Description Amar Huchchanavar 2017-05-01 08:57:43 UTC

Description of problem:
Virt-who could not read the guest-host mappings if 'hypervisor_id=hostname' and 'filter_host_uuids' are present in the configuration file.

'filter_host_uuids' is not compatible with 'hypervisor_id=hostname' option. We need to use 'filter_hosts=' to filter hosts.

Version-Release number of selected component (if applicable):
virt-who-0.17-11.el7_3.noarch

How reproducible:
Always

Steps to Reproduce:
1.Configure virt-who with below settings.
[howst-vcspv01]
type=esx
[all other details]
hypervisor_id=hostname
filter_host_uuids="446e2e7d-825a-5ca0-8cee-13ae9f56c903","4a9d7c0f-7058-4afd-8d06-42661872b48c","118f4087-7535-4187-8bc2-8e07fc676156"
2.Try to report the mappings.#virt-who -o -d


Actual results:
It fails to read the mappings,
~~~
017-04-21 15:07:53,606 [virtwho.main INFO] MainProcess(3074):MainThread @subscriptionmanager.py:hypervisorCheckIn:195 - Sending update in hosts-to-guests mapping for config "vcenter1": 0 hypervisors and 0 guests found
~~~

Expected results:
It should throw syntax error.

If  'hypervisor_id=hostname' option is present in the file, 
then force to use below two options:

filter_hosts="host1.example.com","host2.example.com","host3.example.com"  `OR`
exclude_hosts=host1.example.com,host2.example.com,host3.example.com

[filter_hosts - If provided, only hosts with hostnames in this list will be reported,
exclude_hosts - If provided, do not report hosts with hostnames in this list.]

Comment 2 Kevin Howell 2017-05-04 14:28:29 UTC

filter_hosts should work with hypervisor_id=hostname.

Comment 3 Kevin Howell 2017-05-04 14:29:11 UTC

we'll try to address as part of upcoming config linting changes
