I would personally put CloudStack in the same category as OpenStack.
Really the only difference is monolithic vs micro services. Both scale
quite well regardless, just different designs. People can weigh the pros
and cons of either to figure out what suites them. CloudStack is
certainly an easier thing to wrap your head around initially.
There is also OpenNebula, similar to CloudStack in design. However their
upgrade tool is closed source, so i can't recommend them as much as i
would like to as i think they have a decent product otherwise.
ProxMox currently doesn't work as an oVirt replacement for us as it
cannot scale beyond a single cluster and has limited multi tenancy
support. I hear they have plans for multi cluster at some point, but
currently i regard it as more akin to ESXi without vSphere. Where oVirt
i would have compared closer to ESXi with vSphere.
I think XCP-ng has a bright future at the rate they are going, just
doesn't currently supply all the features of oVirt.
OKD (OpenShift) virtualization is more or less just kubevirt. If all you
need vm's for is a few server instances, works well enough. Feature wise
it's not comparable to everything above, but if you can live with your
vm's being treated more or less like containers workflow / life cycle
wise and don't need much more then that, it probably gets the job done.
Harvester is another consideration if you think the OKD solution will
work, but don't like the complexity. It's based on k3s, provides
kubevirt, and is a much more simple install. I think they even provide
an ISO installer.
Reality is, there is no great oVirt replacement so to speak. If you only
needed oVirt to manage a single cluster, ProxMox probably fits the bill.
XCP-ng as well if you are willing to do some leg work.
Otherwise closest FOSS thing i have found (spent over a year evaluating)
is CloudStack. I am still hopeful someone will step up to maintain oVirt
(Oracle?), but it's clear to me at this point it will need rebased onto
Fedora or something else to keep it's feature set fully alive.

Hi,
We switched from Gluster to NFS provided by SAN array: maybe it was
matter of combination of factors (configuration/version/whatever),
but it was unstable for us.
SPICE/QXL in RHEL 9: yeah, I understand that for some people it is
important (I saw that someone is doing some forks whatever)
I think that ovirt 4.5 (nightly build __) might be OK for some time,
but I think that alternatives are:
-OpenStack for larger setups (but be careful with distribution -as I
remember Red Hat abandons TripleO and introduces OpenShift stuff for
installation of OpenStack)
-ProxMox and CloudStack for all sizes.
-Maybe XCP-ng + (paid?) XenOrchestra, but I trust KVM/QEMU more than
Xen __
OpenShift Virtualization/OKD Virtualization - I don't know...
Actually might be good if someone specifically comments on going from
ovirt to OpenShift Virtualization/OKD Virtualization.
Not sure if this statement below
https://news.ycombinator.com/item?id=32832999 is still correct and
what exactly are the consequences of 'OpenShift Virtualization is just
to give a path/time to migrate to containers'
"The whole purpose behind OpenShift Virtualization is to aid in
organization modernization as a way to consolidate workloads onto a
single platform while giving app dev time to migrate their work to
containers and microservice based deployments."

We still have a few oVirt and RHV installs kicking around, but between
this and some core features we use being removed from el8/9 (gluster,
spice / qxl, and probably others soon at this rate) we've heavily been
shifting gears away from both Red Hat and oVirt. Not to mention the
recent drama...
In the past we toyed around with the idea of helping maintain oVirt,
but
with the list of things we'd need to support growing beyond oVirt and
into other bits as well, we aren't equipped to fight on multiple fronts
so to speak.
For the moment we've found a home with SUSE / Apache CloudStack, and
when el7 EOL's that's likely going to be our entire stack moving
forward.

I am beginning to have very similar thoughts. It's working fine for
me now, but at some point something big is going to break. I already
have VMWare running, and in fact, my two ESXi nodes have the exact
same hardware as my two KVM nodes. Would be simple to do, but I
really don't want to go just yet. At the same time, I don't want to
be the last person turning off the lights. Difficult times.
