After recent updates in f33 i've got this error when trying to edit CPU section:

  Error refreshing hardware page: attrib must be dict, not NoneType


Traceback (most recent call last):

    if not self._cpu_secure_is_available():

  File "/usr/share/virt-manager/virtinst/domcapabilities.py", line 267, in _convert_mode_to_cpu
    root.attrib = None
TypeError: attrib must be dict, not NoneType
