    oVirt is **one** alternative to vSphere 😉 For Xen world, there is Xen Orchestra, which is also Open Source. See ‘https://xen-orchestra.com’

    Click “continue” choose “Adminstrator Portal” it loop to alert message

    How can i do to resolve?
    Please help

    Thanks

  5. Try to access the oVirt Portal using FQDN(Fully Qualified Domain Name) instead of IP address , In case DNS entry is not configured update your system’s hosts file put below entry so that it can resolve FQDN into your oVirt Engine Server’s IP address.

    FQDN

    i install on centos the ovirt and i got error, after i follow the steps when i want access the administrator :
    The client is not authorized to request an authorization. It’s required to access the system using FQDN.
    ‘https://80.1.123.15/ovirt-engine/error.html’
    80.1.123.15 its a example on the link
    i read on here the solution is edit the hosts in /etc/hosts , so i write in ssh console :
    nano /etc/hosts
    and i have this:

    127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

    How i resolve the problem what to add, maybe someone can help the novices.
    thank you a lot

    • Hello Sage,

      Set the FQDN on your server with the command “hostnamectl set-hostname fqdn” and update your server’s host file as well, add the entry like below :

      ip_address_of_server FQDN

      Also add the same above entry in your machine from which you are trying access ovirt portal. Hope these steps will resolve the issue.

      Same issue, not sure is it a common issue or…. Running on the vmware vm.

    • Nikel says:

      For those who tried on vmware or virtualbox:

      On Windows host:

      Install xming server from: https://sourceforge.net/projects/xming/
      Install Putty and access the server via ssh (enable x11 before opening session)

      On Server guest:

      yum install xorg-x11-xauth xterm
      vi /etc/ssh/sshd_config/

      X11Forwarding yes

      yum install firefox

      firefox

      Now you should be able to access web console.

    • Stefano Stagnaro says:

      You can specify an alternative FQDN simply by editing the SSO_ALTERNATE_ENGINE_FQDNS variable in /etc/ovirt-engine/engine.conf.d/11-setup-sso.conf on the oVirt Engine.

      Then restart the engine daemon:
      # systemctl restart ovirt-engine.service
