Re: [one-users] Can't access to VM through ssh
Hi again, Let's check the basics, just in case: a) The ttylinux machine you are using is the one downloaded from our site, so it is correctly contextualized. b) And you are trying to access the VM 192.168.0.6 from a machine in the same 192.168.0.X network, right? You may want to try adding another NIC attribute to the template, attached to your public network. This way you could access the VM from anywhere, not just the private network.

Re: [one-users] Sparse Images with 2.0
Hi Frank, You could modify the core to make it keep the SIZE sub-attribute in the DISK attributes, but that seems rather complex for what you need. It looks to me that the best approach would be #2, considering you have already your custom transfer scripts. You could just add a new attribute, something like DISK = [ IMAGE = imageA ] DISK_SIZE = [ DISK_ID = 0, SIZE = 1024 ] DISK = [ IMAGE = imageB ] DISK_SIZE = [ DISK_ID = 1, SIZE = 2048 ] Or a more readable option DISK = [ IMAGE = imageA ] DISK_SIZE = [ IMAGE = imageA, SIZE = 1024 ] DISK = [ IMAGE = imageB ] DISK_SIZE = [ IMAGE = imageB, SIZE = 2048 ] Regards, Carlos.

This has been working great and I've been happy with it. My question is with the changes in the 2.0 branch and with the new images repo, what would be the best way to accomplish this task? I'm all on board with the new 2.0 image structure, but I'm trying to figure out how to proceed. Thoughts I have so far: 1. Modify the code to allow the SIZE option to be retained even though image is specified; right now any extra template parmeters are removed before saving to DB 2. Create a special new parameter for sparse imaging growth, and modify tm custom scripts to accommodate 3. Throw out the whole tm custom scripts methodology and use hooks, but still need method to store SIZE of final image in DB. 4. Use context, but modify it to work before image is booted.

Re: [one-users] OpenNebula 2 RC: Why do image names have to be unique?
Hi Carsten, Yes, it is necessary if you want to be able to use the image name's in the template, like DISK = [ IMAGE = Ubuntu Lucic ] Otherwise, you are forcing the users to use images by their IMAGE_ID, which is an internal ID that can change at any time, e.g., you define templates for your IMAGE Ubuntu and a VM that uses Ubuntu, but the VM template has be modified if you delete and register again some time later that IMAGE) Regards, Carlos Martín, Cloud Technology Engineer/Researcher DSA Research Group: web http://dsa-research.org and blog http://blog.dsa-research.org OpenNebula Open Source Toolkit for Cloud Computing: http://www.OpenNebula.org On 29 September 2010 07:20, carsten.friedr...@csiro.au wrote: Trying to insert a second image with the same name into the image repository creates an error on the database layer.

Re: [one-users] putting OS images in the image repository
Hi Steven, This is an interesting use-case. When we designed the image repository, we had to make a compromise between expectable behaviour and advanced customization usage. I guess this falls into the advanced usage, but OpenNebula is flexible enough to take this challenge. To automatically save all VM disks that use a certain Image, you can use hooks. I would add a new flag to all the relevant images in your system, either having them in the image template, or adding them afterwards [1]: oneimage addattr image_id AUTO_SAVE YES This will add the flag to the template: $ oneimage show 1 IMAGE INFORMATION [...] IMAGE TEMPLATE *AUTO_SAVE=YES* DEV_PREFIX=hd NAME=test_image PATH=/home/cmartin/trabajo/scratch/steven/disk.img TYPE=OS To add a new hook to the system, edit $ONE_LOCATION/etc/oned.conf [2] and add something similar to the following: VM_HOOK = [ name = auto_save, on= CREATE, command = auto_save.rb, arguments = $VMID ] This will execute a new script, placed in $ONE_LOCATION/share/hooks/auto_save.rb, every time a new VM is created. I suggest you to use ruby, because the ruby OCA API [3] will make it easier. This script will have to: 1) Get the complete information for VM vm_id from OpenNebula. 2) For each disk, check if it is using an Image. 2.1) Get that image's information, and look for the AUTO_SAVE=YES attribute. If it's present, then issue a onevm saveas operation over that vm-id and disk-id. To be able to identify the disks later, you could include in the new image name the vm-id_disk-id string. This way, files will be all managed by OpenNebula in the repository. If you are doing this for back-up purposes, and you won't actually instantiate a VM using this saved images, you can always move that files away from the repository and then delete the images. This is the easiest and elegant way I see to do this, but any other opinions are welcome. I'd also like to ask the community if more people feel this should be supported out of the box by OpenNebula. If so, we could start a discussion to determine the specific features or requirements this would imply. Best regards, Carlos.

Re: [one-users] Some basic questions after a firts OpenNebula 2.0 install
On 3 December 2010 17:54, jean-paul.piga...@bull.net wrote: Hi OpenNebula. Hi Jean-Paul, This is my first mail on this list. So it contains some basic questions we have after making a first install of OpenNebula 2.0. First of all: the context: We have installed OpenNebula 2.0, compiled from downloaded source files. All the mandatory librairies are there but we have got some errors because OpenNebula requires a precise librairy version (ex: libcrypto.so.6 when we have libcrypto.so.10 in Fedora14). Anyway, we have succeeded to install a front end and a clusternode, both on Fedora12. We had to do everything using command lines. The configuration of the Vms and the network must be done manually in text files. Is this the normal way ? Yes, OpenNebula uses simple, human-readable templates to make it both user and script friendly as possible. To get a graphical interface, do you suggest us to try *Management Console* from Sara ? You may want to ask about it in the ecosystem mailing list [1], but as far as I know the Management Console [2] is only compatible with OpenNebula 1.4. The EC2 Query API tools [3] are a user-oriented alternative, you can give it a try and check if it suits you needs. The creation of images (of OS) must be done through an external tool (like virt-manager). Is this correct ? The actual virtualization will be performed by the hypervisor of your choice, so you can use any available tool for it. But it is not mandatory, you can create them using only OpenNebula (creating blank images, where you will install the OS form a cd-rom iso). OpenNebula manages the Vms but not the OS images. Is this correct ? This was true for 1.4, but in OpenNebula 2.0 the Image repository [4] was introduced; and now you can let OpenNebula manage your image files. To manage IP addresses in the VMs, we need to use the contextualization mecanism. Is this correct ? That's the preferred way, yes. As a reminder, the contextualization guide is documented in [5]. There was an interesting thread some weeks ago about using DHCP instead, you can check it in the list archives [6]. If we want to interface with a Vmware cloud, we need to use the Wmware drivers from C12G labs. That's right. Links: usage guide [7] and addon download [8].

Re: [one-users] OpenNebula 2.0.1 sets incorrect ARCH.
Hi John, The ARCH can't be defined in the Image templates. We are considering a new feature that will let you register VM templates in a VM catalog, to be instantiated easily just using its name or ID. This way you will be able to register at the same time the OS image and the VM template that uses that image. Would this fit your requirements?

Re: [one-users] Writing one template that allows for persistent VM:
Hi Steven, On 4 February 2011 05:22, Steven Timm t...@fnal.gov wrote: hOn Thu, 3 Feb 2011, Steven Timm wrote: I am trying to come up with a prescription for users that allows the following sequence: 1) Launch a VM based on a standard VM repository template 2) Save the contents of the VM back to the VM repositor\ 3) Relaunch the VM without modifying the template. I've tried the following thus far: 1) Launch the VM initially from a VM OS file outside the VM repository with save=yes. this does save the VM OS but just to /var/lib/one/vmid/disk.0, not back to the original file. User must copy that file somewhere and/or change their template. 1a) Launch the VM and then execute a onevm saveas command. this gets a copy of the image back to the image repository but again user must modify the template to relaunch the VM. 2) Make a public VM image in the repository, launch from that. Problems--even if image is public, other users (even oneadmin) can't read it and sometimes I myself can't read it, without going into the image repo and chmod'ing the file by hand. And again you are forced to save back to something other than the original file. 3) Make a persistent non-public image in the repository. Again there are permission problems launching, and it can only be used once by one user. Even so I can't get it to save back to the repository. If the user makes and saves the persistent non-public image in the repository, it is then necessary to go in and change the permissions on the file in the repository, otherwise the oneadmin user can't read it. But once this is done, it is possible to start the VM from the repository and save it back to the same place in the repository when it is done. When OpenNebula is installed, the images directory is set up with the sticky bit. From install.sh: chmod 3770 $DESTDIR$IMAGES_LOCATION In [1], it says The IMAGE_REPOSITORY_PATH can be changed to another administrator defined folder. This folder will need to be created with special permissions to ensure its consistency. It will need full permissions for writting new files for any user, and: * the sticky bit, so other users are allowed to read other user files, but aren't allowed to erase them * the setgid, so all the files copied to the image repository end up with oneadmin group This can be achieved with “chmod 3770 /path/to/image/repository/”. If you changed the images path, or if for some reason you deleted the var directory, you'll need to recreate the sticky bit configuration. In order to let other users register images, you have to either let anyone write in the images path, or add all your OpenNebula regular users to oneadmin's group. Could you please check your configuration? If you continue having troubles, please send us your installation directory permissions. Next step--to make a public non-persistent generic image in the repo, and then have a clone function such that a user can make a non-public persistent image from it and fork off their VM and save it from there on. Anyone else interested? What's your goal? to control it somehow in the VM template, or rather create a new command such as: oneimage clone Original_public_image My_private_copy ?

Re: [one-users] onevm create/deploy commands to send VMs to host of our choice (OpenNebula 2.0.1 and CentOS 5.5 with Xen)
Hi Prakashan, There are different options to control the placement of the VMs. If you want to manually deploy them, you can hold the VMs (onevm hold id). The scheduler won't place these machines, but you can still deploy them with onevm deploy. Or you could start only the OpenNebula daemon without the scheduler (take a look at the 'one' start script, and comment the ONE_SCHEDULER part). The other option is to use the REQUIREMENTS and RANK VM template attributes, see [1]. The scheduler will read them, and place the VM accordingly. You can require the VM to be deployed in a specific host or cluster; or modify the RANK expression to set the hosts priority. Regards, Carlos.

Hi,
If I'm understanding right, you first log into your VM, shutdown it
yourself, and then issue the onevm shutdown id.
Is this right?
onevm shutdown command assumes the VM is still running, and sends the ACPI
signal to the machine. Your virtualized OS is supposed to shutdown itself
with this shutdown signal.
If the VM Life Cycle is managed manually, OpenNebula will lose track of what
happened, that's why the VM is seen as UNKNOWN.

Hi Carlos.
A shutdown doesn't work for me. Even with 'acpi=yes' and a *graceful*
shutdown inside the vm (via vnc) the VM state always remains RUNNING
(ACTIVE) although it was already successfully removed by libvirt.
If I then manually execute onevm shutdown 345 (see [1]) the state
changed to UNKNOWN (ACTIVE). The onevm shutdown doesn't seem to affect
my vm, perhaps this feature is not supported by kvm? Therefore onevm
delete currently is my only option to trigger the image-hook.
What do you suggest?

Hi again, I haven't been able to reproduce the error, in either one 2.0 or 2.2 branches. Unless all vnets are public, the authorization rejects the new VM. On the other hand, we may have confused you with this documentation quote: Virtual Networks created by oneadmin can be used by every other user. That was how VNets were shared in OpenNebula 1.4. Since 2.0, oneadmin's VNets are shared using the 'onevnet publish' command, just like any other user's. The guide is now fixed, sorry for the confusion.

Hi,
As you pointed out, your client program has to copy or create the file, and
then enable the image.
The command oneimage already does that. You may want to check it (the binary
executable is actually a ruby script) and ImageRepository.rb

ID : 35

TYPE : OS
REGISTER TIME : 03/28 10:12:57
PUBLIC : Yes
PERSISTENT : No
SOURCE : /opt/nebula/images/afa5ebb70546e3786197e607b4092f1e13c5a5e4

RUNNING_VMS: 0
IMAGE TEMPLATE
DESCRIPTION=0328_mkImg_1 desc
DEV_PREFIX=hd
NAME=0328_mkImg_1
PATH=/one_images/8/images/disk.0
TYPE=OS
The file path to SOURCE Attribute,but the actual file isn't generated!
My java project code the following:
StringBuffer template = new StringBuffer();
template.append(NAME=).append(\).append(name).append(\).append(\n);
template.append(DESCRIPTION=).append(\).append(desc).append(\).append(\n);
template.append(PUBLIC = ).append(YES).append(\n);
template.append(TYPE=).append(OS).append(\n);
template.append(PERSISTENT=).append(NO).append(\n);
template.append(DEV_PREFIX=).append(\hd\).append(\n); // 可选.
//template.append(BUS=).append().append(\n);
template.append(PATH=).append(/one_images/).append(vminfo.getVmId()).append(/images/disk.0).append(\n);
Vector params = new Vector();
params.add(template);
RPCUtil util = new RPCUtil(this.imageDAO.getDataCenterIp(null));//get
opennebula ip/username/passwd
Object[] rsObject = util.executeRpcMethod(one.image.allocate, params);
if (!(Boolean) rsObject[0]){
runLog.error((String)rsObject[1]);
throw new BaseException(failed to image register!);
}
From opennebula.org document said：
When a new image template is allocated, the core will insert the image in
the system in DISABLED state. The developer has to request the extended
information for the new image, and copy (or create) the file to the
SOURCEattribute (added by the core). After the file is copied (or created),
the
image has to be enabled.
When I used the command oneimage register xxx.one ,the new image file
has generated!
Waiting for your reply!
Thanks and Regars！

Re: [one-users] Can't restart or resume VM when VM is in save status. And MEMORY = 0 when VM is running .
Hi there, If you take a look at the Virtual Machine Life-cycle diagram [1], the 'save' state is a intermediate state, and the VM should end in either the 'suspended' or 'stopped' state. If the VM is stuck in 'save', you may find some error messages in oned.log or the VM's log (in vm-id/vm.log). About #2, it may be a monitorization problem. Can you check using virsh or xentop the actual memory consumption? Best regards, Carlos.

Re: [one-users] how to predeploy image
Hi Łukasz, You could use the tm_dummy driver. That tm script returns always 0 and does nothing else. But using that tm_driver, you will have to manually move the files for all VMs, not just some of them. It would be best if you could modify the driver (tm_clone.sh, look for it in your lib location) to issue the mkdir and scp commands only if the destination file is not already present. It should be pretty straight-forward.

I want to predeploy an image so that the VM could start at the scheduled by haizea time. How can I predeploy a VM's image? I would appreciate clarification. I had several ideas how to make it work but I didn't succeed. 1. I tried to copy a prepared image to the default directory (/var/lib/one/VM-id/images/) in which it should be stored when a new VM is created. 2. Then I tried to do the same and to create transfer.0.prolog file (after reading one of the generated by opennebula) but it didn't work. 3. I tried even set the source in DISK section in VM template to the copied file in the destination. However, everytime I can see in VM log, that the image is copied.

Hi Ignazio,
This is a quick change to the simple_permissions.rb script. I didn't even
check if this works, but it should help you get the idea of what Daniel
proposed.
When modifying an authorization script, you have to take into account that
oneadmin (user with id = 0) is granted anything in the core.

You can use the auth module [1,2] to disable the VNet creation for
users different from oneadmin.
Furthermore, we are developing a new feature to mange user groups. You
will be able to set roles for different users and even customize your

Re: [one-users] Does the SOURCE make no sense when creating an image in opennebula-2.2.0
Hi, You are right about the steps made by the ruby OCA and OpenNebula daemon. And indeed, it makes no sense to specify only a SOURE attribute *if it is a file path*. But you can still take advantage of the SOURCE if you use an http:// url. This can be used to bypass the local Image Repository and store some of the Image files remotely. Anyway, this isn't the typical scenario, and maybe it still makes sense to remove the SOURCE option from the Suntone wizard.

So I go to the source code both in Ruby and opennebula, the SOURCE is only valid when using the PATH or SIZE(with FSTYPE). In my opinion, the whole image creation consists of four steps: 1. Sunstone-server sends one.image.allocate by using Ruby to opennebula. The opennebula receives the calls and checks if the SOURCE exists in parameters of the image template. If it does not exists, opennebula assign a string to the SOURCE with the SHA1 digesting of uid:name, otherwise do nothing to the SOURCE. Then, inserts a image record into the DB. 2. Then sunstone-server sends one.image.info to opennebula to retrieve the initialized infomation by step 1, mainly the value of SOURCE. 3. Suntone-server starts to judge the branches by PATH, SOURCE, SIZE, FSTYPE and TYPE. When there only exists the SOURCE, it will do nothing. (For example, if the PATH exists and SOURCE not exists, it will do copy the PATH file to the SOURCE file path, and etc.) 4. If former steps have no errors, sunstone-server sends one.image.enable to opennebula, it just update the record in DB and do nothing about the SOURCE. Otherwise, it sends one.image.delete to opennebula and delete the record in DB. So, if just specify the SOURCE to create an image, the operation make no sense. So, I think the SOURCE input should be removed in web pages of sunstone-server . If I have mistakes, please send me the error correction.

Re: [one-users] Java OCA: poor choiche of Exception class
Hi there,
The RuntimeException looks better to me.
The only thing I'm not sure about is why you deleted the 'throws'
declaration from Client.java.
Doing that, a client application is not forced to catch the connection
problem.
I think it's better to force the coder to be aware of this kind of problems,
and prepare a nice error dialog, or a re-try mechanism.
What do you think about using the RuntimeException and
'public Client() throws OpenNebulaConfigurationError' ?
Best regards,
Carlos.

Hi Nikolay, The life-cycle diagram [1] is the best way to understand the VM states, and what actions are available for each of them. If you shut down a VM, it will enter the final DONE state, from which no action can be performed. A stopped VM on the other hand can be later resumed, using 'onevm resume'. Internally, the difference is that shutting down the VM it has a chance to perform any operations (like unregister from a service). A stopped VM is suspended (paused).

Re: [one-users] VMs still reported as running although host is down
Hi Steffen, There are two reasons I can think of that can cause that behaviour: 1) The next monitoring cycle hasn't been triggered. 2) The monitorization was triggered, but the command crashed and it didn't return neither FAILURE or SUCCESS to the core. I've made a couple of tests and found that, indeed, there is a bug :/ You can its ticket here [1]. The problem is that the core sends the monitoring request to the ssh driver, and it is supposed to return FAILURE or SUCCESS. Instead, the driver is crashing, and the Host and VM keep the last monitoring data (and status). This could also cause trouble if the motorization probe gets stuck, and doesn't end its execution. We are aware of this problem, and we intend to add timeouts and checks to the drivers to ensure that the actions are always answered to the core. Thanks for the feedback! Carlos.

Re: [one-users] How config Windows vm template?
Hi there, The contextualization offered by OpenNebula is creating that cdrom and context.sh script, but it's up to the guest OS to read that file and configure itself. We only provide linux scripts; you would have to create similar ones. I'm not sure how difficult that can be since I don't have experience with Windows scripting. If you only need to configure the right IP for your VM, then you can try to configure a DHCP server in your network (it can be placed in a VM in the same VNet).

Dear ONE developers,

For more details please see [1].
As far as I understand from
$ONE_LOCATION/var/remotes/vmm/hypervisor/restore files ONE invokes restore
script only with one argument which is the dump file.
I am using XML type of VM_MAD driver in oned.conf (as below) to perform all
actions on OpenVZ VMs:
-8-
VM_MAD = [
name = vmm_ovz,
executable = one_vmm_ssh,
arguments = ovz,

---8
I wonder what file needs to be change to invoke restore script on remote
node with one more argument ($deploy_id) needed for OpenVZ hypervisor (it
looks for me that such approach should be safe for other hypervisors since
they takes into account only the first argument).
Thanks!

Re: [one-users] '-' or 'err' (instead of 0) as a value for parameters which ONE fails to get
Hi Nikolay, The memory and cpu are numeric attributes managed by the core, initialized to 0. If the driver doesn't report them, they are not updated. The way I see it, the drivers didn't know how to populate the values, rather than encounter an error monitoring them. We could modify the core to initialize them with -1, and make the CLI show 'unk' or '-'. But to me it makes more sense to report always a positive value, since the data can be consumed by other applications, and dealing with the special case of -1 (or 'err' if the data is read from the onevm output) can introduce bugs.

The template attributes are sorted in alphabetical order, so you can assume
a fixed order, but you can't be sure about what child elements will be
present since the template may contain anything.
You could however assume the contents if you force the VM creation to be
only done using your OVF to OCA server; or if you limit the VM information
retrieval to work only for VMs created from your code.
And does this hold even for the content of DISK, NIC and
OS?
Even inside each vector attribute, its sub-attributes are ordered
alphabetically.
Common sense says that Ruby should not execute its instruction
out of order, so the order is fixed and some elements may or may
not appear, but the order should not change. Can you confirm
this ?
Yes, after doing some tests it looks to me that the XML is not modified in
any way by Ruby.
Best regards,
Carlos.

Re: [one-users] Running FE as Xen dom0/domU?
Hi Richard, On Mon, May 23, 2011 at 4:09 PM, Richard Palmer richard.d.pal...@kcl.ac.ukwrote: The servers are all fairly powerful so I don't want to waste one just running the FE on it. Can I run the FE code in dom0 (in Xen) and also add the same server as a host to Nebula?. Or would it be better to create a domU just to run the FE code in, but still add the host to Nebula ?. The FE can be added as a Host just fine. We would advise to install OpenNebula in dom0, since there's no clear advantage to an installation inside a VM. It will save you some network configuration, and you avoid a possible performance downgrade. You may however have some good reasons to install OpeNebula in a domU. For instance, your servers may have an old OS and you find it difficult to install the required dependencies. In that case a virtualized recent distribution will be easier to set-up. Or if you have big plans for your domU OpenNebula like migration to new HW, or High Availability setups. In that case, keep in mind that the VM must be able to see the other Hosts in your network, attaching its interfaces to a bridge in the private physical interface. You should also configure an external NFS server. Can (or should) long running servers be managed through Nebula ? E.g. a blog server. I'd like to have a single view of all the servers so creating them all via Nebula would be useful, but perhaps it's not really meant for this. Yes, OpenNebula can and should manage all VMs, because it assumes exclusive usage of the physical resources, and managing VMs manually may lead to IP collisions. Moreover, OpenNebula is well suited for long running servers. You can take advantage of the Fault Tolerance features [1] to resubmit a crashed VM, or even resubmit the VM in another Host if the first one fails. And, if the server running OpenNebula fails, it will continue the monitoring and management of the VMs when it is restarted. Can any requirements beyond memory and disc be specified for an instance ?. E.g. must have access to tape library attached to only one of the hosts. You can define any placement requirement. If you need a specific Host, REQUIREMENTS = NAME = myhost or you can group some Hosts in clusters [3], and require the VM to be deployed in any of them: REQUIREMENTS = CLUSTER = development Best regards, Carlos.

Re: [one-users] Restarting a vm instance after shutdown?
Hi Lars, We think the model you are describing will be easily achieved in the upcoming 3.0 [1] release. The approach we are taking to implement persistent VM is making the VM Template the main VM entity, as you pointed out. With the new VM Template pool, you will be able to: (a) A vm instance would start with its own copy of a disk image. A new 'oneimage clone' command will provide a personal private copy of another Image. Then, a VM Template using that Image can be registered using 'onetemplate create my_vm.one' (b) Shutdown would not delete the image. The data won't be lost if the Image is persistent. Which I think is a reasonable default for an Image created from 'oneimage clone'. (c) Some command (restart, or resubmit, or something) would allow one to restore a vm instance that had been shut down. A VM instance will finish it's life-cycle after shutdown, this won't change. But the VM Template will be still available in the pool, and can be instantiated many more times. (d) Disk data would only be discarded with an explicit delete. There will a explicit delete for the disks (oneimage delete), and for the VM Template (onetemplate delete). Best regards, Carlos.

(d) Disk data would only be discarded with an explicit delete. Ideally, this would be controlled at the virtual machine level, not the disk image level. That is, one would set the don't delete on shutdown option on the vm instance. The problem with persistent images is that -- as far as I can tell -- the vm instance references the image in the repository directly, rather than getting private persistent *copy* of the image. The problem with saving a vm instance is that it doesn't really address the problem of, whoops, I typed the wrong vm id and shutdown the wrong system. It also forces the template description file to become more important, since the recovery process is to create a new virtual machine instance, rather than rebooting the old one. I have seen several similar questions on the list from folks looking for a way to support persistent virtual machines, so it looks as if this is a model for which there is some demand. For those of you familiar with the codebase, does this look as if it would be hard to implement? If I wanted to implement it myself, should I be looked at the 2.4 code?

Apart from possibility to be aware of $SCRIPT_REMOTE_DIR value the tm_clone.sh script needs to know the name of OS image to be used for VM deployment and that is a problem. Let me briefly explain what I mean. To create new VM on OpenVZ host there are two options: 1) one can specify using 'ostemplate' option the name of already existing so called OS template which has to be available in predefined dir set in TEMPLATE variable of OpenVZ global config file (by default it is /etc/vz/vz.conf). Normally TEMPLATE=/vz/template and OS template has to be available in $TEMPLATE/cache. There is no way to specify the absolute path to OS template (like --ostemplate=$VM_DIR/$VMID/images/disk.0 replacing the variables $VM_DIR and $VMID by their values e.g. --ostemplate=/vz/one/vm/55/images/disk.0). One of the example of a proper command could be as $ vzctl create 101 --ostemplate centos-5-x86 and OpenVZ expects the existence of the /vz/template/cache/centos-5-x86.tar.gz file with corresponding name. 2) one can skip --ostemplate option. Then OpenVZ will use the default OS template name defined in $DEF_OSTEMPLATE variable in /etc/vz/vz.conf. But that way is not very flexible (althrough it can be followed if all VMs are going to be deployed using only single OS template and thus its name can be redefined ones during initial OpenVZ host configuration). To follow the first option I would implement the logic as described below: 1) get the name of OS template specified in config file for given VM; 2) check if OS template with same name already exists in $TEMPLATE/cache dir. If it does then rename it, create a symlink (or one can copy it) from $VM_DIR/$VMID/images/disk.0 to $TEMPLATE/cache; 3) create VM; 4) remove symlinked OS template images from $TEMPLATE/cache dir. But tm_clone.sh script is executed before $SCRIPT_REMOTE_DIR/vmm/ovz/deploy script and hense the VM config file is not yet available to retrieve OS template name. Moreover the fourth step (OS template deletion from $TEMPLATE/cach dir) needs to be executed after VM creation. So all the steps described above needs to be implemented in $SCRIPT_REMOTE_DIR/vmm/ovz/deploy script although such approach in some sense mixes functionality which each script was initially intended for (as far as I understand it).

Re: [one-users] Does OpenNebula work or replace VMware vCenter?
Hi Florian and all, thanks you for your comments. Although Tino is the main VMware driver developer and he will be able to provide more low-level details, let me say some words to clarify how OpenNebula compares with VMware products. OpenNebula 2.2 can be used on top of VMware ESX and vCenter. - On top of ESX, OpenNebula provides all its features for public/private/hybrid cloud and virtualized data center management (http://opennebula.org/documentation:features) - On top of vCenter, OpenNebula can orchestrate several vCenter instances and offers cloud functionality not offered by vCenter: multi-tenancy, VM provisioning, cloud interfaces (EC2 and OCCI), public/hybrid cloud computing… so there are many benefits from using OpenNebula 2.2 on top of vCenter. vCloud Director is the new VMware product that on top of vCenter offers cloud functionality, mainly multi-tenancy and cloud API (vCloud). The functionality for grouping users and creating virtual data centers is something provided by vCloud that is not offered by OpenNebula 2.2. However, OpenNebula 3.0 (due in 2 weeks), and its powerful ACLs management, will offer much richer functionality for grouping users, creating projects, defining different levels of administration, managing virtual data centers…. Summarizing, you can replace vCenter with OpenNebula if you want a more cost-effective, open, standard-based, flexible and hypervisor independent solution. However given that OpenNebula provides a management layer with hypervisor independence, there may be VMware specific functionality that is not leveraged by OpenNebula. You can also use OpenNebula on top of vCenter, but I think that in such a case, OpenNebula should have full control over vCenter and you should manage the cloud through the OpenNebula interfaces. Finally, OpenNebula 2.2 is not ready to replace vCloud Director, but this will be solved in OpenNebula 3.0. Please let us know if you need further information.

But, with OpenNebula 3.0 many of the missing features are implemented and as far as I could test them, OpenNebula seems to be a good / cost efficient choice to replace vCenter. Integrating OpenNebula with vCenter and usage of ESX is possible, but from my point of view this is only valid as a migration path to replace it with a KVM or XEN infrastructure. If you have a production setup where a downtime of your service costs a lot of money, then you're probably better off with vCenter and buying all their licenses. If you want to provide a cheap IaaS plattform, then OpenNebula 3.0 could be right for you. BTW: From a recent comparison of OpenNebula 3.0 and the current version of OpenStack I got the impression that OpenNebula will be better suitable for IaaS environments.

I have read through some documentations as well as the VMware Driver Addon guide. But I still not quite understand many basic aspects of OpenNebula, particularly: 1) What's the position for OpenNebula in a VMware based platform that vCenter already exists? 2) Our Enterprise Plus license gives us full features of the vSphere platform, work with the vCenter, does OpenNebula interact with those features as well? I'd keen to hear from anyone who has the experience on this. Thanks in advance. Derrick ___ Users mailing
Re: [one-users] OpenNebula test data
Hi there, I'm not aware of any study focused on finding the OpenNebula limits, but in this link [1] you can see a large scale deployment at CERN managing up to 16,000 VMs Regards, Carlos.

Re: [one-users] creating VMs
Hi, You don't have to create an OpenNebula-specific VM format, you can use your existing VM images or follow any tutorial for your chosen hypervisor. After you manage to create and deploy a VM for your hypervisor, you have to contextualize it in order to make the OpenNebula network management work. See this guide [1] for more information. Or you can download the sample VM we provide [2] in order to test your installation before you create your own VMs. Regards.

Re: [one-users] Long Running Servers
Hi Richard, The template you propose looks fine, but let me make a couple of comments. Instead of 'source' and 'save' for DISC, you should use the Image repository, and take advantage of the persistent flag [1] to make sure the contents are saved. This way you can forget about the 'save', 'clone' and 'readonly' attributes. And just in case, when you say to ensure it keeps its state between restarts, keep in mind that a onevm shutdown command will save the disk, but not the VM state (RAM). If that's what you need, take a look at the suspend and cancel commands [2]. Please also note that onevm restart will not start over the life cycle of a VM, it is a way to resubmit the booting command to the hypervisor in cases when the VM gets stuck in the BOOT state. To continue the execution of a VM you previously shut down, you have to create a new VM instance from the same template file. Best regards, Carlos.
