11:54 a.m.
The test checks that the newly introduced --block-driver option doesn't
break conversion. Basically its logic somewhat repeats test-v2v-i-disk.sh
and test-v2v-in-place.sh, but with the new option being set.
The checks it performs are:
1. Run disk-sourced conversion (-i disk) based on the phony windows.img
and check that it completes (i.e. produces converted disk and
corresponding domain XML;
2. Run libvirt-sourced in-place conversion based on an XML with virtio
vda disk specified (virtio-blk case) and check that the resulting
image has the phony viostor driver installed.
3. Run libvirt-sourced in-place conversion based on an XML with scsi
sda disk specified (virtio-scsi case) and check that the resulting
image has the phony vioscsi driver installed.
Note that the latter 2 cases aren't really comprehensive as v2v actually
copies all the drivers present in $VIRTIO_WIN, regardless of the block
driver specified. The real difference comes from the PCI ID values written
into the registry. But since we can't test real Windows and evaluate
those values, we're doing the best we can here, i.e. testing that conversion
doesn't break and drivers are still present with --block-driver option
being set explicitly.
