Re: [Xen-users] mount: could not find filesystem '/dev/root'

[Ismael <kraziest@xxxxxxxxx>]

That's my grub.conf for this systems:

title Fedora Core (2.6.16.29.fc5xen)
       root (hd0,1)
       kernel /boot/xen-3.0.3-0.gz
       module /boot/vmlinuz-2.6.16.29-xen ro root=LABEL=/1 rhgb quiet
       module /boot/initrd-2.6.16.29-xen.img
title Fedora Core (2.6.16.38.fc5xen)
       root (hd0,1)
       kernel /boot/xen-3.0.4-1.gz
       module /boot/vmlinuz-2.6.16.38-xen ro root=LABEL=/1 rhgb quiet
       module /boot/initrd-2.6.16.38-xen.img
title Fedora Core (2.6.16.38.fc5xen0)
       root (hd0,1)
       kernel /boot/xen-3.0.4-1.gz
       module /boot/vmlinuz-2.6.16.38-xen0 ro root=LABEL=/1 rhgb quiet
       module /boot/initrd-2.6.16.38-xen0.img
title Fedora Core (2.6.16.29.fc5xen0)
       root (hd0,1)
       kernel /boot/xen-3.0.3-0.gz
       module /boot/vmlinuz-2.6.16.29-xen0 ro root=LABEL=/1 rhgb quiet
       module /boot/initrd-2.6.16.29-xen0.img


I tried installing the xen3.0.4, the 3.0.4 dom0 and the 3.0.3 dom0. I
did what you say about initrd (without aacraid option). With both dom0
it can start, but it cannot run the graphical mode and in the logs
appears a "failed to initialize core devices", so I'm begining to
think that I can have a wrong .config. Any suggestion is well
received.

Thanks for answering
