1. Using "file" command and I figured that the template from Marketplace is on QCOW v2, and I think that's what causing the magic block invalid. Using qemu-img to convert the template to compact=1.1(QCOW v3) solves the "image magic is incorrect" error.
2. However it introduces another error when using QCOW v3 to suspend/restore. libvirtd crashed with segfault when trying to "restore" for some reason. "checkpoint" is there however "checkpoint.xml" is empty. Therefore changing the "restore" in the KVM driver to NOT generate a XML solved the problem.
Please look into this issue.
