Public bug reported: If a user places an OVA on Glance with its own storage independent of the VCenter, the import fails in nova with not finding the file in the vmware_temp directory.
I am using mitaka on a VCenter 6.0, but looking at the code, I would say it affects also liberty and later versions, when the Glance isn't storing the images directly in the VCenter (e.g Swift store) I created an OVA image in Glance (Swift backed), and then started a VM with the image. The import fails with a missing file. Essentially, the code is broken here: https://github.com/openstack/nova/blob/master/nova/virt/vmwareapi/vmops.py#L620-L629 `image_prepare` creates some temporary directory, which is never used in `image_fetch` aka `_fetch_image_as_ova`, and `image_cache` expects the imported image there. However, the function `_fetch_image_as_ova` imports the OVA as a VM, which places the root disk in a folder named as the imported image name. Attached is a patch, which makes the `_fetch_image_as_ova` function move the image to the cache directory, and changes the `image_prepare` and `image_cache` function to a noop. ** Affects: nova Importance: Undecided Status: New ** Patch added: "0001-Fix-import-of-OVAs-with-VMwareVCDriver.patch" https://bugs.launchpad.net/bugs/1649232/+attachment/4790617/+files/0001-Fix-import-of-OVAs-with-VMwareVCDriver.patch -- You received this bug notification because you are a member of Yahoo!
