The root cause of this issue should be fixed with blivet-2.1.6-1 (latest compose has 2.1.5-1); specifically, this commit https://github.com/rhinstaller/blivet/commit/417e08b882d25c34a88c51aae4ae190359797fbe which was part of the fix for bug 1379865.

I'll set this to ON_QA for now since that updated package is available in bodhi. Jan, once a new s390x compose is done containing this new blivet, please retest to verify this now works.

Because blivet-2.1.6-1 is part of the last push to stable, the updated build will be present in today's compose.
Comment 4 Dan Horák 2016-10-11 10:04:42 UTC 
The issue seems to be still here with the F-25 Beta RC from http://s390.koji.fedoraproject.org/compose/25/Fedora-25-20161007.0/compose/Server/s390x/ (and python-blivet-2.1.6-1.fc25 is included in the repos)

Ok, whoops. Turns out this was very simple to fix. And in anaconda.

I can confirm the proposed patch fixes this issue. I've used updates=http://junkyard.lab.eng.bos.redhat.com/f25/s390x/updates-1378338.img
Comment 7 Sinny Kumari 2016-10-13 07:18:44 UTC 
I also tried with:
updates=http://fedora.danny.cz/s390/updates-1378338.img

as mentioned by Dan on Mailing List https://lists.fedoraproject.org/archives/list/s390x@lists.fedoraproject.org/thread/3X2IQAWJ464T7NRAB4N5JJJXWO7PLJKF/

Latest s390x nightly compose (Fedora-25-20161012.n.0) installs fine with vnc.
Comment 8 Samantha N. Bueno 2016-10-13 18:58:31 UTC 
Thanks everybody for testing. And thanks to Dan for creating an updates.img (apologies for not making one myself).

This will be in the next version of anaconda, which I'm building right now.
