Hi,<div><br></div>Your 1st problem might be related to the qemu dynamic_ownership configuration, check the kvm configuration guide [1] for more details.<div><br><div>About the automatic IP assignment, you need to contextualize your VMs so they can configure the IP leased by OpenNebula, see [2] for more information.</div>

Good day,<br>
<br>
<br>
I’m performing an initial deployment of OpenNebula 3.2 (same issues<br>
persist on 2.2, 3.0 as well) and having several challenges:<br>
<br>
The environment:<br>
<br>
<br>
Ubuntu 11.10 server (front-end + compute nodes)<br>
<br>
ONE 3.2 built from source<br>
<br>
Installed as per instructions on OpenNebula.org for v3.2.<br>
<br>
QEMU is running as user oneadmin and group cloud.<br>
<br>
1. A VM can be deployed using a template I create and .raw disk<br>
image uploaded as an image. The VM enters the RUNNING state, however<br>
issues exist when attempting to stop the image. It seems that<br>
there’s permissions missing somewhere.<br>
<br>
2. Automatic assignment of hostname + network address does not<br>
work. Although, when the VM is in RUNNING state an IP address is<br>
properly leased out to the instance from the available pool, it is not<br>
configured on the instance. VM NIC is configured for DHCP<br>
assignment.<br>
