Description Liushihui 2017-01-20 06:56:49 UTC
Description of problem:
When virt-who work at xen mode, configure hypervisor_id=hostname/hwuuid can't work, virt-who hasn't send hostname and hwuuid but send uuid to satellite.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Configure virt-who run xen mode and send hostname to satellite.
[root@hp-z220-08 virt-who.d]# cat /etc/virt-who.d/virt 

2. Check xen host's hostname
[root@master ~]# hostname

3. Restart virt-who and check virt-who's log.
[root@hp-z220-08 virt-who.d]# service virt-who restart && tail -f /var/log/rhsm/rhsm.log

Actual results:
Virt-who still send uuid other than hostname to satellite although it has configured hypervisor_id=hostname

Expected results:
hypervisor_id should take effect. 
1. when set hypervisor_id=hostname, virt-who should send hostname to server
2. when set hypervisor_id=hwuuid, virt-who should send hwuuid to server

Additional info:
It hasn't this problem when virt-who run at esx/rhevm mode.

Comment 4 Chris Snyder 2017-05-12 19:15:11 UTC
Has this feature ever worked with xen mode?

If not I think we should classify this bug as an RFE (as it would be net new functionality).

Comment 6 Chris Snyder 2017-06-07 20:12:41 UTC
After investigation it appears current virt-who is able to differentiate between the different hypervisor_id settings when run in xen mode.


When I used the reproduction system provided in Bug 1401420, I see that both the xenmaster and xenhost systems appear to have the same hwuuid.

As this behaviour is not a regression I will move the bug to 7.5.
