Fixed patchsets according to Michael's comments and re-sending them.
The purpose of this patchsets is start work on superseding and removing
scripts under the kvm test scripts/ subdirectory, by turning them regular
parts of the kvm autotest framework.
Lucas Meneghel Rodrigues (5):
KVM test:
With check_image_foo = yes, KVM autotest will use
qemu-img to perform checks on the qcow2 image.
This new functionality intends to replace the
script check_image.py. The plan is to supersede most
of the pre/post scripts in place throughout KVM
autotest.
Changes from v1:
- We already only raise
With this we prepare to remove the aforementioned script.
Changes from v1:
* Accounting for the lost of the check_image_critical
logic, now just trap kvm_vm.VMError() exceptions and
log them as an error if they happen.
