is it data or iso storage domain you're using? I observed same behavior on data domain, but on iso it worked for me.
we've changed the default selection of "Enable incremental backup" so now it's selected by default but yeah, in upload-image it leads to this awkward situation in which an ISO changes to QCOW. we need to make sure that for ISOs we disable the "Enable incremental backup" option and create them as RAW disks as a workaround, the "Enable incremental backup" can be unchecked until then
This bug report has Keywords: Regression or TestBlocker. Since no regressions or test blockers are allowed between releases, it is also being identified as a blocker for this release. Please resolve ASAP.
(a consequence of the fix for bz 1915029)
Verified. VM successfully ran from the uploaded ISO. "Enable Incremental Backup" option is not available for ISO anymore. Versions: engine-4.5.3-0.1.el8ev
