issue: virt.uuid should not be "Unknown" in s390x when list facts

Expected results:
virt.uuid should be a real uuid value instead of "Unknown"

Additional info:

Comment 1 Chris Duryee 2012-04-25 15:09:31 UTC
If virt.host_type is ibm_systemz, we explicitly mark the uuid as unknown. System Z VMs are not tracked via virt-who, so there is no need to track the virt.uuid.

Marking as closed/notabug, feel free to re-open the bz though if you have any questions or concerns.

Comment 2 John Sefler 2016-03-01 18:09:46 UTC
I agree that System Z VMs are not tracked via virt-who, but that's because we don't know how to do it yet.  The first step to figuring that out will be to determine the virt-uuid for this ibm_systemz-zvm.  Hence I am re-opening this bug as an RFE on s390x.

With the latest packages...
[root@ibm-z10-52 ~]# hostname
[root@ibm-z10-52 ~]# rpm -q subscription-manager virt-what
[root@ibm-z10-52 ~]# 
[root@ibm-z10-52 ~]# virt-what
[root@ibm-z10-52 ~]# 
[root@ibm-z10-52 ~]# subscription-manager facts --list | grep virt
lscpu.virtualization_type: full
virt.host_type: ibm_systemz, ibm_systemz-zvm
virt.is_guest: True
[root@ibm-z10-52 ~]# 

ISSUE: Since virt-what is indeed reporting this as a virtual guest, the subscription-manager facts should include a virt.uuid  Exactly how to determine the value of the virt.uuid is unknown.  For this we NEEDINFO.
