Description Marco Sinhoreli 2007-07-17 23:54:30 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.4) Gecko/20070508 Iceweasel/2.0.0.4 (Debian-2.0.0.4-0etch1)

Description of problem:
When I boot the virtual machine rhel4 guest with 'xm create -c /etc/xen/astronomix-baraddur1.cfg' command, return "Kernel panic - not syncing: Attempted to kill init!" as the URL with the problem demonstration. Using a kernel non-Red Hat for guest rhel4, the Virtual Machine boot work.

Version-Release number of selected component (if applicable):
xen-3.0.3-25.0.3.el5

How reproducible:
Always


Steps to Reproduce:
1. Edit the Virtual Machine conffile as below:
# /etc/xen/astronomix-baraddur1.cfg
name ='astronomix-baraddur1'
disk = ['phy:/dev/baraddur1/astronomix,hda1,w', 'phy:/dev/baraddur1/astronomix-swap,hda2,w']
memory = 1024
builder = 'linux'
kernel = '/boot/vmlinuz-2.6.18-8.1.8.el5xen'
#kernel = '/boot/vmlinuz-2.6.18-4-xen-amd64'
ramdisk = '/boot/initrd-2.6.18-8.1.8.el5xen.img'
#ramdisk = '/boot/initrd.img-2.6.18-4-xen-amd64'
root = '/dev/hda1 ro'
vif = ['bridge=xenbr4, vifname=astronomix-baraddur1-0']
#vcpus = "7
#cpus = "1"
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'

2. To create lvm disks with a rhel4 OS installed.

3. Boot the virtual machine with the command below:
xm create -c /etc/xen/astronomix-baraddur1.cfg


Actual Results:
The Virtual Machine with official rhel5 kernel not work.

Expected Results:
Virtual Machine boot complete.

I'm not entirely clear on what the problem is.  Are you saying that you can't
boot a RHEL-5 PV guest, or that you can't boot a RHEL-4 PV guest?  In either
case, please provide the complete dmesg output from the guest and
/var/log/xen/xend.log and /var/log/xen/xend-debug.log.

Thanks,
Chris Lalancette

Haven't heard back on this problem in a year; closing with INSUFFICIENT_DATA.  If the problem occurs again, feel free to re-open.
