[Fedora-xen] Re: 2.6.15-1.1977_FC5hypervisor does not boot (booting is interrupted by restart)

Tue Feb 28 00:11:24 UTC 2006

Hello,

I'm sending an update, based on some advices I have changed my grub.conf:

title Fedora Core (2.6.15-1.1977_FC5hypervisor )
        root (hd0,6)
        kernel /boot/xen.gz-2.6.15-1.1977_FC5 com1=1200,8n1 console=com1,vga
sync_console noreboot
        module /boot/vmlinuz-2.6.15-1.1977_FC5hypervisor ro
root=/dev/VolGroup01/LogVol00 init 3 com1=1200,8n1 console=com1,vga
sync_console noreboot
        module /boot/initrd-2.6.15-1.1977_FC5hypervisor.img

So I have changed speed of display to synchronise with com port to 1200
bauds and noreboot option so I can read last messages.

XEN has loaded fine, but domain0 was not able to mount some drives:

Here are some error messages:
<cut>
Red Hat nash version 5.0.28
Mounting proc filesystem
Mounting sysfs filesystem
Creating /dev
Creating initial device nodes
mknod: failed to create /dev/ram0 file exists    ! first error message I
have noticed
mknod: failed to create /dev/ram1 file exists
<cut>
Creating block device node
Loading jbd.ko module
Loading ext3.ko module
Creating root device
Mounting root filesystem
mount: could not find filesystem /dev/root
Setuproot: mouting /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
<cut>

Do you have any idea where the problem is?
I can provide more detailed log if somebody is interested...
Do you think I should open bugzilla ticket?

Thank you very much for an advice,

Cheers,

Jan
