Host to guest mapping with Virt-who and fake hypervisor

Host to guest mapping not working on katello using virt-who and a fake hypervisor (AHV)

Expected outcome:
When sending to katello a fake virt-who mapping json file
I expect to assign licenses to my guests correctly.

The wirt-who log says: Hosts-to-guests mapping for config “fake-virt”: 1 hypervisors and 3 guests found
And the json file is uploaded correctly.

I can assign to my fake hypervisor a VDC license
but I cannot see my guests as part of the content host.

When I try to assign a license, on candelpin server (in debug mode) I can see:
WARN org.candlepin.bind.PreEntitlementRulesCheckOp - Entitlement not granted: [] for pool: 8a84becb68cd8f140168dc73f91e04cc
ERROR org.candlepin.bind.BindChain - Skipped chain in preprocess of operation PreEntitlementRulesCheckOp

And on client side I see:
Pool “8a84becb68cd8f140168dc73f91e04cc” is restricted to guests running on host: “0ea35d1d-3f34-450f-9289-47bfb9193519”

this is just a wild guess based on my experience with virt-who.
The env setting seems off to me. I would expect something like Library/Content_View.
On your virt-who host, could you run subscription-manager identity and update the env field wih the content of the environment_name from that output.

Thanks for the quick answer. I double checked that setting.
My output for subscription-manager identity env name is correct:

environment name: Library

Is there a way to query candlepin asking for “current host to guest map” ?

I’m quite sure there is some way to do that, but none that I am aware of.
Maybe someone with better knowledge if the inner workings with candlepin can help, but if the config is correct, I’m out of ideas.

please confirm that those are system uuids for the guests and not consumer uuids.

I used the wrong uuids in fake wirt-who maping.
When you send your JSON data you have to be sure to NOT use “foreman uuids” assigned to machines
but the real ones from:

# subscription-manager facts | grep virt.uuid
