thank you Gianluca for the good link.
it was really helpful and, they are really different considering the notion.

but as "OpenStack" implements many features not only for cloud but also for traditional workload, I guess it's also good fit for traditional workload.
So, I'm wondering whether virtualization solutions like oVirt have meaningful strengths than OpenStack at this point in time.

Good that it was of help.

Like other pieces of software, I see in recent years that "adjacent" technologies tend to extend their capabilities to each other, compenetrating ...

For example latest virtualization features of Openshift:

https://www.redhat.com/files/summit/session-assets/2019/T47177.pdf

and then these new VMs created in Openshift that should also be manageable from oVirt 4.4...

Or OpenStack components landing in oVirt, like cinderlib and Open vSwitch

In my opinion some basic reasons to use oVirt for virtualization instead of OpenStack:

- if the main need is compute, because network and storage are already provided externally (while OpenStack as IAAS provides the whole "Infrastructure" as a server of the capital "I")

- if there are already settled departments for network and storage, so that who manages VMs is not in charge of the other infrastructure components and with oVirt you easily keep segregation of duties/responsibilities

- small environments in terms of compute nodes (2-3 but also something like 10)

- very very easier upgrades through minor and major releases

HIH,
