Installing xen and LVM on Ubuntu 8.04 server

I'm running Ubuntu 8.04 server that I testing out using LVM based xen virtual servers. I opened up the backports in my sources.list, then installed using one of the HowTos "aptitude install ubuntu-xen-server". The install went as it should, then I made my firat test image using:

Code:

xen-create-image --hostname=test1.test.com --lvm=vg0 --size=10Gb --swap=1Gb --ip=192.168.31.231 --force --memory=50Mb --arch=amd64 --debootstrap

After it finishes I use xm create to start the virtual machine but I keep getting:

Code:

Error: (38, 'Function not implemented')

I even tried uninstalling, then reinstalling xen but that didn't help. Has anyone seen this before, or know how to take care of it?

 

Can you post the configuration file of the VM?

 

Code:

# Configuration file for the Xen instance test1.tlthost.net, created
# by xen-tools 3.8 on Sun Mar 28 14:46:54 2010.
#

#
#  Kernel + memory size
#
kernel      = '/boot/vmlinuz-2.6.24-27-xen'
ramdisk     = '/boot/initrd.img-2.6.24-27-xen'
memory      = '50'

#
#  Disk device(s).
#
root        = '/dev/xvda2 ro'
disk        = [
                  'phy:/dev/vg0/test1.tlthost.net-swap,xvda1,w',
                  'phy:/dev/vg0/test1.tlthost.net-disk,xvda2,w',
              ]


#
#  Hostname
#
name        = 'test1.tlthost.net'

#
#  Networking
#
vif         = [ 'ip=192.168.31.231,mac=00:16:3E:52:A0:C9' ]

#
#  Behaviour
#
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

extra = '2 console=xvc0'

 

Looks ok. The only "solution" I could find on the net is to reinstall Xen: http://old.nabble.com/Error-on-xm-create:-VmError:-(38,-'Function-not-implemented')-td21546579.html

 

I actually found that very same article. I already did a aptitude --purge remove, then did the whole install again. I'm going to try an ask the xen people if they know anything. I'm not too hopeful because there are no answers on the web already. I'll post here if I find a fix.
Thanks Falco
