Description of problem:

multi disks indexes in a random order when installing win2008r2

Version-Release number of selected component (if applicable):
qemu-kvm-0.12.1.2-2.171.el6.x86_64
seabios-0.6.1.2-3.el6.x86_64

mostly

Steps to Reproduce:
1.start a win2008r2 installation with multi disks (cmd tooooo long , will attached as a text file)
2.select a disk to install win08r2,after reboot,guest may not continue installation [disks may not the same order as last boot]
3.FYI,all images' size incrementally(storage1.raw == 1G ,storage2.raw == 2G ,etc)
  
Actual results:
disks index  may  not always same when running win2008r2 installer.(see attached pic)
that results installation fail 
Expected results:

Additional info:
if use a pre-installed win2008r2 image , boot with multiple disk,works fine.   4/4
Linux guest works fine when install with multiple disks  2/2

Does windows installation menu shows you all virtio disks? Do you see that same problem with only 5 virtio disks?

Find the min number when it starts to happen.

Hi Gleb,
This bug is funny :) 
   in my tests, it always appear when guest have more that 10 disks.it seems the sequences are in octal. pls see attached octal_index.png

   when boot guest with 3 ~ 10 disk,win guest show me disks in such order
index5..(index6,index7..).... index0,index4 

   ONLY when boot guest with 2 disks,win guest will show the index0 disk as the first disk.

Best Regards,
Xiaoqing.

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 13 RHEL Program Management 2012-07-11 02:00:10 UTC
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.

Funny observation about Win8. We probably can't do anything about it.

After installation, the disks don't appear at different letters. So, it's not a problem.
