Aka Servidéo 3.0
-
1 host
-
many virtual machines to host:
-
RHOCP
-
RHEL 8 (if not in RHOCP CNV)
-
As stated in the Chapter 20. Feature support and limitations in RHEL 8 virtualization Red Hat Enterprise Linux 8 from the Red Hat Customer Portal, only 4 VMs are supported at the same time on a RHEL 8 and also some virtualization features are not supported neither. Most of them are supported with RHV and others via RHOSP. KVM binaries are now the same in RHV and RHEL and RHOSP.
(un)fortunately, hosting RHOCP on VMs is not a supported setup. And all the features are available even if not supported. And everything will be managed with ansible.
Then, why bothering with another management VM (RHV-M) consuming resources.
Conclusion: Native KVM.
