The reason for this is that we aren't handling correctly the error in the code that detects API method signatures. This is strictly infra, not storage. Patch posted: https://gerrit.ovirt.org/#/c/83469/ Verified that attempt to download disk attached to a running VM fails with HTTP response code 404 instead of unexpected XML. This bugzilla is included in oVirt 4.2.0 release, published on Dec 20th 2017. Since the problem described in this bug report should be resolved in oVirt 4.2.0 release, published on Dec 20th 2017, it has been closed with a resolution of CURRENT RELEASE. If the solution does not work for you, please open a new bug report. |
