Hi Javier,
thanks for your hint. I copied again the entires from ~/.ssh/
known_hosts to /etc/ssh/known_hosts,
and checked that the frontend can connect to itself. Now the scp
command works.
After the deploy command with "onevm deploy" the state of my VM is in
"prolog", and fail some minutes later with following error (in
oned.log):

my vm.template looks like:
---
NAME = vm1
CPU = 0.5
MEMORY = 128
OS = [
kernel = "/boot/initrd.img-2.6.27-14-server",
initrd = "/boot/initrd.img-2.6.27-14-server",
root = "hda" ]
DISK = [
source = "/var/lib/one/images/disk0.qcow2",
target = "hda",
readonly = "no" ]
NIC = [ NETWORK = "Public VLAN" ]
---
Does anyone know what i am doing wrong? Where can i look also for log-
information except for the "oned.log"?
Is my VM image not compatible (I builded it with vmbuilder)? It is no
problem to launch this image within "virsh" from command line
on a Linux-Desktop.
Are there any example VMs available I can use for testing?
Thanks for your help!
