Description Liushihui 2015-08-06 02:49:26 UTC

Description of problem:
When virt-who run at hyperV/vdsm/rhevm mode, it can't monitor host or guest's updating immediately. (eg: add/delete/migrate guest or add/delete host) 

Version-Release number of selected component (if applicable):
virt-who-0.14-2.el7.noarch
subscription-manager-1.15.6-1.el7.x86_64
python-rhsm-1.15.3-1.el7.x86_64
Satellite-6.1.0-RHEL-7-20150721.7

How reproducible:
Always

Steps to Reproduce:
1.Register system to satellite 
2.Configure virt-who run at hyperv/vdsm/rhevm mode, start virt-who service
[root@hp-bl495cg5-02 ~]# cat /etc/sysconfig/virt-who  | grep -v ^# | grep -v ^$
VIRTWHO_BACKGROUND=1
VIRTWHO_DEBUG=1
VIRTWHO_VDSM=1
[NOTE]: We hasn't configure refresh interval #VIRTWHO_INTERVAL=0
3.Add/delete/migrate guest, monitor host/guest mapping info in the virt-who log

Actual results:
Virt-who can't monitor the guest's info's updating until 1 hour later

Expected results:
Virt-who should listen to vdsm/hyperv events

Additional info:

Comment 1 Radek Novacek 2015-08-18 11:48:56 UTC

There are no events (as far as I know) that virt-who can listen to. virt-who has to poll for changes. This applies to all of hyperv/vdsm/rhevm. If there are events that virt-who can use for monitoring, please let me know.

I'm sorry, I have to close this as CAN'T FIX.
