Thank you Artur, it make sense. oVirt itself recommend a small set of supported browsers. I will try this approach on building the ovirt-engine rpm package.

It will literally eat all the memory that is available :/. If you need it for development purposes then you can use "ovirt_build_minimal 1" make the build much faster and not that memory hungry: $ rm ovirt-engine-*_master.tar.gz ; make clean && make dist && time rpmbuild -D"ovirt_build_minimal 1" -tb ovirt-engine-*_master.tar.gz If you want more user agents supported you can define them as [1]: -D"ovirt_build_user_agent <comma separated list of user agents>" [1] https://github.com/oVirt/ovirt-engine/blob/master/README.adoc<https://... I hope that helps.

When I run a rpmbuild -ba ovirt-engine.spec, it fails with the following error: [ERROR] Out of memory; to increase the amount of memory Also, it indicates the option -Xmx8192M in the pom.xml file. The weird part is that building the application in the command line works fine but not in the rpmbuild, neither using a mock build system. I checked this page https://github.com/oVirt/ovirt-engine<https://urldefense.com/v3/__http... from GitHub and tested those variables with no success. Can anyone point me where I can find how to use those variables when building the package or have experience building this package/application to explain it? Thank you in advance for any help.
