My LVM Volume : AnOnLVDeb isn''t partioned. The file system is ext3, and yes i can mount /dev/AnOnVG/AnOnLVDeb in my dom0 When i tried to call hda instead of hda1 in my config file, i''ve got the same error, exept the last line : VFS: Unable to mount root fs on unknown-block(3,0) Unknown-block is now 3,0 instead of 3,1 On Nov 25, 2007 5:15 PM, Chris Cameron <chris@soniplex.com> wrote:> Is your lvm volume partitioned?

I solved my problem : It was a pb with initrd. I just add the line : ramdisk = "/boot/initrd.img-2.6.18-5-xen-686" on my domain.cfg On Nov 25, 2007 8:44 PM, AnOnJoe <anonjoe@gmail.com> wrote:> My LVM Volume : AnOnLVDeb isn''t partioned. > The file system is ext3, and yes i can mount /dev/AnOnVG/AnOnLVDeb in my > dom0 > When i tried to call hda instead of hda1 in my config file, i''ve got the > same error, exept the last line : > VFS: Unable to mount root fs on unknown-block(3,0) > Unknown-block is now 3,0 instead of 3,1 > > > > > On Nov 25, 2007 5:15 PM, Chris Cameron <chris@soniplex.com > wrote: > > > Is your lvm volume partitioned?
