I have a Opensuse 12.2 + Xen 4.2 server.
I want to configure a Xen Guest to boot to a physically attached
Opensuse install DVD, and init the guest with the default 'xl'
toolstack.
The config I'm working with is,
cat ~/os122.cfg
name = 'os122'
builder = 'linux'
bootloader = 'pygrub'
bootargs = '-q'
disk = [ 'phy:/dev/VG0/boot,xvda,w',
'phy:/dev/VG0/swap,xvdb,w', 'phy:/dev/VG0/root,xvdc,w',
'phy:/dev/cdrom,xvdd:cdrom,r',]
root = '/dev/xvdd1'
vif = [ 'bridge=br0',]
vfb = [ 'type=vnc, vncdisplay=01, vnclisten=127.0.0.1' ]
maxmem = 1024
vcpus = 2
localtime = 0
netif = 'yes'
on_shutdown = 'destroy'
on_reboot = 'destroy'
on_crash = 'destroy'
On launch,
xl create -c os122.cfg
Parsing config from os122.cfg
libxl: error:
libxl_bootloader.c:628:bootloader_finished: bootloader
failed - consult logfile /var/log/xen/bootloader.1.log
libxl: error:
libxl_exec.c:118:libxl_report_child_exitstatus:

libxl: error: libxl_create.c:901:domcreate_rebuild_done:

libxl: error:

The referenced log contains,
cat /var/log/xen/bootloader.1.log
Traceback (most recent call last):
File "/usr/bin/pygrub", line 860, in <module>
raise RuntimeError, "Unable to find partition
containing kernel"
RuntimeError: Unable to find partition containing kernel
It appears that pygrub fails to find the kernel in
mount /dev/cdrom /mnt/CDROM
ls -al /mnt/CDROM/boot/x86_64/ | egrep "vmlinuz|initrd"
-r--r--r-- 1 root root 45M Aug 24 08:58 initrd-xen
-r--r--r-- 1 root root 4.2M Aug 24 08:58 vmlinuz-xen
umount /mnt/CDROM
Specifying the kernel & ramdisk path
- bootargs = '-q'
+ bootargs = '-q --kernel=/boot/x86_64/vmlinuz-xen
--ramdisk=/boot/x86_64/initrd-xen'
doesn't help. Same error & log.
What's the correct config to specify the DVD's kernel/init so pygrub can
find it?
