Time-out on waiting for label ROOT uuid on ISO boot

[Jan Robinson]

Hello Marcus

Please assist.

Goal: To build a SLES16 version of our MiniOS ISO image we use to install physical servers.

Building the image works 100%
Booting the image with qemu-kv works 100%

Booting the image on hardware fails.
Loading kernel...  all fine
Loading initrd...  problem starts here

During the kiwi-ng build this line is reported with an UUID.

[ INFO    ]: 12:25:11 | --> DEFAULT_APPEND:"splash=verbose rd.kiwi.ramdisk ramdisk_size=4096000 rd.shell rd.kiwi.debug root=UUID=b611ce5b-b0ba-410f-9c54-ec8a80b5fcb0"


In the qemu-kv booted image the UUID is used.
blkid -o json
{
   "label": "ROOT",
   "uuid": "b611ce5b-b0ba-410f-9c54-ec8a80b5fcb0",
   "block_size": "4096",
   "type": "ext4",
   "partlabel": "p.lxroot",
   "partuuid": "167fb5f1-58bc-43a4-b02b-90740cf36e61"
}




Problem:
As I interpret it.

Short:
Timed out waiting for device /dev/disk/by-uuid/b611ce5b-b0ba-410f-9c54-ec8a80b5fcb0
UUID not available

(or press Control-D to continue):

Because the ISO image is booted on a server that already have a SLES installation on it.
This ROOT label's uuid does exist.
