the permissions on /dev/kvm seem to get reset every so often somehow :/ I'm not sure if this is infra rebooting the machine and not telling me, or something else.
I have set up a service which is supposed to run on boot and change the permissions, but it seems like possibly it's not working right :/
did you rebooted the Power8 machine and forget to enable /dev/kvm to all users ? (and set smt=off)
seems to be the case since three last Builds:
The reported failure about "bootloader install failed" found in f27 branch 20170818
is now also on Rawhide-20170822, new brc#1484474 created by Adam Williamson
Rawhide compose 20170830: above problem solved, but script error like https://openqa.stg.fedoraproject.org/tests/152417/file/autoinst-log.txt
