Looking into the logs ,this error will come if someone is using some external media (ex :USB stick ).Suppose it is /dev/sda and our hard disk is /dev/sdb .. then installation should occur on /dev/sdb, but it is trying to install on /dev/sda.. so workaround is to remove external media and continue. 

But, here they are doing virtual dvd install on LPAR.

Gave up waiting for root device.  Common problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
   - Check root= (did the system wait for the right device?)
 - Missing modules (cat /proc/modules; ls /dev)

Can you try to recreate this problem with today's daily build.
