Re: [Xen-devel] boot Xen 4.0

[ccmail111 <ccmail111@xxxxxxxxx>]

Thanks Pasi/Todd,

I did:
# mkinitrd -v -f --builtin=ehci-hcd --builtin=ohci-hcd --builtin=uhci-hcd --builtin=ahci --builtin=aacraid --builtin=aacraid --builtin=sd_mod --builtin=scsi_mod /boot/initrd.img-2.6.31.13 2.6.31.13


Now
I see during boot: kernel panic:

Mounting root filesystem.
mount: could not find filesystem '/dev/root'
setting up other filesystems
setting up new root fs
setuproot: moving /dev failed No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
  kernel panic - not syncing : Attempted to kill init !

It doesn't matter.

Wrong. You need to run depmod for the *kernel*, not for xen.

So like this:
depmod -a 2.6.32.12

Or whatever is your kernel version.
