Description greg matthews 2008-07-11 06:41:47 EDT
Description of problem:
mkrootdev does not create correct root device.


Version-Release number of selected component (if applicable):
RHEL4.6 iso images


How reproducible:
always. 


Steps to Reproduce:
1. boot iso image from SLES10 using Xen
2. install (works fine)
3. boot installed image - get kernel panic:
  
Actual results:
....
SCSI subsystem initialized
Registering block device major 202
Using cfq io scheduler
 xvda: xvda1 xvda2
 xvdb: unknown partition table
device-mapper: 4.5.5-ioctl (2006-12-01) initialised: dm-devel@redhat.com
Kernel panic - not syncing: Attempted to kill init!


Expected results:
switchroot should find correct root partition

Additional info:
by editing the init script within the initrd and changing it to read:

     ....
     mount -o defaults --ro -t ext3 /dev/VolGroup00/LogVol00 /sysroot
     mount -t tmpfs --bind /dev /sysroot/dev
     sleep 5
     echo Switching to new root
     switchroot /sysroot
     sleep 5
     umount /initrd/dev

results in a clean boot.

Comment 2 greg matthews 2008-07-11 07:24:01 EDT
A workaround in the case of RHEL4 domU on SLES10 is to edit /etc/xen/vm/<name>
and add:

extra=" root=/dev/VolGroup00/LogVol00"

Assuming default LVM naming.
Comment 3 Daniel Riek 2008-08-19 13:53:24 EDT
Product Management does not consider this a bug in RHEL4. RHEL5 virt installations give the correct command line.

SLES is not supported as a host.
