Hi, in OVirt 4.3 and earlier i had to activate many repositorys beside OVirt4.3 repo because of dependencies. centos-sclo-rh-release ovirt-4.3 ovirt-4.3-centos-gluster5 ovirt-4.3-centos-opstools ovirt-4.3-centos-ovirt43 ovirt-4.3-centos-qemu-ev ovirt-4.3-epel ovirt-4.3-virtio-win-latest in OVirt 4.4.4 documentation it is mentioned to enable only this 3 repos sudo subscription-manager repos --enable="rhel-8-for-x86_64-baseos-rpms" sudo subscription-manager repos --enable="rhel-8-for-x86_64-appstream-rpms" sudo subscription-manager repos --enable="ansible-2-for-rhel-8-x86_64-rpms" ovirt-release44.rpm installs ovirt-4.4 repo I don't want to run into any trouble when i start upgrading, so are that really all repos i need for OVirt 4.4.4?

On host level only IPoIB should work on CentOS 7 and on CentOS >= 8.4, RDMA is not supported.

I must have rebuilt that server a couple of years after the other ones. Nice hack! :-) Please note that you take a risk here. The cert includes the hostname, and now it's not matching the hostname that the client (the engine, in this case, or another host, e.g. for VM migration) expects. So if some piece of software checks this, it might fail. Personally, I wouldn't stay in this state for long. Best regards, -- Didi

I saw that yesterday! Thanks for the help guys. I'm not a Ruby programmer, so have been poking at this on and off for weeks. It looks like the two most recent PR's may have solved my two most apparent problems with the plugin. I want to test more functionality with vagrant (like suspend, halt, resume, etc), but 🤞we are fully on track again.
