I would do this a little bit different. Instead of handling virtual
networking yourselve, let libvirt do it for you. I attached
"management.xml" and "storage.xml" livirt virtual networking
definitions. You can enable them like this: "virsh net-define
/path/to/definition.xml". management is in vlan 10, storage in vlan 20.
Start the networks: virsh net-start management, virsh net-start storage.
And let's make them auto-started: virsh net-autostart management, virsh
net-autostart storage. 

Know in your vm definition do the following (virsh edit vm_name):

Example for managment interface:


  
 
  
  
  
  


For storage interface:

Example for storage interface:


  
 
  
  
  
  


You should know have your virtual interfaces in the right network with
the right vlan tag.

Re: [one-users] ubuntu 14.04 as image - no network on first boot

I run into the same problem today and tried to figure out
what could be a way also to included fixed interfaces configured
in /etc/network/interfaces.d.

So, I slightly changed at the end of 00-network (from configure_network on)
== snip ==
configure_network()
{
gen_network_configuration > /etc/network/interfaces
echo "source /etc/network/interfaces.d/*.cfg" >> /etc/network/interfaces
}

deactivate_network()
{
. /etc/os-release
if [ $ID = "ubuntu" ]; then
IFACES=`/sbin/ifquery -la`

for i in $IFACES; do
DEV=`get_dev $i`
/sbin/ifdown $i
done
else
service networking stop
fi
}

activate_network()
{
. /etc/os-release
if [ $ID = "ubuntu" ]; then
IFACES=`/sbin/ifquery -la`

for i in $IFACES; do
DEV=`get_dev $i`
/sbin/ifup $i
done
else
service networking stop
sleep 1
service networking start
fi

sleep 2
}

deactivate_network
configure_network
activate_network
== snip ==

That works fine for me - especially in a mixed setup where I want to
use the context on the one hand, but have the need to configure alias
interfaces on the other hand (which is only handy on a VM with a 
fixed configuration).

What I did not check yet if that influences somehow any other kind of
package (relying on existing interfaces)

Best, Michael

[one-users] Virtual machine vlan tagging

[Neil Schneider]

I'm running OpenNebula in a virtual machine using openvswitch to connect
the machines. I've tried creating a virtual network in libvirt attached to
the  bridge device then attached to it. I tried configuring with the
network interfaces connected directly to the bridge. I keep running into a
problem, where the virtual machine wants to add it's own tag to the
interface. I've been googling 'till I'm blue in the face and I can't seem
to find why vlan tags are getting attached to the devices without me
configuring them and it's ignoring any vlan tags I try to impose. Here's
what ovs-vsctl shows me.

ovs-vsctl show
c6def17d-2cc6-499e-a461-af4fe9aab78a
Bridge management
Port "veth1_one"
tag: 1
Interface "veth1_one"
Port management
Interface management
type: internal
Port "vlan10"
tag: 10
Interface "vlan10"
type: internal
Bridge storage
Port storage
Interface storage
type: internal
Port "vlan20"
tag: 20
Interface "vlan20"
type: internal
Port "veth2_one"
tag: 2
Interface "veth2_one"
Bridge public
Port "vnet0"
Interface "vnet0"
Port "veth3_one"
Interface "veth3_one"
Port "em1"
Interface "em1"
Port public
Interface public
type: internal
ovs_version: "2.1.0"

veth1_one and veth2_one are interfaces on the virtual machine. Notice the
tags. I have that configured no where and I can't seem to find where it's
coming from. Of course it keeps the virtual machines from communicating.
The interface that has no vlan associated with it works as expected. It's
the two other interfaces designated management and storage that I'm having
issues with.

I sure could use some help finding why this is happening. I don't mind
having vlan tags associated, but I want to determine what they are.

Network restart is not supported in ubuntu. There is new code to
overcome this issue but we are still testing the packages. A package
with the latest code is attached if you want to try. You can install
it over the previous version.

[one-users] ubuntu 14.04 as image - no network on first boot

[ML mail]

Hello,

I just generated a KVM qcow2 image for the new Ubuntu Server 14.04 LTS release. 
I usually prepare my images by simply installing the the ONE context package 
(http://dev.opennebula.org/attachments/download/768/one-context_4.5.0.deb) 
which I also did for this image. 


Now when I deploy a VM using this image on the very first boot the network is 
not working, although the /etc/network/interafaces gets correctly setup by the 
ONE context package an "ifconfig eth0" shows no IP addresses assigned to the 
interface. Also a "service networking restart" does not work. The only 
workaround I found for now is to reboot the VM, then networking works correctly.

Is it possible that this is an issue related to the ONE context package? or 
simply some new networking code that Ubuntu 14.04 might have added or modified?

[one-users] create VM window doesn't show template owner and group

Hi,

Create VM window doesn't show template owner and group. As user from 
oneadmin, I can see all of them and that could create security problems 
if some user creates VM template with the same name as system one.


That is true for 4.4 and 4.6.

Re: [one-users] Problem with Appmarket 2.0 RC

[Daniel Molina]

Hi Steve,

I am currently running ruby 1.8.7 (2011-06-30 patchlevel 352)
[x86_64-linux] on CentOS release 6.4 (Final) using rbenv and it is working
perfec. Appmarket is also tested using ruby 1.9.3-p484, so the ruby version
should not be the problem. Maybe there's something wrong in your
environment after all those problems.

If you get the error again after configuring the Appmarket tabs in sunstone
could you check if there is any error in the browser developer console?

Cheers

Re: [one-users] OpenNebula 4.5.85-1 on Ubuntu Trusty Tahr

Hi,

Thanks for taking the time to test it.

We have already created packages for Ubuntu 14.04 and we are now in
the process of testing them. There was no time for RC but they will be
available for the final release.

The changes made are the ones you've described and also changed the
default KVM binary path to /usr/bin/qemu-system-x86_64. Besides that
all is working as before.

Cheers

Re: [one-users] OpenNebula Windows Server 2008 R2.

[Leszek Master]

I've got "VM already contextualized" but if i delete .opennebula file from
C: and rerun this, it works 100% good. So why it doesn't work in the first
time? Any idea how to track this down?

Also how to delete the cd-rom permamently after contextualizing my VM?

Hi Leszek,

have you tried running the context.ps1 manually?

(inside the PowerShell terminal)
d:
Set-ExecutionPolicy unrestricted
Invoke-Expression context.ps1

what happens then?

Hi Thomas,

This addon looks really good! Could you please send the mail again to
the development mailing list [1]? That is the list where we discuss
the new addons and we can continue the conversation there.

I'll be the one in charge of preparing everything, anyway.

Thanks!

[one-users] OpenNebula 4.5.85-1 on Ubuntu Trusty Tahr

[Stefan Kooman]

Hi list,

I've build OpenNebula 4.6 RC (4.5.85) for Ubuntu Trusty Tahr (14.04)
[1]. The package libxmlrpc-c3-dev does not exist any more in Ubuntu
Trusty Tahr (virtual package). I've replaced the requirement in
"control" with "libxmlrpc-core-c3-dev". Besides that
"libxmlrpc-c++8-dev" is also required for building. With those packages
in Build-Depends it builds fine. Besides that I've removed "rubygems" as
a dependency for "ruby-opennebula". Rubygems is included in "ruby" package
in Trusty. I'm testing this build in a vm. So far oned, and sunstone
work. The rest is, as of yet, untested.

@DEVS Are you planning on supporting/releasing OpenNebula 4.6 for Trusty
at OpenNebula 4.6 release time?

Gr. Stefan

[one-users] Megam - Cloud orchestrator for OpenNebula

[Thomas Alrin]

Dear all,
We are proposingMegam - Cloud orchestrator for OpenNebula. Megam 
leverages system configuration framework (Chef http://opscode.com) to 
implement an orchestration engine to launch multiple composite cloud 
application based on templates that are written using ruby code. The 
templates are versioned and can be adopted to every vDC in Opennebula.


Our Roadmap.

Opennebulaoffers basic Cloud management including an intuitive 
self-service interface. It is focused on the level of Infrastructure as 
a Service.


Chefis DevOps software which can interface to OpenNebula and adds 
several features such as lifecycle management for virtual machine images 
and the possibility to deploy standardized middleware and applications. 
These standardized software components provide platform services to the 
application components built on top of them.


Our proposal is to have *Megam* provide cloud orchestration for 
OpenNebula based on open standards like 
TOSCA(http://docs.oasis-open.org/tosca/TOSCA/v1.0/os/TOSCA-v1.0-os.html). Megam 
already provides ability to launch app/services today.  The design 
specifics for TOSCA will be released shortly.


As a first step we are building a  chef plugin to OpenNebula, which can 
stand up instances in OpenNebula using its templates.


Using this knife plugin for OpenNebula, an user can do the following,

* List the templates which are already created in OpenNebula.

* List the VMs which are already created either in OpenNebula or from 
the knife plugin.


* Create a VM by instantiating the OpenNebula template. Chef bootstraps 
the VM and applies a role.


Anxious to hear the communities feedback. Feel free to reach out to us 
(al...@megam.co.in)

[one-users] Problem with Appmarket 2.0 RC

[Steve @ MyEvolve]

Hello Everyone,

I followed the guide to install Appmarket 2.0 RC.  I changed the listen ip
to 0.0.0.0 as instructed and added the specified modifications to the
sunstone view files.

The problem I am getting is that now when I access sunstone its extremely
slow and I never actually get to the main dashboard.  It keeps partially
loading and then reloading.

Even after taking back out the references to appmarket in the sunstone view
config files and restarting sunstone-server and stopping the appmarket
server, I still had very very slow loading of sunstone.

I was only able to correct it by rebooting.

Some background...

I'm using CentOS 6.5 with ruby 1.8.7 and I had to use rbenv to setup ruby
2.1.0 to install Appmarket.  I set it to be applicable system wide and as
the default.

This caused an issue with openflow-server not wanting to start returning an
ruby error which I tracked down as being because of the multiple versions.

I also tried building from source ruby 2.1.0 and using yum remove ruby
thinking that this version was getting in the way.

I then tried to reinstall one 4.6RC and rpm was complaining that ruby
wasn't installed even though it was.

So I've gotten rid of all the above, issued the yum install ruby (and other
ruby items) and reinstalled one 4.6RC successfully using the rpms so I have
my system pretty close to where I started.

So I'm sure that maybe at the heart of this is ruby possibly.  Does anyone
have a good guide on how to install the correct version of ruby on a Centos
6.5 system or any other ideas on how to get Appmarket installed?


Thank you,
Steve

Re: [one-users] easy provisioning doesn't show template owner/group in sunstone

[Ruben S. Montero]

Hi

Using Cloud view, even if a user can access other's template he can only
delete its own templates. Note also that only the VDC admin can share
templates within group. We can think of adding this info to a kind of
extended view but I feel it is no needed

Thanks

Re: [one-users] instance types are sorted by name in new sunstone cloud view

[Ruben S. Montero]

Makes sense, I've filled [1] a issue in dev.opennebula.org. Let see if we
can make it happen before 4.6 Final

Re: [one-users] new sunstone cloud view vs old easy provisioning

[Ruben S. Montero]

Yes Rolandas, that's right. Easy provisioning is now deprecated and the
recommended easy provisioning interface is the new cloud view.


The rationale behind this is:
(1) Combining templates with images may render to non-functional VMs. For
exampla, if you setup OS/ARCH to be 64bits a 64bit Installation is needed.
You may end-up with multiple template containers each for each image type
(2) You cannot combine specific attributes for servers, for example HW
setups or placement options.
(3) It is quite difficult to combine the easy provisioning in 4.4 with
advanced features like hybrid clouds. You need to tie somehow the local
image with the remote AMI. That can only be done at the template level.
(4) Overall, the underlying OpenNebula workflow is based in VM definitions
(templates) so it's easy to expose that at higher levels.
(5) The same templates works both for cloud view and for admin/adv. user
views. No need to create specific templates.

Thanks for the testing and feedback! much appreciated

Ruben

[Ruben S. Montero]

We are fixing some minor bugs in the UI and running the tests. If
everything goes as expected it'll be ready by Friday - Monday next week.

Cheers

Re: [one-users] Multi NIC networking.

[Javier Fontan]

You can set the default value for the network model in the driver
configuration file located at /etc/one/vmm_exec, there is one for each
driver. You can specify it as a NIC option:

NIC = [ model="e1000" ]

Restart OpenNebula server after this change.

[one-users] Upcoming Cloud Technology Days in June in USA (Florida and California)

[Jaime Melis]

Dear all,

in June we will hold two completely free Cloud Technology Days in USA, one
in Boca Ratón, Florida the 19th of June, and the next one in Fremont,
California the 24th of June.

The Cloud Technology Days are events that include a 4 hours hands-on cloud
installation and operation workshop, and presentations from community
members and users that focus on:

- Sharing cloud use cases and deployment experiences
- Introducing new integrations and ecosystem developments
- Describing other related cloud open-source projects and tools

Read more about these two events here:
http://opennebula.org/upcoming-opennebula-cloud-technology-days-in-usa/

Specific information for each event can be found here:
- http://opennebula.org/community/techdays/bocaraton2014/
- http://opennebula.org/community/techdays/bayarea2014/

We still have speaker slots available in both events, and sponsorship
plans. Please contact us if you want to share your experiencies with
OpenNebula, talk about how you have automated your Cloud, about your
Virtualization experiencies, or anything cloudy!

Save the date!!

cheers,
Jaime

The documentation is available on github [1]. You can "fork" the wiki, make
your changes / additions and send a "pull request" to OpenNebula so they
can review and merge your changes.

Re: [one-users] OpenNebula ceph snapshots problem.

[Leszek Master]

I tried to change rbd image version from 1 to 2 but it doesn't work. But
when i changed in my ceph datastore TM_MAD to qcow2 the new VM instantized
from image that was in the datastore stuck on "PENDING". Is there any way
to get this working with "existing" images?
