Re: [one-users] OpenNebuka Hosted-VLAN support
Hello Patrice, you make very valid points and we're aware of those limitations. They have actually been reflected on the documentation: http://opennebula.org/documentation:rel3.0:nm#considerations_limitations The problem is that the network management is based on the hook subsystem, but we have realized there should be a specific driver for networking. We have created a feature ticket to develop this functionality: http://dev.opennebula.org/issues/863 The target release for this functionality is OpenNebula 3.2. For the moment, in OpenNebula 3.0, the only solution to the aforementioned problems is to create a static network configuration.

Hello Prakhar,
are you still experiencing this issue? It looks like a system setup problem.
Do you have any further information on this problem?

Re: [one-users] Hi, I have some questions about Open vSwitch management in Opennebula 3(feature 476).
Hello, When we released OpenNebula 3.0, we finalized the network configuration documentation, you can see how to activate the Open vSwitch integration here: http://opennebula.org/documentation:rel3.0:openvswitch When you originally wrote this email this guide wasn't yet written (the network drivers themselves were still under development). I hope it answers your questions. It addresse the 'brctl' by indicating that the Open vSwitch compatibility layer for Linux bridging must be installed: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=INSTALL.bridge;hb=HEAD Cheers, Jaime On Tue, Jul 26, 2011 at 2:58 AM, wen.y...@cs2c.com.cn wrote: Hello developers: I am interesting about feature 476 that Open vSwitch management in Opennebula 3.

If I want to use these scripts to test the Open vSwitch management function, what should I do? (2) In vnm_mad scripts, 'brctl' command is used to control bridge. The 'brctl' command can't work normally if the bridge module is not loaded. But it is neccessary to start Open vSwitch that remove the bridge module(rmmod bridge).

The bridge created by 'brctl' command can't be used by Open vSwitch because the bridge information isn't stored in ovsdb. So, I think that the 'brctl' command can't be used in vnm_mad scripts.

Proxmox is quite well established but at this point Opennode seems more promising, that's the reason why i invite you to have a look on its features, its roadmap and its features requests ( http://opennode.activesys.org/forum/index.php?board=5.0). Taking as a basis you already know both of them quite well and as you're still asking details for a bare-metal approach, then i suppose you ask for a more advanced view of bare-metal in comparison to the status where most of them are now. Some interesting points : - Hot deployment of templated bare-metal : based on pre-established bare-metal configurations (or templates if your prefer), setup to deployment automation of as much as wanted bare-metal ready to boot from the network. These configurations concern the bare-metal themselves but also the configured image appliances they are supposed to host for a given goal. - Central management of these deployed bare-metal and the mentioned configurations with Sunstone. All Sunstone capabilities being possible through API too. - Appstore like : taking advantage of third party software for deploying new functionnalities either on the platform (the bare-metal itself) or through image appliances. The load balancing Opennode feature request ( http://opennode.activesys.org/forum/index.php/topic,95.0.html) is an example of image appliance serving the capabilities the bare-metal has to offer.

Re: [one-users] Tiny Local Business scenario for openNebula
Hi, OpenNebula can be used for the scenario you describe, even if you are not going to take advantage of its on-demand cloud features. It will provide a centralized view and management of your Images and VMs, what will surely help to administer and monitor your virtualized workstations. OpenNebula can use the same computer as the front-end and host, the only thing to keep in mind is that you need to use the shared storage transfer manager [1] (the front-end and the hosts are sharing the same storage). Knowing that all the VMs will be windows, you may want to configure remote desktop access to the guest OS instead of VNC. Regards.

Kind regards, Diego 2011/10/26 Ben Tullis b...@tiger-computing.co.uk: Hi Diego, I don't think that OpenNebula is likely to be the best tool for the job in this case, as it is more geared towards on-demand cloud computing. However, it does sound like you could really benefit from virtualization in the office. The way I would approach your situation is as follows. Make sure that the machine you're going to use as a server has hardware virtualization support built in. http://en.wikipedia.org/wiki/Intel_VT#Processor Use disks in pairs of equal sizes, then install Linux and configure software RAID1 so that the system will be able to withstand a failure in any disk. http://en.wikipedia.org/wiki/Mdadm Install a hypervisor to enable you to run many concurrent virtual machines. You might like to consider KVM, Xen and Virtualbox. http://www.linux-kvm.org http://wiki.xensource.com/xenwiki/ http://virtualbox.org You can then define virtual machines and install Windows onto them, in order to make them available to your colleagues. You can use normal Windows system management techniques (such as sysprep) to deploy pre-configured Windows system images, thereby saving you time. You could then use VNC to make these virtual machines available to your staff, in the manner that you suggest. I'm currently looking at building an OpenNebula cluster to support a small-business requirement, but I can't really see that there is any way of ensuring high-availability in any system with fewer than four physical servers in it. I think you'd be making things unnecessarily hard for yourself if you tried to do it all on one server. I hope that helps.

[one-users] Looking at moving to OpenNebula with a few questions
Hello all, I have been running Xen on our virtual servers here for a while now. Recently we have added some machines and it has come up that we need to redo our virtual servers to better utilize them. The main thing the higher-ups are requesting is a GUI to manage the environment. So I asked on the xen-users list and they pointed me to OpenNebula. So far I like what I see. Support for Xen, KVM, and VMWare is a plus for future expansion if needed. I have a few questions though. Below is our current machine and SAN specs. I want to fully utilize all of them and have some level of failover, either manual or automatic, for when I need to bring a machine down for maintenance. Here's the specs: xen-test: Testbed machine:Dell 2900; 8x 300GB in raid6, 8GB ram, 1x Intel 5405 quad core 2.0Ghz, 2x gigabit nics xen1: Production unit: Dell T710; 8x 2TB in raid6, 24GB ram, 2x Intel 5504 quad core 2.0Ghz, 4x gigabit nics xen2: Production unit: Dell R610; 3x 160GB in raid5, 32GB ram, 2x Intel 5506 quad core 2.13Ghz, 4x gigabit nics SAN: Dell MD3200i; 12x 2TB in raid6, dual controllers. Currently all machines have their network cards bonded and vlans passed over the trunked interface as we have approximately 20 vlans we use. This should be fairly simple to do with OpenNebula correct? I have a mix of local and network storage. Should OpenNebula be able to handle both local and SAN storage? All raid is hardware based. With the current setup what is the best way to set it up for best fault tolerance/speed/space? What is the best OS to start with? We currently use Centos 5.5 on all 3 nodes but would prefer Fedora or similar. Debian would be doable also. Would I be able to import the existing virtual machines that are running into OpenNebula? I know that one major performance hit is the raid6 and it would be better to do a raid10. At the time xen1 and the SAN were purchased they were all we had so fault tolerance with maximum space was top priority over speed. We may look at redoing this soon. We are a small state government agency with little to no IT budget so I have to work with what I have. Please keep that in mind before suggesting why not buy such and such Thanks in advance for the input. -- Donny B. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

[one-users] Using Requirements and Rank to create only one guest of type X per host
Howdy! We’re currently implementing OpenNebula as a test to see if it fits our infrastructure needs. We have a specific requirement for some guests to have direct access to a raid0 array on a host. We obviously only want one of these guests to be running on each host. (Yes, raid0. The work they’re doing needs fast disk access with bulletproof locking, but the results get shipped elsewhere when it’s done. It’s an ideal fit for a cloud since the ) I can’t tell from the requirements/rank manual page how to set a requirement that this disk space is not currently used by another VM. Worse, some of our dom0/hosts have two of these resources, of a slightly different type, to allocate. Note that the machines will all be named a particular way, so I could put in an exclusion that only select a host named like “dd” where a “gdd” machine is not running, for example, but I’m not sure how to do the second part of that. We also want those hosts to start first when a host or the cluster comes back up. If I’m reading the documentation correctly, that means that we would use the rank algorithm somehow — but by my read of the documentation, that was only for host selection, not boot priority. Manually coupling a particular VM to a host would also work, but I can’t figure out how to do that yet within the scope of the “VM Template” scheme either. Does anyone have any suggestions on how to implement this resource constraint in “the OpenNebula way”? Last but not least, I’d like to have a the SSH transition, the LVM transition manager, and the Shared transition manager all enabled. Do I simply uncomment all three in /etc/one/oned.conf, or do I need to use some other syntax? The manual is not clear on this.

This feature seems to work correctly when a new instance is deployed, as it is stated in oned.conf, hm-vlan hook is executed in PROLOG state. However, there are another states where VLANs and bridges should be created (or its existence checked) before executing a concrete operation: * Migration/Live migration of an instance to a hypervisor where VLAN and bridge of the instance has never been created VLAN and bridge existence should be checked and created if necessary before migration is executed. Opennebula 3.0 RC1 performs migration without doing these checks and fails to migrate/live migrate the instance, leaving it in a FAILED state. * A failed instance cannot be redeployed to a hypervisor where VLAN and bridge of the instance has never been created VLAN and bridge existence should be checked and created if necessary to redeploy the image to the selected hypervisor. * A stopped instance cannot be resumed if VLAN and bridge of the instance does not exist. If we stop all instances of a concrete hypervisor and reboot the hypervisor for maintenance purposes, all bridges and VLANs will be deleted. Stopped instances won't resume because VLANs and bridges requirements are not satisfied and will enter in a FAILED state (performing a deletion of non persistent disks; BTW, we have removed deletion lines in tm_delete script for the moment, :D). So, VLAN and bridge existence should be checked and created if necessary to resume/migrate/livemigrate/recover_from_failed_state the instance to the selected hypervisor. As it is stated in oned.conf, hm-vlan hook could be executed on: # Virtual Machine Hooks (VM_HOOK) defined by: # name : for the hook, useful to track the hook (OPTIONAL) # on: when the hook should be executed, # - CREATE, when the VM is created (onevm create) # - PROLOG, when the VM is in the prolog state # - RUNNING, after the VM is successfully booted # - SHUTDOWN, after the VM is shutdown # - STOP, after the VM is stopped (including VM image transfers) # - DONE, after the VM is deleted or shutdown # - FAILED, when the VM enters the failed state But I'm not able to find a procedure to implement these functionalities in oned.conf for the states I mentioned.

Re: [one-users] Using Requirements and Rank to create only one guest of type X per host
Thanks! That helps with the VM pinning aspect greatly. I didn't realize that the custom variables could be used in constraints. My other questions concerned a cold start of the cluster and the cluster drivers. There is very little information about what happens during a cold start. In our case, some dependencies need to start before other cloud/cluster services can fully start. Is there a way to script this startup process so that we can be sure that these depended-upon VMs are started first? Second, what is the proper configuration in /etc/one/oned.conf to be using the TM_LVM transfer manager driver simultaneously with the TM_SHARED transfer manager? The manual and configuration files aren't clear on this point ... They emphasize that multiple transfer managers can be in use unlike multiple image manager drivers, but don't give an example of that configuration. Thanks, Karl Katzke Sent from my shoePhone.
