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 -- Cheers, Wenda Ni, Ph.D. Dept. of Computer Science and Engineering State University of New York (SUNY) at Buffalo T: 716 982 6746 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
