Description:

def get_profiles(hypervisor=None, **kwargs):
    '''
    Return the virt profiles for hypervisor.

    Currently there are profiles for:

    - nic
    - disk

    :param hypervisor: override the default machine type.
    :param connection: libvirt connection URI, overriding defaults

        .. versionadded:: 2019.2.0
    :param username: username to connect with, overriding defaults

        .. versionadded:: 2019.2.0
    :param password: password to connect with, overriding defaults

        .. versionadded:: 2019.2.0

    CLI Example:

    .. code-block:: bash

        salt '*' virt.get_profiles
        salt '*' virt.get_profiles hypervisor=esxi
