Can't boot: UUID does not match

[Kévin Poirot]

I installed CoreOS from Qemu (my only way to install OS on my dedicated server). So in rescue mode (Ubuntu 12 launched via PXE), I launched Qemu :

qemu-system-x86_64 -no-kvm -hda /dev/sda -cdrom linux-live-cd-with-kernel-3-14.iso -boot d -vnc :0

Then I launched the install script :

./coreos-install -d /dev/sda -C stable -c cloud-config.yaml

Now, when I use Qemu, everything works fine

qemu-system-x86_64 -no-kvm -hda /dev/sda -boot d -vnc :0

but when I reboot the server to directly start on CoreOS, I get some errors and the system won't boot

Warning: /dev/disk/by-label/ROOT does not exist
Warning: /dev/disk/bypartuuid/7130c94a-213a-4e5a-8e26-6ccce9662f132 does not exist
Warning: /dev/disk/bypartuuid/e03dd35c-7c2d-4a47-b3fe-27f15780a57c does not exist

With another OS, I would modify /etc/fstab with correct UUID but CoreOS/Systemd seems to automatically generate fstab on each boot.

How can I resolve this boot problem ?

Thanks in advance.

Hm, perhaps we do not include the driver for your disk controller.
Could you post the output of 'lspci -nn' when booting from your rescue
mode or the CoreOS ISO?

I added a screenshot for the output from Qemu.

Yup, the driver for that controller is not currently enabled in our kernels:

# CONFIG_PATA_VIA is not set

Will look into adding that soon but for now you'll have to stick with
QEMU I suppose.
