Comment 17 for bug 1959014

Thanks, Gibi for your analysis, and Ronelle too (for the update in comment#16):

Meanwhile, two points:

(1) The original instance crash that Artom pointed out in comment#2 is not reproducible in later test runs. It seems tobe spurious

(2) The QEMU error: "unable to execute QEMU command 'blockdev-del'" was caused by a bug in libvirt, but that is NOT the root cause of the crash in point (1). This seems to be a latent bug in libvirt, uncovered by this test. And is being fixed upstream (by Peter Krempa):
