Re: [one-users] Vlan template
2013/5/20 Jaime Melis jme...@opennebula.org: However, you can only tag one VLAN per interfaces, which as far as I know, is the only thing that makes sense? Why? Trunk interfaces carries multiple vlan, is absolutely standard. I have not less than 58 VLANs on a single interface on my XenServer host. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] fibre channel datastore
Hello, I have to setup proof of concept cloud using opennebula and zfs san. I can not understand the correct scenario of running virtual machines from FC: 1. Do I have to connect the FC datastore to opennebula server ? 2. Which driver should I use on compute nodes ? 3. Will my virtual machines be persistent during infrastructure reboots ? 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. Backup was performed via lvm snapshot and dd/rsync. There was a possibility to migrate storage from one node to another without vm downtime using virsh block-copy --live. What are the correct steps to achieve the same functionality on opennebula 4.0 ? I'm running CentOS 6.4 both on opennebula server and compute nodes. Thanks in advance! ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Re: [one-users] fibre channel datastore
Hello Denis, 1. Do I have to connect the FC datastore to opennebula server ? 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.

[one-users] OpenNebula 4.0.1 Released!
Dear OpenNebula users, The OpenNebula project is proud to announce the general availability of OpenNebula 4.0.1 [1]. This is a maintenance release that fixes bugs reported by the community after 4.0 was released. This release only includes bug fixes and it is a recommended update for everyone running any 3.x. or 4.0 version of OpenNebula. This maintenance release fixes several bugs of the new sunstone interface, and incorporates a mechanism to recover VMs stuck in a transient state. Check out the OpenNebula 4.0 Eagle release notes [2] for the release highlights and a summary of the new features incorporated in OpenNebula 4.0. Hope you enjoy using it as much as we did developing it ;) Best, The OpenNebula Project [1] http://opennebula.org/software:rnotes:rn-rel4.0.1 [2] http://opennebula.org/software:rnotes:rn-rel4.0 -- Join us at OpenNebulaConf2013 in Berlin, 24-26 September, 2013 | www.opennebulaconf.com -- Constantino Vázquez Blanco, PhD, MSc Project Engineer | OpenNebula - The Open-Source Solution for Data Center Virtualization www.OpenNebula.org | @tinova79 | @OpenNebula ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
