Based on the data in this wiki

and discussions on the dev & operator mailing lists

We are able to increase the min required libvirt to 0.9.11

This will allow us to switch to using the (soon to be released) standalone libvirt python binding from PyPI, as well as removing some old compat code.

This bug should remain open as the minimum version in the libvirt driver itself has not yet been updated.

    Increase min required libvirt to 0.9.11

    Increase the min required libvirt version to 0.9.11 since
    we require that for libvirt-python from PyPI to build
    successfully. Kill off the legacy CPU model configuration
    and legacy OpenVSwitch setup code paths only required by
    libvirt < 0.9.11

        Increase min required libvirt to 0.9.11

    support for setting up OVS outside of libvirt was dropped,
    but 3 of the helper methods were mistakenly not deleted.
