It's definitely python2 only at the moment. Upstream has #!/usr/bin/python, but the version in the RPM has #!/usr/bin/python3, maybe something in the spec changes it automatically? But I couldn't find anything. Can probably just change upstream to have explicit #!/usr/bin/python2 (or #!/usr/bin/env python2 and then overwrite that in the spec file) It's this Fedora patch: force-python3-in-kvm_stat.patch

Force python3 in kvm_stat
Right, so this is a fairly significant problem, and the short term solution will likely be kernel dropping kvm_stat for a bit until it works with python 3. I understand the reasoning behind moving it into the kernel tree, but Fedora's default python is python3 at this point. By putting a package which requires python2 in the kernel tools package, you end up with a lot of pissed off people who don't want python2 on their system. Ah interesting. It's probably not too hard to port to python3, I'll try and take a look. Another option could be to switch it to explicit python2 but not have an explicit python2 dep. Then anyone that wants to use kvm_stat will just have to manually install python2. I think that's probably fine in the short term since I don't think kvm_stat has many users, and python2 will be installed on a lot of systems anyways kernel-4.12.9-300.fc26 has been submitted as an update to Fedora 26. https://bodhi.fedoraproject.org/updates/FEDORA-2017-78c4c71539 kernel-4.12.9-200.fc25 has been submitted as an update to Fedora 25. https://bodhi.fedoraproject.org/updates/FEDORA-2017-4b4c022807 So the short term work around, I simply removed the dep, and the patch. This is technically incorrect packaging, but it seemed the better short term solution. Longer term, kvm_stat needs to be ported to support python3, and the dep needs to go back in. kernel-4.12.9-300.fc26 has been pushed to the Fedora 26 testing repository.

If problems still persist, please make note of it in this bug report. Fedora 28, same story: it doesn't work with Python 3, only with Python 2:
[ykaul@ykaul ovirt-system-tests]$ sudo kvm_stat
File "/usr/bin/kvm_stat", line 1137
def sortkey((_k, v)):
^
SyntaxError: invalid syntax
Switching to Python 2, all good (at least it seems to be running).
It's fixed upstream and in v4.17-rc1
