Martin, do you have any updates? please note that ovirt-engine has been broken for a few days so perhaps we should stop merging or revert the original change?

​Still looking at it, here are partial results:

1. New host installation: never reproduced, 4.2 host is always installed fine on 4.2 engine

2. Upgrade - never reproduced, upgrade of both 4.1 engine and host to 4.2 was always successfull

3. Reinstallation - once it happened to me that during reinstallation the host remain stucked during Reinstallation and the whole​ reinstallation failed due to timeout

    - that may be the issue which can be seen in CI, but so far I don't have reliable reproducer to be able to debug why host-deploy process on the host is stucked

Did you try using OST locally? it reproduces consistently with the OST upgrade suit. You can also use the manual job and pass a URL to any engine build beyond the marked patch. But there you'll have the same issue as with the CQ job where you won't have logs...

Note, the process that happens there is AFAIK:

1. The oVirt 4.1 release is installed.

2. engine-setup runs

3. repos are changed to the master repo

4. engine is upgraded

5. bootstrap (including AddHost that fails is carried out)

Looks like the same issue:
