Xen domU not starting - Boot Loader contains no data!

[brunold]

lwelch01,

that error message normally means that the bootloader (/usr/lib/xen/boot/domUloader.py) is not able to extract the kernel and ramdisk from the domU disk (PV_bootloader_args '--entry=xvda1:/boot/vmlinuz-xen,/boot/initrd-xen'). As that is configured to use xvda1 and that is a file based disk, I would check that file.

# fdisk -lu /vmdsk/staff/disk0
...
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0x00088ae9

 Device Boot      Start         End      Blocks   Id  System
disk0p1              63     3309389     1654663+  82  Linux
disk0p2   *     3309390    41929649    19310130   83  Linux

Then calculate the starting of the xvda1 partition by multiplying the start count with the unit size (63 * 512) and mount it in the domU to check the contents:

# mount -o offset=32256 /vmdsk/staff/disk0 /mnt
# ls /mnt/boot

There check if the files /boot/vmlinuz-xen and /boot/initrd-xen exist.
