Hi Jon,
thanks for your feedback! it really helps us. I'll separate each topic in
different messages, so we can continue separate sub-threads per topic
1) OVS
So, it's normal that you got this error:
[TemplateInstantiate] Error allocating a new virtual machine. Cannot get
IP/MAC lease from virtual network 0.
if no LEASES where defined. An empty network is similar to a network where
all the leases are taken, so this is expected behaviour.
However, the other error message is a bit more worrying. It looks like
there is a bug. The bit of code that's failing is this one [1], the port
method. Apparently the dump-ports command is failing. Could you do the
following right after the VM has been started?
sudo ovs-ofctl dump-ports ovsbr0 vnet1
and see what happens?

Hello All,
I've just installed OpenNebula 3.9.80 and I have to say this is
amazing. Everything works so smoothly.
Anyway, down to business.
OpenVSwitch:
I've installed and configured OpenVSwitch and am able to manually add
the OVS config using libvirt, then launch a VM,
interface type='bridge'
source bridge='ovsbr0'/
virtualport type='openvswitch'
/virtualport
model type='virtio'/
address type='pci' domain='0x' bus='0x00' slot='0x05'
function='0x0'/
/interface
Which creates the device in ovs:
system@ovsbr0:
lookups: hit:1346333 missed:46007 lost:0
flows: 8
port 0: ovsbr0 (internal)
port 1: eth0
port 2: br0 (internal)
port 7: vnet0
However, when I attempt to create a virtual network without assigning
an IP and instantiate the template I get the error:
[TemplateInstantiate] Error allocating a new virtual machine. Cannot
get IP/MAC lease from virtual network 0.
The template of the virtual network is:
oneadmin@loki:~$ onevnet show testnet1

If I add an IP to the vnet, I get the following template and error
logs (full vm log attached, I think I've identified the relevant
line):

I attempted to run the command but I never set a password for the
oneadmin user, but I don't think it's a permissions / sudo access
problem.
Not really sure where to look next. Any ideas are appreciated.
CEPH:
I'm trying to use a Ceph datastore with a RBD instead of a cephFS
(it's an option).
When I try to create a Ceph datastore with a RBD type, I get a state
of Error,
but I'm not sure where to look for relevant logs, oned.log didn't seem
to have anything,
or maybe I'm just grepping for the wrong string.
As a work around, I have been creating the directory, creating the rbd
then manually mounting it,
this seems to work in my test environment, but doesn't seem very
scalable, how are others using CEPH?
Documentation:
I've noticed some errors in the documentation, namely the location of
the install scripts,
The docs state they are in:
