Hi Canonical,
Per the attached syslog, the installation fails because the the scsi device representing the virtual dvd does not get mapped. The setup on the PowerVM side of things looks correct. Note that this is a regression from 16.04.

Hi Pooja,
Just to say we tried the latest daily build, please retest using a newer iso from:
http://cdimage.ubuntu.com/ubuntu-server/daily/current/

The image I downloaded today, Sept 23 around 1pm eastern daylight (GMT-4) has a 4.8.0-14 kernel. Please attach a syslog to this bug from the daily build that you test.

Thanks, Gary

[Steve Langasek (vorlon)]

This will be related to the landing of Linux 4.8 and various driver reorganizations happening at the same time.

[Steve Langasek (vorlon)]

Right, since this was with a daily image using 4.8.0-11, it's quite possible this has already been fixed in a later image build and is worth a re-check.

[Leann Ogasawara (leannogasawara)]

I'd suggest to retest with the 4.8.0-16 kernel, once it's respun into an image for testing. I'll try to drop a note here when I see that is available, which should hopefully be shortly.

[Leann Ogasawara (leannogasawara)]

We've had a few respins, but if you could test the following, feedback would be appreciated:
