm-snapshot binfmt-misc fuse kqemu squashfs ext2 ext3 ext4 reiserfs nf_conntrack_ipv6 binfmt_misc virtio_pci virtio_blk fat vfat nls_cp437 nls_iso8859-1
