oVIRT / GlusterFS / Data (HA)
by Devin Acosta 25 Jan '17

25 Jan '17

I have created an oVIRT 4.0.6 Cluster, it has 2 Compute nodes, and 3 Dedicated Gluster nodes. The Gluster nodes are configured correctly and they have the replica set to 3. I'm trying to figure out when I go to attach the Data (Master) domain to the oVIRT manager what is the best method to do so in the configuration? I initially set the mount point to be like: gluster01-int:/data, then set in the mount options "backup-volfile-servers=gluster02-int:/data,gluster03-int:/data", so I understand that will choose another host if the 1st one is down but if i was to reboot the 1st Gluster node would that provide HA for my Data domain? I also configured ctdb with a floating-ip address that floats between all 3 Gluster nodes, and I am wondering if I should be pointing the mount to that VIP? What is the best solution with dealing with Gluster and keeping your mount HA? -- Devin Acosta Red Hat Certified Architect, LinuxStack 602-354-1220 || devin(a)linuxguru.co

oVirt installs 3.6 repos for 4.0 compat cluster
by James 24 Jan '17

24 Jan '17

Hi guys, I'm trying to servers to a new oVirt 4.0 cluster. I've upgraded the engine (not hosted, standalone) to version 4.0.6.3 and run engine-setup and everything seemed to go fine. When reinstalling oVirt on a host after removing it from the 3.6 compat cluster into a 4.0 compat cluster causes issues when reinstalling and setting up the management network for some reason. I haven't been able to track this issue down fully yet. Whats weird is that even when a fresh new host is installed and added to the grid for some reason oVirt installs the repos for oVirt 3.6 on the host. I'm sure this is done by oVirt itself since they aren't there before I install the host and we don't manage these outside of that. It also just stalls at "Activating" the host and I can't do anything with them after that. Shouldn't it be installing version 4.0 for this cluster? I've triple checked its set to version 4.0 compatibility and the data center its in is also set to this level. Unsure what logs I can provide but any help would be greatly appreciated! Cheers, James

Updated Invitation: Next-generation Node package persistence for oVirt 4.1 @ Thu Jan 26, 2017 9am - 10am (MST) (users@ovirt.org)

This event has been changed. Title: Next-generation Node package persistence for oVirt 4.1 oVirt Node is a composed hypervisor image which can be used to provision virtualization hosts for use with oVirt out of the box, with no additional package installation necessary. oVirt Node is upgraded via yum in an A/B fashion, but the installation of a completely new image means that packages which have been installed on a previous version of the hypervisor were lost on upgrades, or required reinstallation. With oVIrt 4.1, oVirt Node will cache and reinstall packages installed with yum or dnf onto the new image, ensuring that customizations made by users or administrators are kept.

[PySDK v3] Choose storage domain
by Nicolas Ecarnot 24 Jan '17

24 Jan '17

Hello, When trying to create a VM by cloning a template, I found out I couldn't choose the target storage domain : [...] vm_storage_domain = api.storagedomains.get(name=storage_domain) vm_params = params.VM(name=vm_name, memory=vm_memory, cluster=vm_cluster, template=vm_template, os=vm_os, storage_domain=vm_storage_domain, ) try: api.vms.add(vm=vm_params) [...] I'm getting : Failed to create VM from Template: status: 400 reason: Bad Request detail: Cannot add VM. The selected Storage Domain does not contain the VM Template. ... which I know, but I thought that, as with the GUI, I could specify the target storage domain. I made my homework, and I found a nice answer from Juan : http://lists.ovirt.org/pipermail/users/2016-January/037321.html but this relates to snapshots, and not to template usage, so I'm still stuck. May I ask an advice? -- Nicolas ECARNOT

packages that can be updated without maintening hosts
by Nathanaël Blanchet 24 Jan '17

24 Jan '17

Hi The update notifier in the webadmin was originally designed to alert for new vdsm* packages. Now, I noticed that available update of virt packages and more are notified. I know that hot updating qemu-kvm package does break vms that are running on concerned hosts, but what about other one like libvirt-client? I know it is recommended to put in maintenance while updating, but can we update some minor packages without waiting for migration? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr
