There seemed to be a problem with the NFS share as it didn't mount
correctly when the node restarts.
Although it doesn't mount correctly, the dir structure is still
available showing an old file structure.
I've to figure out how to correctly add it to fstab. At the moment it
throws an error at start up and I have to mount it manually.
With the correct mount I was able to start up ttylinux (status 'runn')
but I couldn't connect (no IP, no ssh possibility). Looking in a qemu
window, the ttylinux image throws disk errors continuously and is not
really able to start up completely. I think some kind of incompatibility
between the server settings/config where the image was created and my node.
Therefore I will try to create an ubuntu image with virt-builder to see
if that will work.
If I run into new issues I will post them in a new thread.
Thanks so far,
Mike

Can't see the test file ...
What action could I take ?

Don't do that, the disk.0 that is written in the deployment file is
the actual disk copied by the TM. It seems that you are using tm_nfs
but the shared storage is not mounted in the correct path in the
remote node. Try creating a file in /srv/cloud/one/var and check if
you can see it in the remote host in the same path.

Got some progress here:
qemu: could not open disk image /srv/cloud/one/var//8/images/disk.0: No
such file or directory
Indeed: the XML file is called deployment.0
Don't know why it created the file as disk.0 ...
Moreover, I could get the image running directly in the node by invoking:
virsh --connect qemu:///system create deployment.0
Domain one-8 created from deployment.0
(off course after editting the deployment.0 file changing disk.0 to
deployment.0)
So, it seems it's possible to get it going. Now I have to figure out how
to
teach OpenNebula to create a proper deployment file !
Where is this file generated ?

Probably the problem is the support for virtualization. To be sure you

I restarted the host machine before deployment of the VM, so VM
services
should be initiated.
BTW: I found out that the host CPU has no support for the
virtualization
instruction set required by KVM. Can it be the cause of the above
failure ?
Or should KVM revert automatically to another state to continue
deployment ?
I'm glad to provide more output from logs if necessary.
