Re: [one-users] newbie how-to configure network to connect to the vm
Hello Nikolaj, I think the problem is that your AR uses a wrong network prefix. virbr0 is configured with 192.168.122.0/24 prefix and your definition in the AR is IP = 192.168.0.100.

Re: [one-users] hardware requirements
Hello Cyrill, When you say hardware requirements are you referring to the OpenNebula frontend node and/or compute nodes? The best answer I can find is 'it depends' :). I have a couple of OpenNebula deployments in the wild and I will tell you what kind of hardware I use. Most probably others have different configurations. 16GB RAM, Intel Quad Core CPU, 1 TB Storage space - Frontend 16GB RAM, Intel Quad Core CPU, 1 TB Storage space - Compute Node 32GB RAM, Intel Quad Core CPU, 2 TB Storage space - Frontend 32GB RAM, Intel Quad Core CPU, 2 TB Storage space - Compute Node 24GB RAM, Intel Quad Core CPU, 2 TB Storage space - Frontend 24GB RAM, Intel Quad Core CPU, 2 TB Storage space - Compute Node I don't make the Frontend a compute node also because it also has SaltStack Master installed and I don't want the services on the Frontend node to be slow because of virtual workload on top of them. I think it depends on what kind of services you plan to run on top of your Cloud when you choose the hardware configuration.

Re: [one-users] BOOTPROTO, DHCP_HOSTNAME, and vm IPs in Sunstone
Hello Kerry, I am unsure how to use a DHCP client to suggest an IP to the DHCP server, or if DHCP supports this. The DHCP client can be configured to request a specific IP address from the DHCP server [1].

To add that parameters to network configuration you can do one of these things: * Create the network configuration in the base images manually and do not set network contextualization in OpenNebula so they are not overwritten. * Modify the context packages to add those parameters [1] For the third thing there is no way to do it. OpenNebula gets an IP from the network pool and assigns it to the NIC. There is no way to change it after it is selected and there is no external method of selecting the IP. What you can do is configure DHCP so it picks the same IP as OpenNebula had selected for the VM. The MAC addresses are generated from the MAC prefix and the IP, you can configure DHCP with those mac/ip pairs.

Re: [one-users] DHCP
Hello Kerry, When you say DNS and DHCP are tied into one system on my network you mean your DNS server is configured with a dynamic zone that is updated from the DHCP server? If that is so, I guess you want a VM to acquire a lease from the DHCP server equal to the IP given by OpenNebula to that specific VM. This way it maintains consistency. If you populate CONTEXT with NETWORK=YES, the contextualization packages will do the job of configuring the network. As far as I know it's not possible to tell the contextualization packages to leave the network unconfigured. So using this approach would not get you where you want. One way of achieving what you desire is to program a hook that inserts a host in the DHCP server via OMAPI [1]. From the hook you have access to the entire template. I am assuming you are using ISC DHCP. This would solve the consistency issue. Now the VM needs to be configured for DHCP as you mentioned in your previous E-Mail. For that you can define SET_HOSTNAME in the CONTEXT to have it available in the VM, create a simple (bash) program that reads it and sets ifcfg-eth0 accordingly. Put the script in the files datastore and update the context to use it via FILES_DS and INIT_SCRIPTS. For example you name your super script set_dhcp.sh. You can insert in the files datastore [2] using `oneimage create -d files --name set_dhcp.sh --type CONTEXT /path/to/set_dhcp.sh`. Update the template to use it. CONTEXT=[ FILES_DS=$FILE[IMAGE=\set_dhcp.sh\, INIT_SCRIPTS=set_dhcp.sh] This way the vmcontext init.d script from the contextualization packages would skip the network configuration, note NETWORK=YES is missing and it would run the set_dhcp.sh script. One more thing that comes to mind, SET_HOSTNAME would instruct the vmcontext init script to set the hostname and maybe that's not what you want, maybe you want your VM to set it's hostname from DHCP. In this case use another variable, like DHCP_HOSTNAME in CONTEXT and process it in set_dhcp.sh to configure ifcfg-eth0. You can set DHCP_HOSTNAME=$NAME inside the template. This way the name you give the VM in Sunstone would end up being used. Take the above with a grain of salt, I am sure there are other (better) ways of achieving what you desire. @Diego could you please point me where have you find DHCP in the VNET template? I have looked over the docs and couldn't find it.

Re: [one-users] OVH (So You Start) + OpenNebula + 1 IP
Hello Pablo, On Fri, Jul 18, 2014 at 6:53 AM, Pablo Hinojosa Nava pablo...@gmail.com wrote: Hi all, I am having problems trying to set up an OpenNebula host to virtualize with KVM. I have bought a dedicated server with OVH (So You Start) with 1 publlc IP. The public IP is on eth0 interface and each time I try to create a Linux bridge (as is suggested during the installation http://docs.opennebula.org/4.6/design_and_installation/quick_starts/qs_ubuntu_kvm.html#configure-the-network ) I got frozen the SSH connection. If I edit the file /etc/network/interfaces, then I run /etc/init.d/networking restart and it seems the server does not do anything. If I restart the server with changes made, I cannot recover the connection and I have to reinstall the operating system. If I try to create the bridge by hand, I the same problem (connection lost) when I try to add the bridge to the public network interface (etc0). It seems OVH use Mac Filtering switches, so that could be the reason. I could buy a block of 8 or 16 IPs, but it does not change way to configure OpenNebula. If OVH is using MAC Filtering than you cannot bridge eth0 unless you create the bridge using the same MAC address as the one eth0 has. Never tried so I just suppose it could work. You have at least three choices, you can either NAT a private class over eth0 and define that network in OpenNebula, you can acquire a /29 block, create a bridge, set the first public IP address on it and define the network in OpenNebula, or a combination of both. You can choose to use Linux bridge or OpenvSwitch. Either of the two are really easy to set up and running. OpenNebula has network drivers for both of them. I would choose OpenvSwitch :).

Re: [one-users] /var/lib/one/remotes/ or /var/tmp/one
Hello Thomas, The probes that leave under /var/lib/one/remotes are copied by OpenNebula on the compute node when you create the host. They are also synced whenever you want them to with `onehost sync`. By default OpenNebula stores the copy on the compute nodes in /var/tmp/one. This is documented in the Managing Hosts [1] documentation. I hope it help you.

Re: [one-users] greetings
Hello Galimba, I would like to kindly welcome you to the magic world of Cloud Computing :). I think your decision to use OpenNebula for your needs was a wise one. A road filled with fun, amusement and sometimes frustrations lay ahead. Enjoy. When I've first read your E-Mail I thought at exactly the same solution as the one pointed out by you, connect to the firewall and modify the iptables rules. I would choose to modify them via a hook [1] because I don't like to mangle with deploy. You might ask why is that? In case of update in the future you don't have to worry that your deploy script gets overwritten. Another safe option would be to copy the whole virtualization manager and name it kvm-local and modify the deploy script there and update the hosts to use that driver. Another solution that came to mind is to define a pseudo public network in ONE using a desired private range. Then map the last octet from you public range with the one in this private range. Easier to remember, though your users might not agree. I think it's easier if I write an example. Public: X.Y.Z.*100* Private: 172.16.0.*100* On the firewall you would have to DNAT each of those one 100 IP addresses to each of those private ones. You would have to do this once. For speed you can generate the rules with a basic for. Next step would be to hold [2] all the IPs from the private network (pseudo public) that you don't have available in the Public range. Not elegant, not user friendly but a (working) solution non the less. The most elegant solution I am aware of would be to create a VLAN subinterface for that /25 range on the firewall and configure a true public network inside ONE. It could even be done with bridging only without the hassle of setting up VLANs. But you need to be able to partition your network in this manner. It might not work for you. You're challenge is a really interesting one and I would like to hear other people opinions and possible solutions. It gave me food for thought and I am grateful for that.

The plan is to provide my research group with the IAAS that OpenNebula brings to the table. At the moment, I'm dealing with an issue I haven't been able to solve, and perhaps some of you could throw me a hint. My university assigned me over 100 public ip addresses to provide each VM. If I were to plug the cable directly to the OpenNebula box, then I know I could create my templates with public ip addresses and then everything should be fine. The problem is that I have a firewall in the middle, managing all the public ips, and my OpenNebula box is on a LAN behind that firewall. Is there an easy (and safe) way to assign public ips and pass tru the iptables on the firewall? I mean... the only solution I came up with was to modify the deploy script on the OpenNebula box to connect to the firewall and modify the iptables rules regarding the particular VM I'm trying to deploy.

With a simple hook you could enter the required DHCP host entry via OMAPI

Hello,
Is it possible that a virtual DHCP-server gives ip addresses to the
other VM's and that OpenNebula will take over this ip-address in sunstone?
Because now my dhcp gives the new VM an IP-address but in the sunstone
interface the VM has an other IP given by the Virtual Network template
can this be changed?

Re: [one-users] DHCP and OpenNebula
Hello Jaime,
I don't have a hook for that. It was an idea I came up with for this
particular use case. I don't use DHCP with OpenNebula.
Anyway, good question though. I have made a little bit of research about
OMAPI
and how can one use it from different programming languages.
Ruby:
https://github.com/pikelly/dhcpIT
http://www.ruby-doc.org/gems/docs/e/esxmagicwand-0.1.2/DHCP/Server.html
Python:
https://code.google.com/p/pyomapic/
https://github.com/jof/pypureomapi
Perl:
http://search.cpan.org/~jhthorsen/Net-ISC-DHCPd-0.14/lib/Net/ISC/DHCPd/OMAPI.pm
Bash:
http://www.jedi.be/blog/2010/12/08/automating-dhcp-management-with-omapi/(also
has a Java example)
http://comments.gmane.org/gmane.network.dhcp.isc.dhcp-server/11411
Hope it helps :).
Best,
Valentin

Do you have this hook per chance?

Re: [one-users] DHCP and OpenNebula
Hello Christophe,
The best place to start is the documentation about Using Hooks [1]. Keep in

that OpenNebula has the same level of quality in documentation like FreeBSD
does ;).
Whenever you have a problem check there first, 99% of the cases you will
find it there.

Re: [one-users] Contextualization
Hello Christophe, I suggest you follow Andrei's suggestion in the future. It is much cleaner and more OpenNebula way to say so. Read in line to continue with the process I have described.

The shared folder appears as a 9p [1] device inside the VM. You can find in [1] the way to mount it. One more thing though. The /tmp/contextualization directory and contents must be owned by oneadmin, because the VM runs under oneadmin user. This way you will be able to mount it in the VM. # chown -R /tmp/contextualization VNC to it, mount the shared folder in the host and install the deb/rpm. can you explain the boot parth of the whole process? and is this right what i did so far? Yes, it is perfectly right what you did so far. Again, Andrei's suggestion is way better and much simpler than mine. If you choose to follow the FILES approach please redefine your original one-45 machine. This way you won't loose your previous work, the already installed VM. # virsh destroy one-45 # virsh undefine one-45 # virsh define /var/lib/one/datastores/0/45/deployment.0 # virsh start one-45 Now your VM should be back under OpenNebula's control. You can stop it, add one-context to FILES datastore, modify the template to include the one-context file in the CONTEXT section. Boot the machine, mount the CONTEXT ISO (the CDROM) and there you'll have the one-context package.

On 11/21/2013 03:30 AM, Valentin Bud wrote: Hello Mark, Before pointing you to the problem I think your config has you should also check that you have routing enabled in the machine Are you speaking of ip route routes? Or some sysconf variable? Or, route(s) on the VMs themselves?? I was actually speaking about IP Forwarding, to be precise. That is attained via a sysctl. It should be set to 1. To make the changes persistent after reboot you have /etc/sysctl.conf. NOTE: Paths, configs might be different, I have once used OpenSuse, a billion years ago. # sysctl net.ipv4.ip_forward I have attempted ip route, to route to the VMs 10.0.0.0/24 network Where's 10.0.0.1 supposed be -- on the vbr0? Yes, 10.0.0.1 should be configured on the vbr0 interface and eth0 shouldn't be part of your Open vSwitch. and if you want Internet connectivity for VMs also NAT vbr0 over eth0. I want (1) internet connectivity to the VMs (VLANs) and connectivity out of the VMs network. Not sure how to get this going, though it appears the OVSwitch has all the MAC-addr info, for the VMs... Don't forget to NAT your 10/24 network over eth0 to have Internet connectivity available in the machines. Also you should have a DNS server running at 10.0.0.1 or change DNS from vnet to some recursive DNS server you have in your network. I suspect 192.168.1.1 is your DNS recursive server. If you want services from the VMs accessible from 192.168.1/24 network you can forward ports to specific VMs from your laptop (host) using iptables. Let's say you want to access a Web Server located on the VM with IP Address 10.0.0.100. You'd have to DNAT port 80 from eth0 IP Address to 10.0.0.100 port 80. And have your webserver available at http://eth0.ip.addr.ess. This might not be the case if your router has routes to 10/24 network through your laptop's eth0 interface. Currently, it does not. Just attempted, and can't ping to 10.0.0.3 VM. (output, below). If you want to access your VMs from the 192.168.1.0/24 you shouldn't NAT the 10/24 network over eth0 but configure your Netgear router with a route to 10/24 via your eth0's IP Address. I would recommend to enter a MAC address - IP binding in the router so your laptop receives the same IP Address on eth0 every time it connects to the network. Reading once again your config I see you've inserted eth0 in the vbr0 OvS bridge and that it has an IP address from the 192.168.1.0/24http://192.168.1.0/24 network. I suspect that is your local network. Yes, 192.168.1.0/24 is my external (laptop) network, including a Netgear router at 192.168.1.1. Do you have connectivity between your VMs using this setup? You should from what your setup tells me. The VMs, at 10.0.0.3 and 10.0.0.4 can ping each other, and ssh works between them just fine. They can only see the 10.0.0.0/24 network, and can't ping 10.0.0.1. They can't ping 10.0.0.1 because that IP Address hasn't been configured on any interface. Please follow the steps I have outlined in my previous E-Mail if you want NAT-ed setup. That should get you started in no time. Here they are: # ovs-vsctl del-port vbr0 eth0 # dhclient eth0 ( or set its IP address manually) # ovs-vsctl set Port vbr0 tag=0 # ip addr add 10.0.0.1/24 dev vbr0 # iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -d 0.0.0.0/0 -o eth0 -j MASQUERADE thank you, mark Hope it helps.

Also, you can check out the presentations [3] of the speakers if you want to consult a particular detail that you do not quite remember. And, to make the experience even more immersing, scout through the conference pictures [4]. All the above is great, and you will feel almost as if you were there if you didn’t. And we say almost because, as CentOS project director, Karanbir Singh, said [5], the real value of a conference is what happened behind the scenes, between talks, during the fantastic evening event. So, if you liked what you just saw, make sure you **save the date for 2-4 December, 2014!**.

Re: [one-users] OpenNebula and DHCP Server
Hello Fazli, I will make some assumptions about your infrastructure and provide possible approach(es). * Your KVM nodes have a single Ethernet interface, eth0, connected in a switch and a router used as the default gateway for the 192.168.1/24 network, * Also the frontend is connected via the same switch with the rest of the nodes, * You have a br0 bridge with eth0 connected to it on each node and also the frontend, * Your frontend is also a node. If you have access to the router the simplest way would be to add an IP Address alias on the router interface as the default gateway for the new network. Configure a new network inside OpenNebula for that using the chosen subnet and the same bridge, br0. I don't know if you have any kind of security policies in place but be careful that in this way there is no Layer 2 separation and traffic between the two subnets is visible with tcpdump or other sniffers. The second approach I can think about is to have the frontend configured with the first IP Address from the new subnet on br0 and define a new network inside OpenNebula like the above. I don't know if this would work though.The NAT must be done for 10.100.0/24 over 192.168.1.X (the IP Address of frontend from 192.168.1/24 subnet). What I don't know is if iptables can MASQUERADE subnets on the same interface. Never tried it, it might work. Another approach that come to mind is to use the Virtual Router and define a new subnet on the same br0 bridge. The Virtual Router would have an interface connected to 192.168.1/24 network and one in the 10.100.0/24 one. Setup it up to have the first IP Address from the 10.100.0/24 network so it is the default gateway. The same applies, traffic over L2 is not separated in anyway. One more idea :-) would be to use Open vSwitch and GRE tunnels between the nodes. In this way you can use VLANs and transport over GRE between nodes. You can also setup IPSec encrypted GRE tunnels if you want security. It might be overkill but again it depends on your requirements. Another working setup I have done is to use tinc VPN [1] between nodes in switch mode and connect it to the Open vSwitch from each host as a port. This way traffic that travels between nodes is fully encrypted and you can use the same L2 network in a secure fashion. But maybe the best approach would be to have a second network card, eth1, in each node. Connect that second card in an Open vSwitch and use VLANs with the frontend being the router, or any other node for that matter.

I don't really understand your concern. Could you be more specific? Yes, every VM will get a private IP address from the Router in case you connect it to the private network. If you connect the VM to the public network too you'd have to setup the IP address on the VM. If context package is installed in the VM it'll autoconfigure the public IP also.

My method is to use OpenNebula Virtual Router by refer to this page [1] and Openvswitch. I have installed Openvswitch in the host and I was able to deploy VM in isolated network. I try to deploy the VirtualRouter in a virtual network. In two virtual networks in fact, in the PUBNET which should be the 192.168 network from br0 on the nodes and frontend and PRIVNET in the Open vSwitch network. My problem is, I cannot ping it and cannot SSH into it. You should be able to connect to PUBNET's virtual IP Address from within the 192.168 network. Or you could add an internal port to Open vSwitch bridge and try to connect to PRIVNET's virtual IP Address of the VR.

You have to contextualize the machine before using it. That means you have to install the contextualization packages. Please do yourself a favor and read the contextualization overview [1]. Also read the fine docs on how to contextualize the VM for 3.8 [2]. plz help. Is it necessary to create template to contextualize vm created using NAT? Contextualization is simply some scripts that are run when the VM is booted. Those scripts come with the contextualization packages, which are available as DEB and RPMs so they work on RHEL and Debian based operating systems. The scripts activate swap, configure network interfaces based on interface MAC address and some other stuff. or contextulization is necessary for bridged mode? Contextualization is needed if you want your machine to autoconfigure the IP address and have the OpenNebula users' SSH public to be set as root's ~/.ssh/authorized_keys so you are able to SSH securely to it. I want communication between vms of different vlan. If you want communication between VLANs you can either use the Virtual Router [3] or you can provide routing using your host(s). It is up to you. Remember that routing is a function provided by a networking equipment, in this case the Virtual Router or the host.

Hello Fazli, The Virtual Router documentation [1] is definitely a good place to start.

I have download the image from Marketplace and Deploy a VM out of it. Then what should I do? My concern is that the Multiple VM will be able to be assigned a private IP address (at the same time connect to the internet) while the KVM host is using public IP address. I don't really understand your concern. Could you be more specific? Yes, every VM will get a private IP address from the Router in case you connect it to the private network. If you connect the VM to the public network too you'd have to setup the IP address on the VM. If context package is installed in the VM it'll autoconfigure the public IP also.

Re: [one-users] @vm contextulization
Hello anagha b, What version of OpenNebula are you running and what OS do you want to contextualize? If you are using CentOS, Debian or Ubuntu you just install the opennebula-context/one-context package, save the image and use it afterwards. You can read how to prepare the virtual machine image in the documentation [1]. It takes 10 minutes to get it up and running. If you are using other OS for your VMs you could provide the IP configuration from a DHCP Server or you could use the Virtual Router [2] for that.

Re: [one-users] virtio-blk-data-plane and x-data-plane=on
Hi Erico, This is the first time I hear about virtio-blk-data-plane. Thank you for the info, looks like this feature brings notable IO improvements. You can try to use the RAW Section [1] to pass special attributes to the underlying hypervisor. I have found a blog post [2] in which there is a method to enable virtio-blk-data-plane using the libvirt XML. The RAW section DATA gets passed to libvirt in XML format. I think the following could work: RAW = [ TYPE=kvm, DATA=qemu:commandlineqemu:arg value='-set'/qemu:arg value='device.virtio-disk0.scsi=off'//qemu:commandline!-- config-wce=off is not needed in RHEL 6.4 --qemu:commandlineqemu:arg value='-set'/qemu:arg value='device.virtio-disk0.config-wce=off'//qemu:commandlineqemu:commandlineqemu:arg value='-set'/qemu:arg value='device.virtio-disk0.x-data-plane=on'/qemu:commandline ] I don't have a test machine around and I would to hear back from you if it works or not.

Re: [one-users] iptables commands to run for externally access the applications run in the VM in a virtual LAN which is set up in a dedicated root server
Hi Qiubo, For directing traffic for a specific application (port) to a virtual machine I use the following: root at host # cat /etc/network/iptables *nat :PREROUTING ACCEPT :POSTROUTING ACCEPT :OUTPUT ACCEPT # Direct HTTP(S) traffic to 192.168.120.100 -A PREROUTING -s 0.0.0.0/0 -d 172.20.85.28/32 -p tcp --dport 80 -j DNAT --to-destination 192.168.120.100 -A PREROUTING -s 0.0.0.0/0 -d 172.20.85.28/32 -p tcp --dport 443 -j DNAT --to-destination 192.168.120.100 COMMIT *filter :INPUT DROP :FORWARD DROP :OUTPUT ACCEPT :PUBLIC - # INPUT CHAIN -A INPUT -i lo -j ACCEPT -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -i eth0 -j PUBLIC # FORWARD CHAIN -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -i lo -j ACCEPT -A FORWARD -i eth0 -j PUBLIC # OUTPUT CHAIN -A OUTPUT -d 224.0.0.0/4 -o eth0 -j DROP # PUBLIC CHAIN -A PUBLIC -s 0.0.0.0/0 -d 192.168.120.100/32 -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT -A PUBLIC -s 0.0.0.0/0 -d 192.168.120.100/32 -p tcp -m state --state NEW -m tcp --dport 443 -j ACCEPT COMMIT The above permits all RELATED/ESTABLISHED traffic to pass through the firewall on both INPUT and FORWARD chains. It also permits traffic to pass freely on the lo (loopback) interface. All traffic coming in on eth0 is directed to the PUBLIC CHAIN. On the PUBLIC CHAIN I allow traffic to destination ports 80 and 443 to the inside (LAN) IP address. To start the iptables on boot I have the following in `/etc/network/interfaces`: # Loopback device: auto lo iface lo inet loopback ### Start and configure iptables and ip6tables at startup up iptables-restore /etc/network/iptables up ip6tables-restore /etc/network/ip6tables WARNING: The above is only an example and should not be blindly copied and expected to work.

That NAME could be used in the template also. Maybe NAME is not the proper way for this variable. I meant that maybe NAME is not the proper name for this variable. Another question would be: could I use a variable, DB_NAME for example, in the template and reference that from within IMAGE? I will try this today and come back with the results. DB_NAME=dbtest HOSTNAME=$DB_NAME DISK=[ IMAGE=vdb.$DB_NAME.domain.tld ] I am trying to simplify the instantiation process for the users by providing the template and creating the second disk on the fly. In this way the user would only change the DB_NAME to a given name and everything would happen automagically behind the scenes. For now, the user needs to clone a persistent image for the second disk, change the $HOSTNAME and the name of the second disk to the one previously cloned. After this two steps the user can instantiate the new VM. This process is prone to human errors. If I could save the second disk and reference the DB_NAME from within IMAGE I would restrict all the attributes from the template besides DB_NAME and the process would be less prone to errors. Does the above make any sense? The above applies to my use case. In my case each project I run on top of OpenNebula is a (sub)domain. The above would ease the process of instantiating a new VM. Maybe I could even use a hook to create the second image on the fly at CREATE time, though I think OpenNebula would complain that the disk is missing. Haven't tested this yet. I am off the track here. It would be nice to be able to save the Volatile disks. In my use case we need to preserve the disk on which the DB lives for accounting purposes. I don't see a point in reinventing the wheel with a hook. Thanks for your input on this matter. Cheers and Goodwill, Thoughts? Thanks.

OpenNebula 4.0 includes new features in most of its subsystems. We are showing for the first time a completely redesigned Sunstone, with a fresh and modern look and an updated workflow for most of the dialogs. The also new Sunstone Views functionality allows to customize the GUI for each type of user or group, so the interface implements a different provisioning model for each role. A whole new set of operations for VMs like system and disk snapshoting, capacity re-sizing, programmable VM actions and IPv6 among others. There are some new drivers also, like Ceph; as well as improvements for VMware, KVM and Xen. The scheduler has received some attention from the OpenNebula team to easily define more placement policies...and much more. As usual OpenNebula releases are named after a Nebula. The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745-46. It is located about 7,000 light-years away from Earth. And last, but not least, we want to give a huge THANKS to our community, without whom OpenNebula wouldn't be anywhere as near as good as it is today. So, let's fly over the clouds riding the Eagle ;) LINKS * Complete Release Notes: http://www.opennebula.org/software:rnotes:rn-rel4.0 * Download: http://downloads.opennebula.org/ * Documentation: http://opennebula.org/documentation:rel4.0 * Screencasts: http://opennebula.org/documentation:screencasts -- Join us at OpenNebulaConf2013 in Berlin, 24-26 September, 2013 -- Constantino Vázquez Blanco, PhD, MSc Project Engineer | OpenNebula - The Open-Source Solution for Data Center Virtualization Join us at OpenNebulaConf2013 in Berlin from the 24th to the 26th of September 2013! www.OpenNebula.org | @tinova79 | @OpenNebula ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org ___ Users mailing listUsers@lists.opennebula.orghttp://lists.opennebula.org/listinfo.cgi/users-opennebula.org ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org -- w: http://databus.ro/blog in: http://www.linkedin.com/pub/valentin-bud/9/881/830 t: https://twitter.com/valentinbud ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

One more thing, why does OpenNebula need the Linux bridge compatibility layer enabled? This is basically a requirement from the hypervisor that uses brctl addif... KVM (through libvirt) supports Openvswitch without compatibility layer since version 0.9.11. We opted to preserve this requirement and remove it in future versions (and add virtualport for NICs). Note that the driver itself does not require the compatibility layer, as it uses openvswitch commands. If I understand correctly I can disable bridge compatibility. Do you think it would be wise to stay current with latest libvirt Official Releases? Thanks for helping.

No `server_core` Authentication driver. I have changed
`/etc/one/oned.conf` to include it in `AUTH_MAD`.
Again as `oneadmin` issue `sunstone-server start`. Now the `oned.log`
shows something different:
`/var/log/one/oned.log`

Found out what was wrong. User `serveradmin` had `server_core` setup as
`AUTH_DRIVER`. Changed it to `server_cipher` and it works now, Sinatra
has taken the stage.

Re: [one-users] OpenNebula 3.8.1 ovswitch ovs-ofctl bad syntax for in_port
Hello World, Sorry for the excess emails. My email client went crazy. I will pay much more attention in the future. Back to OpenNebula and OpenvSwitch drivers Mr. Ben Pfaff put it nicely It is important to understand that a fake bridge is neither an OpenvSwitch bridge nor an OpenFlow switch. Thus, you cannot use them in most contexts where an Open vSwitch bridge or an OpenFlow switch is required. I am surprised that the word fake in the name does not make this clear. Using the bridge the fake bridge is part of, it works: ``` $ sudo /usr/bin/ovs-ofctl dump-ports br0 vnet0 OFPST_PORT reply (xid=0x1): 1 ports port 17: rx pkts=680611, bytes=204556006, drop=0, errs=0, frame=0, over=0, crc=0 tx pkts=675160, bytes=352172599, drop=0, errs=0, coll=0 I am going to keep current with libvirt and drop the bridge compatibility layer out of the ecuation. That's the reason I have fake bridges to begin with. Thanks.

Re: [one-users] VMs IP Clash after failure
Hi Carlos, On Tue, Nov 13, 2012 at 11:17:29AM +0100, Carlos Martín Sánchez wrote: Hi Valentin, That's exactly how it works now. When you set NIC = [ NETWORK_ID = vnet_id, IP = ip ] You are not hardcoding the IP, you are requesting that IP from the leases of the network. It will be assigned only if it is free, and will be marked as used, just like any other IP assigned automatically. You are right. I have done some test now and it works as you say it does. I meant something else though. I will take it step be step so I can make myself understood. I have one template with ID 17. ``` $ onetemplate show 17 | grep IP IP=172.16.18.54 ``` I clone the template and try to instantiate it and an error pops up telling me that the IP address is taken, which is the right thing to do. Now, as an user when I create a new template, either by `create` or `clone` I have to *remember* to modify the IP address in case it is in use. I have to find out which is the next usable IP addresses by looking at all templates. I can see the active leases using `onevnet show` by I don't have a way to know if the IP I choose to use in the new template is in use by other templates or VMs. That's not a problem, more of a user friendly thing.

As far as I have noticed whenever you instantiate a machine OpenNebula uses the next IP address from the defined pool in the vnet. That's almost DHCP. One can check the status of the network using `onevnet show vnet_id`. Under `USED LEASES` one can see what leases are in use. If, for whatever reason, one wants a certain ip address to use for a particular VM, one can use `IP=x.x.x.x` in the template. I think here arises an issue. Human beings aren't good with numbers, that's one of the reasons we have DNS. I for one, forget which IP is allocated to which VM, I am talking about the ones I specify in the template using `IP`. I don't care which IP is allocated to which VM, I just care which IPs are allocated or, better said, reserved from the pool. I know there tools that perform the specific function of IP address management. OpenNebula could check if the IP address is in use whenever one creates/clones a template. The reserved IP address could be listed with `onevnet show vnet_id` under `RESERVED LEASES` or something. What do you people think about this? I also am aware that you guys welcome patches. I wish my Ruby skills were better so I could code this feature by myself. Speaking of Ruby, does anyone have some good docs for a noob? :) Cyrille, I hope I haven't hijacked your thread. I think the above thoughts are connected with your last question from your email. If that's not the case I am sorry.

[one-users] OpenNebula 3.8.1 ovswitch ovs-ofctl bad syntax for in_port
Hello World, I have updated OpenNebula to 3.8.1 from source on CentOS 6.3. I have noticed that ovswitch vnm now adds flows. That's very nice. I have never worked with flows from OpenvSwitch but I have read a little bit about it and they seem to bring a lot of (security) benefits. However the `post` ovswitch vnm script fails. ``` /var/log/one/oned.log Mon Nov 12 15:17:44 2012 [VMM][D]: Message received: LOG I 216 post: Executed sudo /usr/bin/ovs-vsctl set Port vnet0 tag=5.

The OpenFlow default rules employed by OpenNebula state on the doc [2] page the following: `These rules prevent any traffic to come out of the port the MAC address has changed.` Does this mean that traffic coming out of the port OpenNebula just created on the switch is denied/dropped? Or does it mean that traffic with the source MAC address of the VM should only come in on the specified port, the newly added port for the VM? Maybe I'm wrong, but at a glance flows can improve security and thus are a huge improvement to OpenNebula. Do you, devs and users, think that it would be better to separate the flow definition from code? For now if we want to add flow rules we have to modify `/var/lib/one/remotes/vnm/ovswitch/OpenvSwitch.rb`. I think it would be wise to have separate files with rules based on the users' need. `ovs-ofctl` can add flows directly from a file so it wouldn't be very hard, I guess, to separate the flows from the code. Of course one can do this by himself by modifying `post`. One more thing, why does OpenNebula need the Linux bridge compatibility layer enabled? Can anybody shed some light?

Re: [one-users] The type of processor required for OpenNebula setup
Hello there, OpenNebula *doens't* require a certain CPU. The OpenNebula frontend doesn't even require x86_64 architecture. It can be installed on i386 also. The virtualization hypervisor in use require a certain CPU, or more specifically, a certain extension, the virtualization one. Since you are asking about CentOS 6 I think you'll use either KVM or Xen. As far as I know they both work with either Intel or AMD CPUs with virtualization extensions. Maybe AMD names this different, I don't know.

Re: [one-users] Failed to create VM domain
Hi, I have managed to get OpenNebula running on a CentOS 6.3 host. First thing that comes in mind is polkit. I honestly don't remember the exact error I have received but I do know that OpenNebula didn't work until I have configure polkit. # cat /etc/polkit-1/localauthority/50-local.d/50-org.libvirt.unix.manage-opennebula.pkla [Allow oneadmin user to manage virtual machines] Identity=unix-user:oneadmin Action=org.libvirt.unix.manage #Action=org.libvirt.unix.monitor ResultAny=yes ResultInactive=yes ResultActive=yes Also qemu is configured to run under oneadmin user and group # cat /etc/libvirt/qemu.conf | egrep ^user|^group user = oneadmin group = oneadmin Another problem I have encountered using libvirt installed from rpm is that the VMs won't start complaining that some lsi device is missing if you use IDE or SCSI disks. This is easy, just go with virtio devices. I think the simplest way to setup this would be to edit /etc/one/oned.conf and change DEFAULT_DEVICE_PREFIX. DEFAULT_DEVICE_PREFIX = vd Other than that I've had no problems. Well one more, but that's specific to my environment. I user OpenNebula with RVM for Ruby and the init.d script couldn't find the ruby executable. For everyone who's interested in this I have added the RVM ruby path to $PATH in oned init.d script: # Source function library. . /etc/rc.d/init.d/functions RETVAL=0 PATH=$PATH:/usr/local/rvm/rubies/ruby-1.8.7-p370/bin/ Oh, one more thing, I have installed OpenNebula 3.6 from source.

Re: [one-users] open /dev/kvm: Permission denied on Debian Squeeze
Hello Javier, Thank you for your answer. Indeed, changing /dev/kvm group to oneadmin solved the problem. I can now happily launch VMs on the Cloud. For future references, to make the change persist after reboot I have done: # cat /etc/udev/rules.d/60-qemu-kvm.rules KERNEL==kvm, GROUP=oneadmin, MODE=0660 I have also read the man page for udev to get this right. Learned something new today :). Maybe the OpenNebula developers could add this to the documentation in the KVM Configuration [1] section as a note for Debian Squeeze. NOTE: On Debian Squeeze when creating a VM as a regular user, the only group that is taken into account is the one that appears as 'gid' (oneadmin in this case). To solve the problem change the owner of /dev/kvm 'to root.oneadmin.

[one-users] OpenNebula CloudWorkshop Romania Timișoara
Hello Community, My name is Valentin Bud. I have started using OpenNebula a few months ago. I thank you for this great you are developing. Words cannot really express gratitude. I have been playing with OpenNebula until now, no production deployments but those are about to follow really soon. I like the tool because it gives you flexibility. What I love about it is that I can do a lot of things using shell scripts. In 16.02 February I am going to host a CloudWorkshop for the local business and student communities. In the first part of the Workshop I am going to talk about the Cloud from a business perspective and how could the Cloud help small companies or startups. The second part is dedicated to the students from the local technical university Universitatea Politehnica Timișoara. I am about to build an email Cloud using OpenNebula for my personal use, and present OpenNebula and the email Cloud as a case study. This workshop is the first from a series that I want to make around Romania in cities were are the most recognized technical universities, cities like Cluj, Iași, București. Cloud Computing is the future and I want to promote this concept throughout Romania so we don't remain behind on this. In cities were are technical universities is a concentration of creative and innovative minds among the students. Why am I telling you all this? As an appreciation for the work this community has put into OpenNebula. If I am going to use OpenNebula you should know about it. It is you, the community, who made this possible. I don't want to make marketing on this mailing lists, and if I am crossing the line with this please remove the message, but the event has a facebook page at the following link - https://www.facebook.com/pages/CloudWorkshop/137624213023654. The page is in Romanian though.

Re: [one-users] Mixed mode UBUNTU+ RH KVM
Hello Nikolay, On Wed, Dec 14, 2011 at 4:06 PM, Nikolay Gar nikolay@gmail.com wrote: Hello folks ., Quick question .. If it possible to use as FrontEnd based on Ubuntu 11.04 and 2 Cluster Nodes on RH ES 6.0 as KVM nodes? Thank a lot Nikolay SSH is used to communicate with the nodes in order to either transfer the VM image, if SSH Transfer Manager is being used of course, or to gather status information about the load/health of the node. If you are using NFS as storage backend the nodes must have a compatible NFS client in order to mount the shares. libvirt is setup on the nodes in order to start/stop/deploy VMs on top of KVM. SSH, NFS are protocols and libvirt is a standard library, so your mix should work. I'm not trying to be condescending or something, just that I'm approaching your question using the mentioned logic. The docs don't specifically talk about mixing distributions.

I could be wrong so others who know better please step in and clarify.

I think it's the best way to run OpenNebula. You can run OpenNebula and VMWare Workstation Server hypervisor on the same machine, but not on ESX(i) hypervisor host because that's a bare metal hypervisor.
