Guests of Hypervisor link not showing for guest subscriptions
Setup VDC subscription w/ hypervisor and register a guest
Check Subscriptions page and notice there is no "Guests of" link
Fixes #21660 - Subscription's "guests of" link
The "guests of <hypervisor>" link was broken because
we changed the subscription API to no longer return hosts.
This commit will grab the "requires_host" value from
candlepin and adds that to a new field on the pools table,
"hypervisor_id". This can then be referenced by UI, which
will display the associated hypervisor.
To test you will need to register a VDC subscription and a
hypervisor running virt-who w/ guests.
