[Xen-users] Xen on EC2 | Debian Squeeze AMD 64

[Xavier Cardil <xavier@xxxxxxxx>]

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):

  File "/usr/lib/xen-default/bin/xend", line 38, in <module>

    from xen.xend.server import SrvDaemon

    import relocate

  File "/usr/lib/xen-4.0/lib/python/xen/xend/image.py", line 46, 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)')

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 !
