    deployment: libvirt: update machine type/model for all-in-one

    Refer also to commit 7abcd94a, which applies the change to
    controller.xml

    Tests should run on a comparably newer model of CPU and should be fixed
    for all tests under virtualization.

    Nehalem cpu model is recommended as one that has been used for this
    purpose for a few years.

    Specifying 'forbid' for fallback and 'exact' for mode will ensure that
    hosts the Qemu emulator is up-to-date on the host, capable of emulating
    the expect model. The consistency will make test results reliable
    across host machines.

    The newer machine type supports ACPI for example.

    The feature "vmx" is required on computes to support nesting.
