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

[You, Yongkang]

It seemed Xen0 couldn’t find root filesystem in your root=/dev/VolGroup01/LogVol00

 

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

 

 

 

Best Regards,

Yongkang (Kangkang) 永康

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

mknod: failed to create /dev/ram0 file exists    ! first error message I have noticed

<cut>

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

Hello everybody,

This is my first e-mail into this mailing list. I have a problem to start
2.6.15-1.1977_FC5hypervisor kernel (domain0).

When I select this option in a grub I can see that xen hypervisor is loading but after
short time my laptop is restarted. 
I cannot tell you last (error) message because pause or CTRL+S does not work and laptop is
restarted before drives are mounted so I have no logs. 
Do you have any idea where is the problem and how can I pause booting so I can see last
(error) message? 

Other details: I have Dell latitude D600 with Pentium M. I have upgraded FC4 to FC5 test3
using DVD iso. I have updated all packages after that using yum update. 
Kernel 2.6.15-1.1977_FC5 works fine on my laptop. I was also able to start domain0 in FC4
using kernel from Rik van Riel's web page ( 2.6.12-1.1454_FC4).

Some other problems I found:
When I upgraded from FC4 to FC5 test3 I did not see any option to install XEN from DVD (I
have selected upgrade not new install in anaconda). 
Also entries for FC4 kernel were deleted from my grub.conf and original grub.conf was not
saved.
When I have installed kernel 1977_FC5 or 1977_FC5hypervisor my grub.conf was not updated,
so I had to update it manually (I have used yum install). 

Part of my grub.conf configuration (manually added) - do you see any problem here?
