ARMv7l packages seems not be building

Dear people,

During this weekend I watched the build progress of my ARMv7l repository, because i changed a few packages/source. But it seems that none of the packages are really being build. They all stay on the “scheduled” state, sometimes one or two goes to the “build” state, but after like 10-30 seconds it shifts back to “scheduled” again. Almost none of the packages stays in the build state long enough to even get a view at the build log. I already tried wiping the existing binaries, force rebuild, removing all referenced projects except the openSUSE:13.2 (repository: ports). But it does not make any difference.
By taking a closer look to the build status monitor page it seems none of the packages listed as being build on the ARMv7 hosts are being build. I was able to catch the build log from one of my packages once, by using the command line tool osc. It seems like it can not start the VM due to a wrong kernel image. Below is the log I was able to catch, after those 20 seconds the package turned back to the “scheduled” state again.
I did not see any message about build problems or ARMv7 specific things on the front-page, mailing list or on this forum. All other architectures seems to build fine, but I did not check it that closely.

Hopefully someone can look into this.

Everyone thanks in advance.

Btw. everybody who makes this great service possible, big thanks.

Do not know if anything changed, but since a few days everything is functioning properly again. Guess it was a false alarm.
