Make the test script print following line when the test is finished and vmcore is successfully dumped:
You can retrive the verify the vmcore file using following command:
./scripts/copy-from-image.sh \
/home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/0-server.img \
/var/crash/192.168.77.62-2020-09-02-05:16:26/vmcore.flat ./
Kernel package verion is: kernel-core-5.6.6-300.fc32.x86_64
Also add a helper to copy files out of the VM image.

The Makefile In tests/ could help build a VM image using Fedora cloud
image as base image, or, user can specify a base image using
BASE_IMAGE=<path/to/file>. The current repo will be packeged and
installed in the image, so the image could be used as a test image to
test kexec-tools.
The image building is splited into two steps:
The first step, it either convert the base image to qcow2 or create
a snapshot on it, and install basic packages (dracut, grubby, ...)
and do basic setups (setup crashkernel=, disable selinux, ...).
See tests/scripts/build-scripts/base-image.sh for detail.
The second step, it creates a snapshot on top of the image produced by
the previous step, and install the packaged kexec-tools of current
repo. See tests/scripts/build-scripts/test-base-image.sh for detail.
In this way, if repo's content is changes, `make` will detect it and
only rebuild the second snapshot which speed up the rebuild by a lot.
The image will be located as tests/output/test-base-image, and in qcow2
format. And default user/password is set to root/fedora.
