I believe adding the below line should also fix it.  I run CentOS 4.2 as
well and use this line instead of the fastboot.

root = "/dev/sda1 ro"

Subject: [Xen-users] xen and boot problems (with CentOS 4.2)

Hello --

We're trying to get a Centos 4.2 system working under a Centos 4.2
operating system using the instructions we found at
http://mark.foster.cc/wiki/index.php/Centos-4_on_Xen.  The prospect of
running several virtual servers on one physical box is pretty
intriguing.  I think we're pretty close, but we've gotten to a place
that has me stumped.  I'm hoping someone can help.

We've gotten to a place where we can actually boot our VM by running
'xm create -c /etc/xen/vm03 vmid=3' (we are using the configuration from
the Xen documentation).  We see the standard kernel boot
up messages and things start out well.  Then we get to:

EXT2-fs warning (device sdb3): ext2_fill_super: mounting ext3 filesystem
as ext2

VFS: Mounted root (ext2 filesystem).
Freeing unused kernel memory: 184k freed
unix: no version for "struct_module" found: kernel tainted.

/dev/sdb3 is mounted.  e2fsck: Cannot continue, aborting.


*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Press enter for maintenance
(or type Control-D to continue):

I cannot for the life of me figure out what's going wrong.  I've
dropped into the maintenance shell and done a fsck, but as soon as I
try to boot it back up again, the same problem.

Thank you for any help.
