Re: F24 QEMU running away at 100% cpu after system resume

There's a bug about this issue with that's lingered in a lot of forms for a while:

https://bugzilla.redhat.com/show_bug.cgi?id=1380893

But with my testing, kernel > 4.9 inside the VM fixes the issue. So supported
fedora releases in the VM aren't affected anymore. You can work around it by
disabling kvmclock for the VM, but I'm not sure what other side effects that
will have
