Hello ! I''m trying to run Xen on a EC2 AMI
debian-6.0-squeeze-base-x86_64-20110417 (ami-35b68141)
Following this how-to
http://www.howtoforge.com/paravirtualization-with-xen-4.0-on-debian-squeeze-amd64
After installing the packages, I get :
uname -a
Linux ip-10-241-22-60 2.6.32-5-xen-amd64 #1 SMP Tue Mar 8 00:01:30 UTC 2011
x86_64 GNU/Linux
uname -r
2.6.32-5-xen-amd64
Then I do : mv /etc/grub.d/10_linux /etc/grub.d/50_linux
update-grub2
*
*
*
*
After I reboot but I get this when calling xm :
xm dmesg
WARING! Can''t find version 3.4 of xen utils, fallback to default
version!
Error: Unable to connect to xend: No such file or directory. Is xend
running?
When I execute xend I get :
xend
WARING! Can''t find version 3.4 of xen utils, fallback to default
version!
ERROR Internal error: Could not obtain handle on privileged command
interface (2 = No such file or directory)
Traceback (most recent call last):

<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)'')
Does this has to do with the kernel I''m booting ?
My /boot looks like this :
System.map-2.6.32-5-xen-amd64
initrd.img-2.6.32-5-xen-amd64
config-2.6.32-5-xen-amd64
vmlinuz-2.6.32-5-xen-amd64
grub
xen-4.0-amd64.gz
And my menu.lst looks like this :
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
#
### BEGIN /etc/grub.d/40_custom ###
default 0
timeout 1
title 2.6.32-5-xen-amd64
root (hd0)
kernel /boot/vmlinuz-2.6.32-5-xen-amd64 root=/dev/xvda1 ro
initrd /boot/initrd.img-2.6.32-5-xen-amd64
### END /etc/grub.d/40_custom ###
I have been trying to get around this but ... nothing works !
Any help would be much appreciated, thanks in advance !

I may be wrong, but I''m fairly sure you''re not supposed to run xen in a vm. I believe amazon uses xen for ec2, so you''re basically trying to run xen as a vm under xen.

From my experience with squeeze, this sounds like it isn''t loading the qemu-dm portion. Can you post a copy of your /boot/grub/grub.cfg?

Xavier,
Yours looks considerably different from mine :
menuentry ''Debian GNU/Linux, with Linux 2.6.32-5-xen-amd64 and XEN
4.0-amd64'' --class debian --class gnu-linux --class gnu --class os
--class
xen {
insmod lvm
insmod part_msdos
insmod part_msdos
insmod ext2
set root=''(vg-sys)''
search --no-floppy --fs-uuid --set bf38b210-e546-45d5-b10d-722f6743761b
echo ''Loading Linux 2.6.32-5-xen-amd64 ...''
multiboot /boot/xen-4.0-amd64.gz placeholder
module /boot/vmlinuz-2.6.32-5-xen-amd64 placeholder
root=/dev/mapper/vg-sys ro quiet
echo ''Loading initial ramdisk ...''
module /boot/initrd.img-2.6.32-5-xen-amd64
}
I don''t know if it''s from a different version or grub(I am
running grub2)
or if your grub isn''t picking up the other kernel options when
update-grub
is run. I would look into those areas first.
I am also wondering if it might be a issue attributed to running this off
of a already virtualized set up from Amazon. I would look through your
logs to see if there are any error messages about unsupported cpu or other
hardware.
I am unfortunately running into the limits of my experience with this. I
have two physical servers currently running squeeze and Xen and are working
pretty good, but I am also looking at transitioning to a different distro
because of a few things that the older kernels from Debian just are not
able to provide.
Something I had to learn early on posting on this list, and still have
issues remembering. This list doesn''t provide the list itself as the
sender, just the person that posted or replied. Please use reply-all so
that all of the correspondence can be posted to the archive so that if
someone in the future is searching out a similar problem the will have that
to use as a resource.
Thank you.
Shane
