633	No filesystem could mount root  during restore	Victor	Bruno Cornec	"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'.
