Public bug reported:

Binary package hint: qemu

I attempted to install ubuntu jeos 7.10 in Qemu (Ubuntu 7.10 x86-64,
qemu  0.9.0), but the installation would fail when the text based
install program attempted to detect a (virtual) CD-ROM drive. The error
message was:

Detect and mount CD-ROM
No common CD-ROM drive was detected.

The message went on to suggest loading drivers from floppy, selecting a
drive model manually, etc. Manually selecting any of the suggested CD-
ROM drivers made no difference (all failed).

The command line used was:

qemu -hda Jeos-7.10 -cdrom ubuntu-7.10-jeos-i386.iso -m 512 -boot d

The file used for qemu (Jeos-7.10 in the example above) was created by
means of:

dd of=ubuntu-test_7.10-jeos bs=1024 seek=4194304 count=0


The test was repeated with other Ubuntu versions (all x86-32) with the 
following results:

1) 7.10 jeos - (described above - failed).
2) 7.10 desktop - installed OK.
3) 7.10 server - failed (as above).
4) 7.04 server - installed OK.
5) 6.10 server - installed OK.


The tests for 6.10 server and 7.10 jeos were repeated on a 386 (Via processor 
running Ubuntu 7.10) with the same results  as above (6.10 server installed, 
while 7.10 jeos did not). All tests were conducted using an image file (iso) as 
the install source, not a physical CD drive. 

The key points to note are that the desktop version of 7.10 installs OK,
but server or jeos for version 7.10 using the text based installer fail.
Also 6.10 or 7.04 server will install, but 7.10 server (or jeos) fails.
This seems to suggest the problem may be related to there being a
different version of the text based installer in version 7.10.

This may be related to bug #120316, but that one described it as a
problem detecting the actual physical drive, whereas the problem
reported here is happening with an image file (I did not test this with
an image on a physical CD). Furthermore, the comments in #120316
reported problems with both desktop and alternate, whereas I am not
seeing any problems with desktop (I did not test alternate). One comment
in #120316 reported "ata_piix.blacklist=yes" as a boot option fixed the
problem. I tried that, but it made no difference in the problem being
reported here. These factors suggest this might not be the same thing as
#120316.
