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)

Hello,
I just generated a KVM qcow2 image for the new Ubuntu Server 14.04 LTS

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?

Re: [one-users] Virtual machine vlan tagging
Quoting Neil Schneider (n...@ifxonline.com): 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. 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: interface type='bridge' mac address='52:54:00:99:7b:d8'/ source network='management' portgroup='vlan10'/ virtualport type='openvswitch' /virtualport model type='virtio'/ address type='pci' domain='0x' bus='0x00' slot='0x03' function='0x0'/ /interface For storage interface: Example for storage interface: interface type='bridge' mac address='52:54:00:99:7b:d9'/ source network='storage' portgroup='vlan20'/ virtualport type='openvswitch' /virtualport model type='virtio'/ address type='pci' domain='0x' bus='0x00' slot='0x03' function='0x0'/ /interface You should know have your virtual interfaces in the right network with the right vlan tag.

[one-users] Re-installing OpenNebula from scratch - just keeping the datastores
Hi, I am thinking of re-installing all of my ONE test installation and at the same time move on from 4.4 to 4.6 as soon as its released. The only thing that I will keep are my NFS datastores which includes VMs and images. Now I was wondering after having setup ONE 4.6 with the same network as the previous one and with the same datastore locations, is it somehow possible to recover my already existing VMs form my NFS datastore? Basically all ONE needs to know is already in the deployment.0 file so in theory it should be able to recover from it? If yes, how do I do that? I am thinking here that this procedure could be especially useful in the scenario when someone loses his whole ONE configuration and the only thing left are his datastores...

Inside the tar.gz that holds the packages there is a source directory [1]. That may be what you are looking for. Context packages are created using a tool called fpm. That may not be a proper way to do it but for that tiny package it seemed OK to me to use it. The files, the script and the documentation on how to create the packages are available in the source repository [2].

[one-users] OpenNebula plus RHEL./Centos/Sci. Linux 6.3 or 6.4
I am wondering if there are any other big OpenNebula clouds out there using RHEL 6.3 or 6.4, Centos 6.3 or 6.4, or Scientific Linux 6.3 or 6.4? We are seeing a fairly nasty performance problem, but only on intel-based Sandy Bridge or Ivy Bridge based hardware. If you have N kvm-based virtual machines running (N=4 as far as I can tell) and then do a lot of disk and I/O activity on the hypervisor, for example migrating several more virtual machines to or from the bare metal, and if at least one of those virtual machines is doing some I/O too, there is a failure mode such that you start seeing sshd processes (from oneadmin monitoring or otherwise) hanging and taking 100% of CPU. Ping times to virtual machines become very widely varied, in extreme cases the VM can even go off the network entirely in such a fashion that ifdown/ifup doesn't bring it back and sometimes you can't even kill it with virsh destroy. A couple times we have even managed to crash the hypervisor irreversibly so it has to be power cycled. If all the surviving virtual machines are shut down, the system then returns to normal and all the hung processes exit. Has anyone else seen problems iike this? If so please let me know. There seems to be little if anything out there about this bug and that is strange since it has been out there for a while.

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

We have tested the package in both 12.04 and 14.04. Network works fine
in the first boot. Did you modify interfaces file after installing the
package? One of the things the package does is to empty the interfaces
file, just has the loopback configured so it does not configure the
network before the context package starts.
checked, yes, that was one reason, I suppose - there was left an entry from
the tests I made (had an older version of the context package before which
modified the interface file also at shutdown, there was no
check if in „start“ or „stop“ phase).
Perhaps this may have been the error?
Another issue was the missing source for files in the interfaces.d directory
(which is needed if you would like to config fixed configurations - or which
sounds to be a way to go in combination with the context package)

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()
{

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)

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?
