For work reasons, I need a Fedora 28 VM.  I've got a bunch of disk space set aside to create logical volumes (LVM) for exactly this purpose, with several existing VMs.  On this occasion, I decided that I no longer needed an older Fedora VM and decided to recycle it.  I got the Fedora 28 x86_64 Workstation ISO image, set that as the boot CD in virt-manager, and fired it up.  I told it to install to disk and immediately ran into these (apparently duplicate bugs):

https://bugzilla.redhat.com/show_bug.cgi?id=1559686

Okay, so I zeroed out the partition table inside the logical volume and tried again.  The installer pegged the CPU at 100% and stayed there.  Okay, so maybe that LV is damaged beyond repair.  I created a new one out of the unused space in the VG and tried again.  Same result.  CPU pegged at 100%, installer completely unresponsive.

Does anybody have any tips on creating a VM with storage in an LV on a Fedora 28 host?  The above procedure worked just fine in F26 and F27, by the way.
