Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description John Sefler 2021-08-04 12:17:00 UTC

Description of problem:

While testing this IBM POWER9 system reserved from Beaker (https://beaker.engineering.redhat.com/view/ibm-p9z-25-lp5.virt.pnr.lab.eng.rdu2.redhat.com#details), virt-what and the system facts indicate that the system is a virtual guest, but there is no virt.uuid fact due to the following WARNING found in the rhsm.log...

[WARNING] subscription-manager:84736:MainThread @virt.py:136 - Tried to read /proc/device-tree/vm,uuid but there was an error: [Errno 2] No such file or directory: '/proc/device-tree/vm,uuid'

I am not a ppc64le expert and I don't know how predictable this file is, but this system has the following file under /proc/device-tree/

[root@ibm-p9z-25-lp5 ~]# ls -l /proc/device-tree/ibm,partition-uuid
-r--r--r--. 1 root root 37 Aug  3 16:12 /proc/device-tree/ibm,partition-uuid

Actual results:

Expected results:
  Since virt-what reports this as a virtual guest and virt.is_guest is True, there should be a virt.uuid fact, but it is missing due to the WARNING.

Comment 1 Pino Toscano 2021-08-10 15:01:10 UTC

I just talked with Laurent Vivier, who works on KVM for POWER (thanks!).

https://openpowerfoundation.org/wp-content/uploads/2020/07/LoPAR-20200611.pdf

According to the POWER specs, in particular in B.5.2.1 (Root Node Properties), we have:

| “ibm,partition-uuid”
|
| property name specifies a universally unique identifier for this
| partition.
|
| prop-encoded-array: A string of data as described below,
| encoded as with encode-string
|
| The Universally Unique IDentifier (UUID) option provides each
| partition with a Universally Unique Identifier that is persisted
| by the platform across partition reboots, reconfigurations, OS
| reinstalls, partition migration, hibernation etc. The UUID is a
| 16 byte string of format fields and random bits as defined in
| Table B.4, “UUID Format” [813].
|
| The random bits are generated in an implementation-dependent
| manner to achieve a projected probability of collision of not
| greater than one in 2^60.

So yes, we can use /proc/device-tree/ibm,partition-uuid for the UUID of an LPAR system.
