Comment 3 for bug 1959014

Interesting, it _looks_ like the instance crashed. I wonder if we can get the coredumps here.

We only see "blockdev-del" calls in the libvirt debug log. However, if a snapshot attempt _was_ really made, we should've also seen "blockdev-add" and "blockdev-snapshot-sync" calls. I'm wondering what's missing here. Perhaps we need more input from the libvirt/QEMU block layer devs

For context, check out the below related (resolved) bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1809409 — Failed to create volume from vm snapshot image

This was resolved via a libvirt fix in libvirt-6.0.0-17.el8 (https://bugzilla.redhat.com/show_bug.cgi?id=1820016). However the setup here is using libvirt-7.0.

Also, "blockdev-del" means, in QEMU language:

# @blockdev-del:
#
# Deletes a block device that has been added using blockdev-add.
# The command will fail if the node is attached to a device or is
# otherwise being used.
