Hi all. In CentOS 5 with kernel 2.6.18-8.1.4.el5xen and a file-backed
disk, I am unable to successfully boot Debian Etch. It basically
stops doing anything after loading cron, but right before it would
normally spawn a login process. Note that the same domU file was
copied from a working Debian system which does not exhibit this issue.
Config looks like this:
kernel = "/boot/vmlinuz-2.6.18-8.1.4.el5xen"
ramdisk = "/boot/initrd-xencustom.img"
memory = 192
name = "roffle"
disk = ['file:/home/roffle.img,sda1,w']
root = "/dev/sda1 ro"
extra = "4"
Note the custom initrd because using the included initrd does not seem
to furnish a scsi controller, thus I get "mount: could not find
filesystem '/dev/root'" if I try booting up on the stock initrd.
Another thing I notice is that it seems to boot up much slower than on
the Debian system, which is odd because the Debian system is only a
P4. I also tried a 'yum update' to bring me up to kernel
2.6.18-8.1.6.el5xen - no luck with this kernel either, both with the
included initrd (which still does not work like the previous kernel
version), or by making my own initrd. Note that the same problem
occurs in a Debian Sarge image as well. Needless to say, i've tried
many many iterations and config scenarios trying to get this to work.
In both cases (Sarge and Etch), I have created the image using the
normal 'dd ; mkfs.ext3 ; debootstrap' method. Most recently I also
noticed there were things about SELinux in the domU kernel output on
the CentOS system, so I disabled it by adding 'selinux=0' to the
kernel parameters, still no change.
For reference, the command I'm using to create the initrd is 'mkinitrd
-f --with=ext3 --preload=ext3 --with=xennet --preload=xenblk
/boot/initrd-xencustom.img (kernelversion)'. Also for reference, the
hardware config on this box is Core2Duo 2.13, Western Digital 120GB
IDE drive and 2GB DDR SDRAM on an Asus P5GL-MX.
Am I missing something? Full kernel/boot output from the CentOS domU
(with selinux=0) below.
Regards,
Andrew Wang
