Xen image creation problem

[goolee]

hi friends,,
i hav used the HOWTO in this link http://www.howtoforge.com/installing...tu-8.10-x86_64..

However i get the following error when i type "xm create /etc/xen/xen1.example.com.cfg"

ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
Traceback (most recent call last):
File "/usr/sbin/xm", line 8, in <module>
from xen.xm import main
File "/usr/lib/python2.5/site-packages/xen/xm/main.py", line 61, in <module>
xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')

i hope i shall get the problem here.

Did you boot into the Xen kernel? It seems as if Xen is not running.

What's the output of

uname -a

?

but here i wantd to ask a question..
when i follwed thta "HOW TO" ..it prompted me to install Xen thro internet and i did ..How ever when i rebooted the computer..there was no xen on grub..instead there was "UBUNTU server" on my ubuntu 8.10 desktop computer..

Thanks

Hey..here is the output
pls have a look at the attachment

That's the normal Ubuntu kernel which cannot be used for a Xen dom0.

What's the output of

ls -la /boot

, and what's in /boot/grub/menu.lst?

There's an initrd.img for kernel 2.6.27, but no vmlinuz or config file for that kernel which makes me believe it wasn't installed properly. Did you see any errors during the installation of that kernel?

What's in /boot/grub/menu.lst?

# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 3

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
hiddenmenu

# Pretty colours

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing

## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=c75d72a6-cf6f-41fe-9460-3adff864aa21 ro

## should update-grub create alternative automagic boot options
## e.g. alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash

## should update-grub lock old automagic boot options

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

## should update-grub create memtest86 boot option

# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false

## should update-grub add savedefault to the default options

No signs of a Xen kernel. There must have gone something wrong when you tried to build the kernel.
