------ENLJO7GAMXWYZM97AQNB5AQA5DYU0F Content-Transfer-Encoding: 8bit Content-Type: text/plain; charset=UTF-8 Hi all, I'm trying to understand what is the meaning of the overcommit and usage percentage values shown in dashboard. For examlle, for the cpu, documentation simply states that indicates the ratio of virtual/physical cores available to "running" VMs. I have the following cpu values: 86% available of 100% Overcommit: 38% (allocated 63%). Bug 1402007 mentions that overcommit (although misleading term) indicates the physical resources allocated to running VMs. While "allocated" is the total physical resource allocated to provisioned VMs, running or not. Still why 86% available? What is the math behind it? Thanx, Alex -- Sent from my Android device with K-9 Mail.

ovirt-engine-rename after restore
by Sergei Genchev 28 Jan '17

28 Jan '17

Hi, I am trying to upgrade ovirt from 3.6 to 4.0. I have backed up configuration on current CenTOS6 oVirt 3.6 manager with engine-backup, successfully restored it to a new CenTOS7 running 4.0, and trying to run ovirt-engine-rename. It always fails, and I am not sure where to look: /usr/share/ovirt-engine/setup/bin/ovirt-engine-rename [ INFO ] Stage: Initializing Welcome to the ovirt-engine-rename utility More details about the operation and possible implications of running this utility can be found here: http://www.ovirt.org/Changing_Engine_Hostname [ INFO ] Stage: Environment setup Configuration files: ['/etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf', '/etc/ovirt-engine-setup.conf.d/10-packaging.conf', '/etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf'] Log file: /var/log/ovirt-engine/setup/ovirt-engine-rename-20170127124705-a1y8is.log Version: otopi-1.5.2 (otopi-1.5.2-1.el7.centos) [ INFO ] Stage: Environment packages setup [ INFO ] Stage: Programs detection [ INFO ] Stage: Environment setup [ INFO ] Stage: Environment customization New fully qualified server name: []: newname.domain.com --== PRODUCT OPTIONS ==-- [ INFO ] Stage: Setup validation [ INFO ] Engine machine hosting Storage Domains The following Storage Domains use the engine machine as an NFS server: ISO_DOMAIN They will be modified to use the new name.

I do use custom Apache certificates. CA files are restored fine from backup. Where can I start looking next? Thank you!

Translate hint
by Gianluca Cecchi 27 Jan '17

27 Jan '17

Hello, I'm checking Italian Translation in 4.0.6 and completing it for 4.1 (now at 92%). Suppose I found an untranslated / bad translated word: what is the best and quick way to go to Zanata and find the reference for it and correct? For example in 4.0.6 I'm in dashboard and at bottom I have the three labels Alert, Events, Tasks I click ALerts and then I want to dismiss an Alert because it happened while I was configuring Power Management: I faked the password to verify that the test failed and I got the alert Power Management test failed for Host ..... I rght click on the alert line and I see three options and the first and third one are untranslated they are Dismiss Alert Display All (I'm going to send a separate e-mail to ask about alerts and events in general). If I go to Zanata, select oVirt 4.0 and Italian language line and use the search function I don't find anything.... I see there is an option to Download All for Offline Translation and Export Italian Documents to TMX I have not tried them yet, but I would prefer to directly correct online while I find some things to correct.

Migrate hosted engine to a new storage domain
by Logan Kuhn 27 Jan '17

27 Jan '17

Hi We are planning on moving to a different storage solution and I'm curious, is there a way to migrate the hosted engine's storage domain to the new solution? It's NFS currently and can be NFS on the new storage as well. >From what I've read it looks like it should be possible to 1. Take a full backup of the engine VM 2. Deploy another hosted engine VM with hosted-engine --deploy 3. Install/configure CentOS 7.3 4. Deploy new engine with engine-setup 5. Then restore the backup into the new VM. What I'm not sure of is if that backup will contain enough of it's data to restore to a completely different storage domain? Also, the engine database is on a remote server, the data warehouse service and all other aspects of the hosted engine reside on the VM. Thanks, Logan

Distribute collection of VMs
by Fredrik Olofsson 27 Jan '17

27 Jan '17

We currently use an OVA-file for Virtualbox to distribute a collection of VMs to our customers. We would like to also support customers using oVirt. Our VMs work if we convert the disk images to qcow2 and manually configure the VMs. Specifically the network interface connections needs to be configured. Is it possible to automatically import the OVA file (from the many threads here I guess not..)? What is the preferred method to distribute a collection of VMs for use in oVirt? Best regards /Fredrik Olofsson
