In the meanwhile, Wildfly 20 has been released: https://wildfly.org/news/2020/06/08/WildFly20-Final-Released/

There is an issue with infinispan cache configuration for dashboard on WildFly 20. But our current code works fine on WF 18/19.1 and EAP 7.2/7.3, so in 4.4.1 we will just bump WildFly to 19.1 and on later 4.4.z release we will try to get to WildFly 20.

Opened bug #1848872 for the rebase on Wildfly 20.

Hi Martin,

This is wrong, WildFly is used only on upstream oVirt, for downstream RHV we are using EAP. So the doc text should be:

With this release, the oVirt Engine runs on WildFly 19.1.0

This bugzilla is included in oVirt 4.4.1 release, published on July 8th 2020.

Since the problem described in this bug report should be resolved in oVirt 4.4.1 release, it has been closed with a resolution of CURRENT RELEASE.

If the solution does not work for you, please open a new bug report.
