Well, I have tried to replicate it using the described scenario on 83-based version of Xen user-space tools and I have never seen this message.

Then I tried:
 1. xm create FVguest when device has been added as sda device to config file
 2. inGuest> dmesg -> no trace of error message about SCSI
 3. inGuest> ls /dev/sda* -> there is /dev/sda device (not partitioned yet)
 4. inGuest> fdisk -l -> no valid partition on /dev/sda
 5. inGuest> fdisk /dev/sda & created new partition, written using 'w' option
 6. inGuest> dmesg -> still no error message about SCSI

Could you tell me how to reproduce the problem and/or try to reproduce it using my RPMs at http://people.redhat.com/minovotn/xen ?

Thanks,
Michal

Hi.Michal
   I can not reproduce the issue in xen-3.0.3-80.el5_3.2 and your rpms now... ( the ia64 box is re-installed. and now works well.)

Comment 3 Michal Novotny 2009-06-03 08:46:46 UTC

Hi,
ok, so should I close it now if this is not the issue ? What reason?

Michal

Comment 4 Michal Novotny 2009-06-03 12:11:16 UTC

Ok, closing it. If this is still an issue please reopen it... thanks, Michal
