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.
