Hi to all project maintainers, As you may know, over the last few months the oVirt project had got some code contributions geared towards enabling the use of s390x (Mainframe) machines as hypervisor hosts. As you may also know, if you've followed the relevant thread, some work had been done in collaboration with the Fedora community to enable os390x support in oVirt`s CI system. We're now at the point where we can take the final step and enable automated builds of node components for s390x/fc27. Looking at what we curently build for ppc64le, I already took the time and submitted patches to enable build jobs for vdsm [2], ovirt-host [3], and ioprocess [4]. The relevant maintainers should have had these patches land in thair inbpx already. Few questions remain however: 1. When would be the best time to merge the patches mentioned above? Given that some of the projects do not support fc27 yet, that the new build jobs may raise issues and that the 4.2 release is fast approaching, the right timing should be considered carefully.

2. Which additional projects need to be build? I can see we build some SDK components for ppc64le as wel, are those dependences of vdsm? Will we need to build then for s390x?

I wonder how come the last 4 don't have ppc64le builds.

The last 2 don't seem to even have proper build jobs. > For engine: AFAIK there is no intention to support running engine on anything other then x86_64 at this point. > This is only (some) the components that we build.

There is a full fedora build for s390x, so I suppose those are available there. Also, those are all mentioned in vdsm.spec right? So build-artifacts will not pass if they are missing right? -- Barak Korren RHV DevOps team , RHCE, RHCi Red Hat EMEA redhat.com | TRIED. TESTED. TRUSTED. | redhat.com/trusted

Should there be failures on s390x I would have a look.
