Description Fabien Dupont 2020-03-27 13:35:37 UTC

Description of problem:

Currently, when we use two-phase migration, virt-v2v-wrapper transfers the disks data and then calls virt-v2v to actually convert the machine to KVM. During this conversion phase, an overlay is created to protect the virtual machine and virt-v2v-wrapper then commits this overlay.

To know the overlay file name, virt-v2v-wrapper watches virt-v2v log file. Unfortunately, the logging system wraps long lines and the file name may be on the line after the one that matches the regular expression. In this case, virt-v2v-wrapper fails because it cannot know the file name and finalize the migration.

Preliminary fix here: https://github.com/ManageIQ/manageiq-v2v-conversion_host/pull/41 but still needs testing before the PR can be merged.

Warm migration and UCI will finally not be implemented in CloudForms.
Closing as WONTFIX.
