Here are permissions for the image and for the base image:
-rw-r--r-- 1 oneadmin cloud 262144 2011-01-20 19:23 qcow.img
-rw-r--r-- 1 oneadmin cloud 2147483648 2010-11-19 12:22 ubuntu10-04.img
...and for the folders (/srv/cloud/temp and up):
drwxr-xr-x 3 oneadmin cloud 4096 2011-01-24 14:32 .
drwxr-xr-x 12 oneadmin cloud 4096 2011-01-18 12:01 ..
These are the permissions for disk.0 before it is deleted due to failure:
-rw-rw-rw- 1 oneadmin cloud 262144 2011-01-24 14:45 disk.0
Any thoughts?

Is /srv/cloud/temp/ubuntu10-04/qcow.img readable by root? It needs to
be readable by root in the execution node. Also check the permissions
in for the directories where it is stored.
tm_clone.sh should have changed permissions for
"/srv/cloud/one/var//24/images/disk.0" check if that is correct. root
is the user that is accessing these files but with NFS sharing you
have to give the permissions for all or add no_root_squash to the
exporting parameters.

I created a qcow2 image from a raw image like this:

The DISC section of of my deployment descriptor looks like this:
DISK = [
source = "/srv/cloud/temp/ubuntu10-04/qcow.img",
target = "sda",
readonly = "no" ,
DRIVER = qcow2]
I have edited the ~/lib/tm_commands/nfs/th_clone.sh file according to this
https://support.opennebula.pro/entries/348847-using-qcow-images without the
SSH part:

Unfortunately deployment fails and this is what I find in the one-*.log
files in the /var/log/libvirt/qemu folder of a target host.

Deployment of raw images works fine. The version of ON is 2.0.1.
I was wondering, whether there is some chmod operation that has to be added
to the tm_clone.sh script or is the problem in something else?
