Hello,
Though I read some surveys about this, I'd rather directly ask the oVirt
community this question, and especially to people using it as a
production cluster : as an average, how many VM are running on each of
your hosts?

The host with 1TB RAM or 64GB?
There is no meaningful average for two reasons :
- Host specs (example above) - some believe in scale up (fewer but stronger
hosts), some believe in scale out (more hosts, not as high end).
- Workload specs - Virtual desktop VMs with 2-8GB of RAM, or large
in-memory 512GB 'monster VMs'?
We see both. So it can range from very few to hundreds.

*This* is mainly the point I am expecting to get some stats.
Literature about competitor's products are commonly describing few and
strong hosts scenario, but I'd like to know how it goes in oVirt's world

We've got around 100VMs with 175vCPUs running on 48pCPUs spread over 4
hosts. At the moment the storage layer is the limiting factor. VMs are a
mix of postgres database servers wildfly application servers with
geoserver and then some assorted infrastructure stuff and a couple of
Windows servers.
