Are you sure about this kernel version ? I can only get a kernel-5.1.0-0.rc1.git2.1.fc31 from rawhide - koji doesn't show any git2.2 build

I couldn't reproduce in the git2.1 build when trying to boot a plain guest via libvirt.
Comment 3 Daniel Berrangé 2019-03-25 12:38:49 UTC 
BTW, are there any AVCs from SELinux when this happens ?
Comment 4 Richard W.M. Jones 2019-03-25 12:52:30 UTC 
Thanks for looking at this.  This has now "fixed itself" after I upgraded everything to
Rawhide (ie. after dnf update --best) + a reboot, so I guess this is NOTABUG.

I'm going to close this but if it reoccurs in future will reopen with the additional
information you requested.
