Bug 1246951

I don't think this issue is valid. virt-who behaves differently for remote libvirt connection, it behaves like with ESX and reports remote host with its guests using hypervisorCheckIn API call.

For local libvirt connection, the subscription-manager sends the hostname. For remote libvirt connection, virt-who gets the hostname from libvirt. This might cause different behaviour.

I don't see this as a bug, one host should be monitored using both local and remote libvirt mode. Do you agree?

Radek,I agree with you.However,remote libvirt mode hasn't support reporting hostname. Therefore, I use this bug to track "support for hypervisor_id to the remote libvirt mode", is that acceptable? Thanks.

Yes, I'll add support for hypervisor_id to the remote libvirt backend.

Fixed in virt-who-0.14-3.el7.

Verified it on virt-who-0.14-3.el7.noarch since virt-who can report hostname after configure "hypervisor_id=hostname" when it run at remote libvirtd mode

Verified version
virt-who-0.14-3.el7.noarch
subscription-manager-1.15.9-2.el7.x86_64
python-rhsm-1.15.4-2.el7.x86_64
Satellite 6.1.0-20150731.0

Verified process:
1. Register system to Satellite server
[root@hp-z220-08 ~]# subscription-manager register --username=admin --password=admin
2. Configure virt-who run at remote libvirt mode, and configure send hostname instead of hostuuid
[root@hp-z220-08 ~]# cat /etc/virt-who.d/virt 
[test-libvirt]
type=libvirt
server=qemu+ssh://10.66.144.5/system
username=root
password=qwer1234P!
owner=ACME_Corporation
env=Library 
hypervisor_id=hostname
3. Restart virt-who service and check host/guest mapping info
[root@hp-z220-08 ~]# systemctl restart virt-who
[root@hp-z220-08 ~]# tail -f /var/log/rhsm/rhsm.log

}
4. Open satellite web UI, check content host

Result:
virt-who send hostname instead of hostuuid to satellite, hostname can shown on the satellite web UI. Therefore, verify it
