this is in my domU config file for that host:

kernel  = '/boot/vmlinuz-2.6.26-2-xen-amd64'
ramdisk = '/boot/initrd.img-2.6.26-2-xen-amd64'

memory = 2048
name = "shibidp1"
ipadres = "157.193.42.29"
vcpus = 1
disk = ["phy:xenvg/shibidp1,sda,w"]
execfile("/xen/config/xenmachine.py")

(I have attached the xenmachine.py script)

Maybe some more information, because I was misunderstood.

I have create an lvm volume on my dom0 and have exported that volume  
as sda to my domU.  I want to install that domU with FAI.

I don't understand why this worked with my old fai (setup_harddisks).   
And with setup-storage it doesn't.

I understand that example is to be used for installing dom0's.  Right?

Anyway:

Using config file: /var/lib/fai/config/disk_config/SHIBBOLETH_IDP
Input was:
disk_config sda virtual
primary /boot       200       ext3    rw createopts="-L boot"
primary swap        2048      swap    sw createopts="-L swap"
primary /           6000-      ext3    rw createopts="-L root"
(CMD) parted -s /dev/sda unit TiB print 1> /tmp/KV0IPRnvL2 2> /tmp/kF7tT2dyVN
Executing: parted -s /dev/sda unit TiB print
Command parted -s /dev/sda unit TiB print had exit code 1
INTERNAL ERROR in setup-storage:

I hope Henning can be of assistance...

Thanks in advance,
