oVirt backup and VM pauses.
by Misak Khachatryan 09 Mar '17

09 Mar '17

Hello, I'm using oVirt and recently added backup functionality using this script: https://github.com/wefixit-AT/oVirtBackup This script runs every day from cron, but i noticed very bad behavior with the machines. Script on some stage pauses them, and it leads to problems. I have NTP stratum 2 server as a virtual machine, which I added to pool.ntp.org. When machine pauses, it loses time sync for a while and NTP.ORG monitoring system removes this machine from pool. And it take about a 24 hours to get good score to be included int the pool again, then next backup time arrives, and so on. So my question is - any suggestion to prevent this behavior or any other backup solution without pausing available? Best regards, Misak Khachatryan

Shrink gluster logical volume under Ovirt 4.0
by Ian Neilsen 09 Mar '17

09 Mar '17

Hi all I need to shrink/reduce the size of a gluster logical volume under Ovirt 4.0. Is there anything I should be aware of before reducing the file system and logical volume on my servers? I ask because I see under "df -h" the following; 192.168.3.10:data 5.7T 3.4G 5.7T 1% /rhev/data-center/mnt/glusterSD/192.168.3.10:data The storage domain is not connected yet via oVirt manager, well at least it isnt showing. Im running in hosted mode converged. Thanks in advance -- Ian Neilsen Mobile: 0424 379 762 Linkedin: http://au.linkedin.com/in/ianneilsen Twitter : ineilsen

ovirt_nics problem at ansible module

Hi, Below is my playbook --- - name: Setup oVirt environment hosts: vms tasks: - block: - name: Include oVirt password #no_log: true include_vars: vars.yml - name: Obtain SSO token no_log: true ovirt_auth: url: "{{ url }}" username: "{{ username }}" password: "{{ password }}" ca_file: "{{ ca_file }}" - name: Create and run VM from template ovirt_vms: auth: "{{ ovirt_auth }}" name: "{{ vm }}" template: "{{ template }}" cluster: "{{ cluster }}" memory: "{{ memory }}" memory_guaranteed: "{{ memory_guaranteed }}" high_availability: true cpu_cores: "{{ cpu_cores }}" cpu_sockets: "{{ cpu_sockets }}" type: server name: "{{ vm }}" operating_system: other_linux state: stopped wait: yes #- name: Add nic # ovirt_nics: # auth: "{{ ovirt_auth }}" # name: "{{ nic_name }}" # profile: "{{ profile_name }}" # state: plugged # vm: "{{ vm }}" # wait: yes always: - name: Revoke the SSO token ovirt_auth: state: absent ovirt_auth: "{{ ovirt_auth }}" When i remove the commented lines here is what i got: ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path. The error appears to have been in '/Users/oyarimtepe/test/ovirt-ansible/create_vm_from_template/playbook.yml': line 35, column 11, but may be elsewhere in the file depending on the exact syntax problem. The offending line appears to be: - name: Add nic ^ here The error appears to have been in '/Users/oyarimtepe/test/ovirt-ansible/create_vm_from_template/playbook.yml': line 35, column 11, but may be elsewhere in the file depending on the exact syntax problem. The offending line appears to be: - name: Add nic ^ here I tried using the nics attribute of ovirt_vms module but this time i got Nic[Name] is required although i defined as below: nics: - name: "{{ nic_name }}" - profile_name: "{{ profile_name }}" without comments it works. Any idea? Any way to set the nic and profile via SDK? An example will be great. -- Oğuz Yarımtepe http://about.me/oguzy

Graphics are turned upside down when install QXL in Windows
by Karli Sjöberg 08 Mar '17

08 Mar '17

Heya! Just thought that I´d report something hilarious:) After installing the QXL driver in Windows 7 and 2008R2, in the SPICE HTML5 browser client, all of the graphics are turned 180 degrees. It´s not that the entire screen is flipped either, but all of the individual elements are. E.g. the trashcan that should be in the top right corner is now located in the bottom right, flipped upside down with the text "above" it and text also flipped. Opening an explorer windows still has the location and search bar at the top, with location bar first and search bar to the right, as it should be, but with the graphics turned upside down, plus that the text is still printed from left to right, but upside down. And the "favorites" pane is still located to the left but listed from bottom the top, Windows has never looked this funny:) A picture says a thousand words. Behold! http://imgur.com/a/32P12 The native client displays as it should. Just letting you know. /K

oVirt Nodes Monitoring
by FERNANDO FREDIANI 08 Mar '17

08 Mar '17

Hi. How do you guys monitor your hosts with Zabbix ? I see the oVirt Nodes have snmpd service installed and could be used for basic things but ideally, for Zabbix is good to use its agent. What would be the best way to install its zabbix-agent package and make it persistent ? Add its repository to the oVirt-Node in /etc/yum.repos.d/ and install it with yum or install using a .rpm directly ? Thanks Fernando
