OK, now I made it past the network issue, but the VM still will not run. 
Looks to be some storage problem?

Everything in /var/lib/one is owned by the oneadmin user thus read write 
should be OK.

The path /var/lib/one/datastores/1/3118ec2b9f3c9e9d3df0a42363ca72c8 does 
exist. This file has the same size of the disk image file I installed, 
i.e. suse-12.1-SUSENebula-guest.x86_64-1.0.0.qcow2. The permissions of 
/var/lib/one/datastores/1/3118ec2b9f3c9e9d3df0a42363ca72c8 are 640 owner 
is oneadmin and the group is cloud.

The configuration file for the datastore is as follows:

-> cat testVM.dsconf
NAME   = "openSUSE test image store"
DS_MAD = fs
TM_MAD = qcow2

The VM is setup as follows:

/usr/bin/onedatastore create testVM.dsconf
/usr/bin/oneimage create testVM.one -d 1
# System needs time to copy the image
sleep 15
/usr/bin/onevm create testVM.vmd

With these configuration files:

-> cat testVM.one
NAME = "openSUSE test image"
PATH = "/home/ctester/suse-12.1-SUSENebula-guest.x86_64-1.0.0.qcow2"
PUBLIC = YES
DESCRIPTION = "A test image to test the basic functionality of the 
openSUSE based OpenNebula setup"


-> cat -> cat testVM.vmd
NAME   = suse-test
MEMORY = 512
CPU    = 1

OS     = [ ARCH = x86_64,
            BOOT = hd,
            ROOT = sda1 ]

DISK   = [ IMAGE_ID  = 0,
            DRIVER    = qcow2 ]

NIC    = [ MAC = "00:16:3e:7e:18:26",
            BRIDGE = br0 ]

GRAPHICS = [ TYPE   = "vnc",
              LISTEN = "0.0.0.0",
              PORT   = "5905" ]


Help is appreciated.

Thanks,
Robert
