[Xen-devel] Booting Failures when using linux-2.6.33.2 as DomU with paravirt-ops support
Hello, everyone! I am trying to boot linux-2.6.33.2 as DomU'' kernel in my virtualization platform (Xen-3.4.2, linux-2.6.18.8 as Dom0, paravirtualization, AMD Opteron 2216, CentOS 5.3 without virtualization support). But it is always core-dump when booting. The messages are as follows: Loading aic79xx.ko module Loading sata_nv.ko module Creating root device. Mounting root filesystem. mount: could not find filesystem ''/dev/root'' Setting up other filesystems. Setting up new root fs setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init!

So I really do not know why the experiment always fails. Could somebody help me with this? Thank you very much for your help!

Re: [Xen-devel] Booting Failures when using linux-2.6.33.2 as DomUwith paravirt-ops support
Hello, Konrad!
Thank you very much for your reply.
Firstly, I select following config options as "y" when compling
linux-2.6.33.2:
CONFIG_PARAVIRT_GUEST=y
CONFIG_XEN=y
CONFIG_HVC_DRIVER=y
CONFIG_HVC_XEN=y
CONFIG_XEN_BLKDEV_FRONTEND=y
CONFIG_XEN_NETDEV_FRONTEND=y
Secondly, I also select CONFIG_XEN_FBDEV_FRONTEND and
CONFIG_XEN_KBDDEV_FRONTEND as "y",
and it also core-dumps when booting.
Finally, the whole output is list as follows:

Re: [Xen-devel] Booting Failures when using linux-2.6.33.2 asDomUwith paravirt-ops support
Hello, Konrad:
Thank you very much for your help!
There is not any partitions on /sda3/vmdisk2. I creat it using the following
bash script:
dd if=/dev/zero of=vmdisk2 bs=4096 count=1310720
mkfs -t ext3 vmdisk2
mount -o loop vmdisk2 /mnt
rsync -aH /{var,root,dev,etc,usr,bin,sbin,lib,lib64,home} /mnt
mkdir /mnt/{proc,sys,tmp,mnt}
sync
umount /mnt
I am sure that it will work, because when I use linux-2.6.18.8 (download from
http://www.xen.org/ )
as DomU's kernel, the VM can boot sucessfully. The guest configuration file
is the same except the
following two lines:
kernel = "/boot/vmlinuz-2.6.18.8-xenU"
ramdisk = "/boot/initrd-2.6.18.8-xenU.img"
The whole output when booting is list as follows:
[root@node18 sda3]# xm cre -c zxxm2
Using config file "./zxxm2".

Kernel 2.6.18.8-xenU on an x86_64
node182 login:
It aslo has the output: " xvda: unknown partition table", but it can
boot up sucessfully. When
I login and run "fdisk -l", the whole output is as follows:
[root@node182 ~]# fdisk -l
Disk /dev/xvda: 9663 MB, 9663676416 bytes
255 heads, 63 sectors/track, 1174 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/xvda doesn't contain a valid partition table
However, the VM can work normally. So I do not think it is the partitions cause
the problem.
I am sure that I select these following config options as "y" when
compling linux-2.6.33.2:
CONFIG_EXT2_FS=y
CONFIG_EXT3_FS=y
CONFIG_EXT3_FS_XATTR=y
I do not use any logical volumes, so I do not need to use LVM name when writing
the guest
configuration file. In linux-2.6.33.2, CONFIG_DM_LINEAR does not exist. Thus I
select the
corresponding one as "y", which named CONFIG_BLK_DEV_DM. However, it
also does not work,
and the output is the same.
It is really a difficult problem for me. Thank you again for your help!

It sees the disk, but no partitions on it. How did you see up
your /sda3/vmdisk2? Are there partitions on it? Did you make sure to
build the kernel with the filesystem support for this (ext2, ext3,
ext4?) Or do you have logical volumes? If so, you need to make
the root option (in you guest configuration file) use your LVM
name, not the disk name. Also this requires turning on the
CONFIG_DM_LINEAR option.

Thank you again for your help!I believe you are hitting in the problem that your initrd was created with older tools (say RHEL5 ones) which expect a certain SysFS layout. The new kernels have a different one and require this options to be turned on: CONFIG_SYSFS_DEPRECATED_V2=y _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello, Konrad! I select CONFIG_SYSFS_DEPRECATED_V2=y as you said when compiling linux-2.6.33.2, and the VM boots up sucessfully. Thank you very much for your help!
