HI Gianluca, I have had a look at the change and it's a single line of code added on the hosted-engine. I'll verify that it's working 4.3 and will make a note of checking it with engine upgrade, which for now seems the less troublesome approach. Hopefully it will get integrated/backported also

Dear Nir, I am sorry if that sounded too harsh. I do appreciate what you are doing! The thing is, that my only chances at getting my employer to go with the commercial variant depend a lot on the upstream project showing already demonstratable usability in the research lab. Just try to imagin

Nir, first of all, thanks a lot for the detailed description and the quick fix in 4.4! I guess I'll be able to paste that single line fix into the 4.3. variant myself, but I'd rather see that included in the next 4.3 release, too: How would that work? --- "OVA is not a backup solution": From

Keep in mind that oVirt relies on OS components like qemu and if they do fail it is not oVirt's fault. Also, OVA export/import is not the most popular approach for backup/restore in Virtualization Environments, so this bug should not be a reason to 'drop it like a hot potato' . Ye

Unfortunately that means OVA export/import doesn't seem to be a QA test case for oVirt releases... which would make me want to drop it like a hot potato, if there was any alternative at this point. I guess my biggest mistake was to assume that oVirt was like CentOS. _

Wow, it seems a good find for a potential reason! I'd totally subscribe to the cause, if it only affected my Atom HCI clusters, who have had timing issues so bad, even the initial 3 node HCI setup had to be run on a 5 GHz Kaby Lake to succeed, because my J5005 Atoms evidently were too slow. Bu
