Ubuntu 17.04 installation with "Guided - use entire disk and set up LVM" fails

---Problem Description---
Ubuntu 17.04 Guided - use entire disk and set up LVM and Guided - use entire disk and set up encrypted LVM does not create separate partition for /boot and so fails to complete the installation.

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.
