Hello,
To compile a custom kernel, I downloaded 2.6.29.1 from kernel.org and
followed the tutorial at:
http://wiki.xensource.com/xenwiki/Kernel.org_Linux_on_Xen
Used a supposedly working .config file for the compilation (generated by
my provider to compile his xenU kernels), set /dev/xvd* device nodes
both in the domU conf file (disk, root):
disk = [ 'phy:/dev/mapper/alveox-fhsslash,/dev/xvdb1,w',
'phy:/dev/mapper/alveox-fhsswap,xvdb2,w' ]
root = "/dev/xvdb1"
and its /etc/fstab:
proc /proc proc defaults 0 0
/dev/xvdb1 / reiserfs defaults 0 1
/dev/xvdb2 none swap sw 0 0
When booting the VM, I get a kernel panic at this point:
...
ReiserFS: xvdb1: found reiserfs format "3.6" with standard journal
ReiserFS: xvdb1: using ordered data mode
ReiserFS: xvdb1: journal params: device xvdb1, size 8192, journal first
block 18, max trans len 1024, max batch 900, max commit age 30, max
trans age 30
ReiserFS: xvdb1: checking transaction log (xvdb1)
ReiserFS: xvdb1: replayed 9 transactions in 1 seconds
ReiserFS: xvdb1: Using r5 hash to sort names
ReiserFS: xvdb1: Removing [190 26878 0x0 SD]..done
ReiserFS: xvdb1: Removing [190 26872 0x0 SD]..done
ReiserFS: xvdb1: Removing [190 26845 0x0 SD]..done
ReiserFS: xvdb1: Removing [190 26804 0x0 SD]..done
ReiserFS: xvdb1: Removing [190 26797 0x0 SD]..done
ReiserFS: xvdb1: There were 5 uncompleted unlinks/truncates. Completed
VFS: Mounted root (reiserfs filesystem) on device 202:17.
Freeing unused kernel memory: 268k freed
Kernel panic - not syncing: No init found. Try passing init= option to
kernel.
Cannot figure why its not booting. It seems to find and mount root
correctly....
When I mount the filesystem manually, /sbin/init appears there.
Tried it with 3 different kernels from kernel.org: 2.6.29.1, 2.6.21.27,
2.6.25.7 --> same error.
Problem does not seem to come from the dom0, when I use the kernel
provided by my provider, the same filesystems are mounted just fine, the
VM boots, here is what I get instead of the kernel panic:
VFS: Mounted root (reiserfs filesystem).
Freeing unused kernel memory: 256k freed
INIT: version 2.86 booting
Any help, or pointers where the problem may come from, appreciated....
Cheers
David
