Re: [one-users] fibre channel datastore
Hello Jaime, thanks for your tips on configuring the LVM datastore. I gone through all the steps and I have configured datastore. Next problem is that I can not understand why my virtual machines are not being provisioned to this new datastore. Thanks.

No. You don't need to (you could, but there's really no point). 2. Which driver should I use on compute nodes ? The LVM drivers. 3. Will my virtual machines be persistent during infrastructure reboots ? Yes. The similar setup you have described is exactly what you want to replicate with OpenNebula. You need the LVM drivers for this. I have just added a diagram to the LVM guide [1] to show you exactly the setup you need. The idea is to export the same LUN to all the OpenNebula nodes and create a cLVM* on top of it. OpenNebula will speak to just one of the nodes of that cluster ($HOST parameter in the Datastore template). If the FC configuration is persistent, and the cLVM configuration is also persistent, then your VMs will persist during reboots. Note that the underlying storage doesn't affect OpenNebula at all, you could do this with FC, iSCSI, or even a NAS, as long as you export the same block device to all the hosts (are configure it to persist after reboots). By the way, I strongly recommend reading this article, written by the people at MTA SZTAKI, explaining many things about LVM deployment. You will find a lot of hints, best practices and troubleshooting tips in there. * Maybe you don't need cLVM, after reading the article [2] you will be able to understand the pros and cons of using it.

I already had similar setup but with plain libvirt and kvm, the concept was to use one lun per datastore from fc storage using fc hba and switch, which was advertised to compute nodes as lvm vg, then each virtual machine had 1+n logical volumes from this vg as its hard drive.

[one-users] Setting CPU overcommit globally
Hi all, In our environment, we need to overcommit the CPU in every host. We have 6 host running KVM, on Ubuntu 12.04 Our Opennebula is 3.8.1 Previous discussion about CPU overcommit is suggesting that I have to put CPU=0.5 and VCPU=2 to get 1 real CPU overcommit as 2 CPU, to each VM template. Is there any way that I can just set it once, and when I launch/relaunch a VM, it will be automatically CPU overcommit, without having to change the VM template? Thanks. -- Sharuzzaman Ahmat Raslan ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] RFC: Feature idea - Image preparation
Hello All, Before I was using Open Nebula, my general virtual machine workflow was as follows: 1) Install OS to qcow image, this creates an image between 500-1500MB 2) Unconfigure virtual machine, e.g. remove any system specific config: udev rules, user accounts, ssh host keys, SELinux relabel etc. 3) Zero out the file system by creating a large file of all zeros, e.g.: dd if=/dev/zero of=./delme; rm delme 4) Compress and (qemu-img reclaims unused space while compressing so the sparsify is implied) the image, to create a master image (I've heard this referred to as a golden image) this typically results in an image between 300-500MB, e.g. qemu-img convert -c -f qcow2 master.qcow2 -O qcow2 master.compressed.qcow2 5) Create a slave copy on write image off the master, e.g.: qemu-img create -b ../master/master.compressed.qcow2 -f qcow2 ./virtualmachine.qcow2 This results in all of the changes being written to ./virtualmachine.qcow2 Fortunately, virt-sysprep and virt-sparsify handle steps 2 and 3 and the sparcify part of step 4 more or less mindlessly. qemu-img is still required (as far as I know) to compress the image, but there is no longer a need to be in the vm to zero out the image, so this whole process can be automated through a management layer like OpenNebula. I would like to automate this work flow through OpenNebula. I think it would be extremely useful to be able to prepare and finalize a virtual machine from OpenNebula. Finalizing an image in this manner allows for maximization of disk space as well as use as a master or golden image. In my mind, I think it makes sense to use the least amount of space for the common filesystem pieces. Basically, when I create a new image in OpenNebula, I create a template with the iso and a blank persistent datablock, then instantiate the vm, install the iso, shutdown the vm, and flip the image to a nonpersistent OS. What I am proposing is a feature that would add an additional step that would allow a user to finalize the vm by virt-syspreping, virt-sparsifying, and compressing the image, to maximize space usage. -- My goal is to have a cli command, e.g.: `onevm finalize 38` or `onevm finilize ubuntu-server-13.04` as well as an option in Sunstone to finalize the image. It would effectively finalize and clone the vm so, if necessary, the original can still be modified and finalized again. Does any one have any other ideas, thoughts, comments, or suggestions for an image finalization function? Is there anything I'm not thinking about that I should be? As far as development of the feature is concerned, where would I create this feature for a commandline function, can you point me at some useful documentation for developing this kind of feature? I'm not ready to tackle the sunstone piece of this yet I don't think, so I think my focus will be on the command line function for now.
