Problems with Xen 4.0.1 pvops on ubuntu 10.10

[wendani]

hi all,

I am now installing Xen 4.0.1 installation on ubuntu 10.10. The installation follows the steps described in https://help.ubuntu.com/community/Xen.

I meet the following errors when booting:

ext3-fs: sda1 cannot mount because of unsupported optional feature (240)


I think it might be the problem on file system format. What shall I configure to turn on EXT4?
I have tried "make linux-2.6-pvops-config CONFIGMODE=menuconfig"

and turned on the following file system support in Xen, but it doesnot work at this moment.

<*> Second extended fs support │ │
│ │
Ext2 extended attributes │ │
│ │
Ext2 POSIX Access Control Lists │ │
│ │
Ext2 Security Labels │ │
│ │
Ext2 execute in place support │ │
│ │ <*> Ext3 journalling file system support │ │
│ │
Default to 'data=ordered' in ext3 │ │
│ │
Ext3 extended attributes │ │
│ │
Ext3 POSIX Access Control Lists │ │
│ │
Ext3 Security Labels
<*> The Extended 4 (ext4) filesystem │ │
│ │
Ext4 extended attributes │ │
│ │
Ext4 POSIX Access Control Lists │ │
│ │
Ext4 Security Labels │ │
│ │
EXT4 debugging support │ │
│ │
JBD (ext3) debugging support │ │
│ │
JBD2 (ext4) debugging support


On the next screen, it gives me another error msg "The disk drive for / is not ready yet or not present"

And if I press S for skip, it finally give me "init: Plymouth main process (947) killed by SEGV signal"
