[tck PATCH 1/4] storage: skip qcow1 tests when qcow1 isn't supported by qemu-img

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



RHEL8 has dropped support for qcow1 format images, so skip the tests
related to creating/cloning qcow1 images (based on the output of
qemu-img -help).
