Unable to boot after first sucessful boot of server sles 12U1

Hi ,

I have created one cloud image qcow2 for SLES 12U1 and inbuilt cloud-init too . but strange thing is this it boots sucessfully first time and we can work on it.but when we reboot it says unable to find /dev/sda1 or waiting for device.

I tried to change entries in fstab and grub.cfg with UUID but still same issue.

Please help might me i am nit changing it right but i refered links to do that and same issue.

same kind of thing happening with SLES11U4.
