it passed without problems. Did you say this was a reliable
reproducer on your system?

This was run on a Debian testing system, with kvm version:
QEMU emulator version 4.2.0 (Debian 1:4.2-3)
What about hardware details of your system? How many CPU's, memory,
etc.? And what sort of storage device are you using for kvm? (I'm
using virtio-scsi backed by LVM volumes for the scratch and test
partitions.)
