ASF GitHub Bot commented on CLOUDSTACK-10290: --------------------------------------------- rhtyd opened a new pull request #2651: CLOUDSTACK-10290: Introduce option to have config drives on primary storage URL: https://github.com/apache/cloudstack/pull/2651 This introduces a new global setting `vm.configdrive.primarypool.enabled` to toggle creation/hosting of config drive iso files on primary storage, the default will be `false` causing them to be hosted on secondary storage. The support is limited from hypervisor resource side and in current implementation limited to KVM. The next big change is that config drive is created at a temporary location by management server and shipped to either KVM or SSVM agent via cmd-answer pattern, the data of which is not logged in logs. This saves us from adding `genisoimage` dependency on cloudstack-agent pkg. The APIs to reset ssh public key, password and user-data (via update VM API) requires that VM should be shutdown. Therefore, in the refactoring I removed the case of updation of existing ISO. If there are objections I'll re-put the strategy to detach+attach new config iso as a way of updation. In the refactored implementation, the folder name is changed to lower-cased `configdrive`. And during VM start, migration or shutdown/removal if primary storage is enable for use, the KVM agent will handle cleanup tasks otherwise SSVM agent will handle them. ## Types of changes <!--- What types of changes does your code introduce?
