No filesystem could mount root during restore

[Victor]

I am trying to restore a RedHat6.2 image created by mondorescue(3.0.1). During PXE network boot, I got following error:

List of all partitions: No filesystem could mount root, tried: iso9660 kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(1,0) Pid: 1, comm: swapper Not tainted 2.6.32-220.el6.x86_64 #1 Call Trace:

I basically followed README.pxe.

It works fine with RedHat5.

During mondoarchive, I noticed "Disk /dev/mapper/vg_dcvops01-lv_root doesn't contain a valid partition table" poped up, which showed up on 'fdisk -l'.

[Redhat 6.2]# fdisk -l
