Re: [libvirt] [PATCH 31/35] tests: qemublock: basic qcow2 tests

Add tests for backing chain handling, including a very long chain which is fully specified in the XML and an unterminated chain. The top level disk image would generate the following '-drive': file-qcow2-backing-chain-encryption.xml: -drive file=/var/lib/libvirt/images/a,encrypt.format=luks, encrypt.key-secret=node-b-f-encalias,format=qcow2,if=none,id=drive-dummy -device virtio-blk-pci,scsi=off,drive=drive-dummy,id=dummy file-qcow2-backing-chain-noopts.xml: -drive file=/var/lib/libvirt/images/rhel7.3.1507297895,format=qcow2,if=none,id=drive-dummy -device virtio-blk-pci,scsi=off,drive=drive-dummy,id=dummy file-qcow2-backing-chain-unterminated.xml: -drive file=/var/lib/libvirt/images/rhel7.3.1507297895,format=qcow2,if=none,id=drive-dummy -device virtio-blk-pci,scsi=off,drive=drive-dummy,id=dummy Signed-off-by: Peter Krempa <pkrempa(a)redhat.com&gt; --- tests/qemublocktest.c | 3 + .../file-qcow2-backing-chain-encryption.json | 34 ++++++ .../file-qcow2-backing-chain-encryption.xml | 31 +++++ .../xml2json/file-qcow2-backing-chain-noopts.json | 130 +++++++++++++++++++++ .../xml2json/file-qcow2-backing-chain-noopts.xml | 113 ++++++++++++++++++ .../file-qcow2-backing-chain-unterminated.json | 25 ++++ .../file-qcow2-backing-chain-unterminated.xml | 24 ++++ 7 files changed, 360 insertions(+) create mode 100644 tests/qemublocktestdata/xml2json/file-qcow2-backing-chain-encryption.json create mode 100644 tests/qemublocktestdata/xml2json/file-qcow2-backing-chain-encryption.xml create mode 100644 tests/qemublocktestdata/xml2json/file-qcow2-backing-chain-noopts.json create mode 100644 tests/qemublocktestdata/xml2json/file-qcow2-backing-chain-noopts.xml create mode 100644 tests/qemublocktestdata/xml2json/file-qcow2-backing-chain-unterminated.json create mode 100644 tests/qemublocktestdata/xml2json/file-qcow2-backing-chain-unterminated.xml
