Re: [one-users] HOWTO: various questions about open nebula
Title: Thanks 1. Yes, we can have deferred and hot snapshot. Deferred means backup is done when you shutdown the VM, hot means a live snapshot. 2. I haven't tested it yet, but you can manually zip an image. If you saved it as qcow2 and it is empty, file size is small. 5. On a normal install, you need to boot the VMs again on another node if their original node goes down.

Re: [one-users] reupload RBD images
Thank you very much. I knew there is a way like that but I don't
know the syntax. I was desperate reuploading qcow2 images to rbd.
Thank you again.

I'm not sure what opennebula
will do if there is already a ceph rbd image with the name that it wants
to use when creating a new image - however there is a safe, if a bit
more laborious way to do it... 1) Rename all the images in ceph for
safety before you start: rbd mv one-1 one-1-orig 2) Create new images
from opennebula, using the same specs you used to create the original
ones. You should now see 'one-1' etc in ceph. It doesn't matter what the
images contain (i.e. they can be empty) but you should make sure to
create them with the same name, type, size, persistence etc. 3) Stop
opennebula to prevent any more changes 4) Delete the empty images in
ceph (Make sure you're not deleting the originals here!): rbd rm one-1
5) Move the original images back to the corresponding names: rbd mv
one-1-orig one-1 6) Restart opennebula Hope this helps! Matthew -- The

Re: [one-users] upgrade to 4.4, system datastore problem
Hi,
I was able to upgrade to 4.4. Right now I have only a single
host running. CEPH datastore for images. I can't instantiate any of my
previous images. Right now the only way to instantiate images is via a
new upload or through market place. I think the problem is the system
datastore. Previously, I am using the ceph-fuse as the shared system
datastore.
I can't start sunstone server when I use the ceph-fuse. Can
somebody explain how I can have a shared system datastore and possibly a
way to use ceph for it? I don't want to use NFS.
Thanks.

It's weekend, people are out of their computers (maybe). Are you sure sunstone server is not being started when you reboot? It should be as launched at startup like the one service, you could have made some mistake during the installation? That being said, I'll make a bash script which contain the lines.

Re: [one-users] Ceph and thin provision
I haven't tested much on non-persistent image as I have no use on them unless on experiments. Also, I haven't tried any volatile image, sorry. _A not persistent image is writeable?_ Short answer: NO Long answer: Yes, sort of. When you instantiate a non persistent image, nebula create a another disk in the background temporarily. You can check that on when you issue rbd ls -p one. You'll see something like this. one-34 --- this is the non persistent image disk one-34-73-0 this is the temporary clone of the disk when you instantiate a VM one-34-80-0 - another VM which uses the non persistent image one-34 This is why you can instantiate two or more VMs using a non-persistent image. If I'm not mistaken, the temporary disk will be destoyed once you shutdown the VM from nebula sunstone. But as long as the VM is running, the data is there. You can even reboot the VM with non-persistent disk and still have data. You lose the data once Nebula destroys VM disk, that is, when you SHUTDOWN or DELETE the VM from nebula sunstone. As for thick and thin provision, all of my images in ceph are thick, because my base image is 25 GB disk from a KVM template and then I imported it in ceph (it was converted from qcow2 to rbd). It consumes whole 25GB on my ceph storage. I just clone that template image every time I deploy a new VM. I haven't tried creating a thin or thick provision in ceph rbd from scratch. So basically, I can say that a 100GB disk will consume 100GB RBD in ceph (of course it will be 200GB in ceph storage since ceph duplicates the disks by default). --- Thanks, Kenneth Apollo Global Corp.

So I can have a real hdd of 250gb with inside ten virtual thin disks of 1000gb each, if they are almost empty. I have checked again and ceph rbd are thin.

Re: [one-users] Ceph and thin provision
This all is good news. And I think this will solve my problem of a bit slow (a few minutes) of deploying a VM, that is cloning is really time consuming. Although I really like this RBD format 2, I'm not quite adept yet on how to implement it in nebula. And my ceph version is dumpling 0.67, does it support rbd format 2? If you have any docs, I'd greatly appreciate it. Or rather I'm willing to wait a little longer, maybe on the next release of nebula(?), to make rbd format 2 to be the default format? --- Thanks, Kenneth Apollo Global Corp. On 12/12/2013 09:48 PM, Campbell, Bill wrote: Ceph's RBD Format 2 images support the copy-on-write clones/snapshots for quick provisioning, where essentially the following happens: Snapshot of Image created -- Snapshot protected from deletion -- Clone image created from snapshot The protected snapshot acts as a base image for the clone, where only the additional data is stored in the clone. See more here: http://ceph.com/docs/master/rbd/rbd-snapshot/#layering [2] For our environment here I have modified the included datastore/tm drivers for Ceph to take advantage of these format 2 images/layering for Non-Persistent images. It works rather well, and all image functions work appropriately for non-persistent images (save as, etc.). One note/requirement is to be using a newer Ceph release (recommend Dumpling or newer) and newer versions of QEMU/Libvirt (there were some bugs in older releases, but the versions from Ubuntu Cloud Archive for 12.04 work fine). I did submit them for improvement prior to the 4.0 release, but the simple format 1 images are the default currently for OpenNebula. I think this would be a good question for the developers. Would creating the option for Format 2 images (either in the image template as a parameter or on the Datastore as a configuration attribute) and then developing the DS/TM drivers further to accommodate this option be worth the effort? I can see use cases for both (separate images vs. cloned images having to rely on the base image), but cloned images are WAY faster to deploy. I have the basic code for format 2 images, I think the logic for looking up the parameter/attribute and then applying appropriate action should be rather simple.

Re: [one-users] How to use ceph filesystem
The first requirement is that the front end node is able to communicate with the ceph cluster. Veriy it by loggin in as the oneadmin user and issue the command ceph -w. The ceph cluster shoul respond HEALTH_OK. Then define it as a datastore in openebula as an image datastore. No further confiuration needed and when you uplaod images to he front end, you should choose the ceph image to save the omages in rbd format.

Re: [one-users] How to use ceph filesystem
Going directly to RBD layer will be used once you use ceph as IMAGE datastore. Nebula will be interfacing directly with ceph and your images will be in RBD format.This is already the direct way. This is the same things as using KVM with ceph RBD. The only thing you may want to use is the cephfs (which is not RBD) is when you use it for the SYSTEM datastore and use shared for TM. This is what I use. Besides, system datastore does't contain a lot of files so if this method is inefficient, I won't notice it all. But if you also want to use RBD for the system datastore, you can still use it. You just mount an RBD image in the /var/lib/datastore/0/ of you nodes. --- Thanks, Kenneth Apollo Global Corp.

Thanks, Mario 2013/12/3 Jaime Melis jme...@c12g.com Hi Mario, Cephfs CAN be used a shared filesystem datastore. I don't completely agree with Kenneth's recommendation of using 'ssh' as the TM for the system datastore. I think you can go for 'shared' as long as you have the /var/lib/one/datastores/... shared via Cephfs. OpenNebula doesn't care about what DFS solution you're using, it will simply assume files are already there. Another thing worth mentioning, from 4.4 onwards the HOST attribute of the datastore should be renamed as BRIDGE_LIST. cheers, Jaime On Tue, Dec 3, 2013 at 11:28 AM, Kenneth kenn...@apolloglobal.net wrote: Actually, I'm using ceph as the system datastore.

You can of course. But it is up to you to monitor. And using storage on different hosts will cause the VMs to be copied via scp which is pretty slow. Another way to have a large storage is to remove other drives on the nodes (or use small drives in them) and then plug big capacity drives on the main NFS node.

[one-users] recover the RBD
So I have a about 20 images stored in a ceph image datastore and the pool name is one. I understand that the disk images are in RBD format now. I want to migrate a VM, say image is one-23, to another KVM host. It is just a plain Ubuntu server KVM host and not a member of the OpenNebula cloud or Ceph cluster. Is there a way to convert and image from the Nebula (or from ceph rbd) to .qcow2 format or to .raw format? I want to import the image to the new KVM host using Virt-Manager utility in Ubuntu. -- Thanks, Kenneth ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
Re: [one-users] How to connect to VMs
What Network model are you using when you create Virtual networks - Default, 802.1Q, ebtables, Open vSwitch etc? Try Default first, then define the Bridge interface of your OpenNebula hosts such as br0 or br1. You should know already that the network interfaces of the hosts nodes of OpenNebula is bridged. On the virtual network, define your IP range of 192.168.42.x IPs. Assign this Virtual network to your VMs. (You may need to configure you VM to use this address).

[one-users] upload using command line
Hi all, I have here a 32GB .raw image of ubuntu 12.04 that I want to upload to opennebula. I don't want to wait a lot uploading the image using the OpenNebula sunstone interface. And since my OpenNebula front end has no hard drive, I figured that I would attach an external hard drive to it containing the 32GB imgae. Then, while the external hard drive is mounted, I would like to upload the image using the command line as oneadmin. What is the syntax to do this? I'm also using a ceph datastore to store the images, so in case there are some arguments to be changed on the command, kindly enlighten me. Thanks a lot. -- Thanks, Kenneth ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] Virtual network requirement?
Can i create a VM without declaring a network IP for it in Open Nebula sunstone? I mean, if I set a VM on sunstone to use 192.168.1.15 with br1 (in the Virtual networks in the section), and the Ubuntu VM boots up (default is dhcp in ubuntu), the IP that is going to be assigned in the VM is the one assigned by my DHCP server. For example the IP that will be given to the VM by the DHCP server will be 192.168.1.10. The 192.168.1.15 doesn't make sense at all. What's worse is that the VM will not be able to connect to my LAN if it's IP is 192.168.1.10. I need to *change it manually* so that the *IP in sunstone* is the same as the *IP set in the VM* to be able to communicate in my local LAN. It's an extra step to define a network first and then define again in the VM. Any workaround on this? Can't I just decalre an IP to the VM itself and not in sunstone? -- Thanks, Kenneth ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Re: [one-users] Working with Ceph datastore - How to tell do linked snapshot for new VM?
Are you cloning/uploading an existing image to open nebula?. I'm using ceph datastore too. My kvm template image is a 21GB qcow2 (and raw) image but only 1.5GB of space is taken up. (that is before uploading to nebula). Images that will be stored in ceph will be converted to RBD and when nebula sees that a this disk is 21GB, it will be allocated. The allocation time will depend on how fast your ceph network is. And have you tried creating an empty datablock? Create an empty datablock in the ceph datastore and then install linux on that datablock, the allocation of an empty datablock is faster, though you'll need to install the OS afterwards.

Re: [one-users] Error creating VM opennebula 4.2
No, it's not about the double slashes. Some pointers: - be sure the system datastore (default datastore 0, located in /var/lib/one/datastores/0/) is a common folder shared by the front-end and the nodes. It can be a mounted nfs. - be sure the the image datastore (default datastore 2) or your own declared image datastore is also a common folder shared by all nodes.

[one-users] Cannot contact server: is it running and reachable?
Hi all, I just installed OpenNebula a few days ago. It is running fine, but every minute or so this message appears on the lower right of the OpenNebula webmin page. It is a notification bubble. It also appears when I used the KVM sandbox from the opennebula website. Now that the front end is in a seperate physical machine, the notification still appears. Error Cannot contact server: is it running and reachable? Although the notification appears, all features (as far as my testing go) are working as expected. No errors yet. Should be alarmed of this message? Is there a way to remove this notification. I don't want my boss to see this notification when the cluster is in production environment. Thanks! -kenneth ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
