Guest OS field is set to Microsoft MS-DOS on Red Hat satellite 6.5

Solution Verified - Updated -


  • Red Hat Satellite 6.5


  • Guest OS field is set to Microsoft MS-DOS while importing RHEL8 vm from satellite 6.5 compute resource using vcenter.


  • This is a known issue filed in Bug 1713538 which is fixed in Satellite 6.6

  • Below is a workaround for satellite 6.5:

    # cd /opt/theforeman/tfm/root/usr/share/gems/gems/rbvmomi-1.10.0/
    # mv vmodl.db /tmp
    # wget
    # restorecon -Rv .
    # vi /usr/share/foreman/app/models/compute_resources/foreman/model/vmware.rb
    "rhel7_64Guest" => "Red Hat Enterprise Linux 7 (64-bit)",
    "rhel7Guest" => "Red Hat Enterprise Linux 7 (32-bit)",
    "rhel8_64Guest" => "Red Hat Enterprise Linux 8 (64-bit)",   =======> Add this line below the "rhel7Guest" parameter.
    # systemctl restart httpd
    # echo 'pp RbVmomi::VIM::VirtualMachineGuestOsIdentifier.values' | foreman-rake console | grep rhel8    =======> This should now show the RHEL8 Guest OS per VMware setting.

Root Cause

  • Guest OS version identifier not updated in satellite 6.5 and RHEL8 is supported in VMware version 6.7 and above.

  • Guest OS version identifier needs to be updated according to vmware documentation in satellite 6.5.
