[Bug 1342000] Comment bridged from LTC Bugzilla
------- Comment From vaish123@xxxxxxxxxx 2014-08-08 06:35 EDT-------
--- Comment from Shawn T Wright ---
I hit this issue on my Unbuntu 14.10 installs as well but noticed it because I was attempting to install an iso from a VIRTIO-SCSI CD-ROM device.
[[!!]] Detect and Mount CD-ROM
Your installation CD-ROM couldn't be mounted.....
I also tried the same thing for VIRTIO-Block CD-ROM and it failed the
same way.
I then tried PAPR-SCSI CD-ROM and it works, but then it comes up and I
hit the issue described in this defect that no drives were detected. My
Drives are configured for virtio-scsi.
???????????????????????????? [!] Detect disks ?????????????????????????????

? No disk drive was detected. If you know the name of the driver needed ?
? by your disk drive, you can select it from the list. ?

This issue is very simple to recreate and can be done 100% of the time.
This is blocking tests.
Whats the target date / build that we will see the fix for this issue
in?

HI,
Yes this is reproducible every time. And here in xml , used entire
disk which is divided into LUNS ( raw whole disk) and hence did not
used qemu image.

Indira

I too encounter the same output as mentioned in this defect
When I tried the same with same xml and ubuntu build 14.04 it worked
fine. The disks were listed and I was able to proceed with
installation.
