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.

Fixed In Version: libguestfs-1.20.11-7.el6
Doc Type: Bug Fix
Doc Text:
Cause: gdisk was not available as dependency for libguestfs. Consequence: The gdisk feature was not available, and thus the two APIs guestfs_part_get_gpt_type and guestfs_part_set_gpt_type were not usable. Fix: Add gdisk as dependency. Result: The gdisk feature is available, and the two APIs guestfs_part_get_gpt_type and guestfs_part_set_gpt_type are usable.

Description Richard W.M. Jones 2013-05-21 10:05:58 UTC 
Description of problem:

libguestfs is being rebased in RHEL 6.5 (bug 958183) in order
to support the new version of virt-v2v (bug ?).  As well as
the rebase, some newer APIs will have to be backported.  It
appears only these are required:

 guestfs_part_get_gpt_type (added in 1.21.1)
 guestfs_part_set_gpt_type (added in 1.21.1)

Matt: Please add any further APIs to this bug.

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

libguestfs 1.20.6

><fs> help part-get-gpt-type 
NAME
    part-get-gpt-type - get the type GUID of a GPT partition

SYNOPSIS
     part-get-gpt-type device partnum

DESCRIPTION
    Return the type GUID of numbered GPT partition "partnum". For MBR
    partitions, return an appropriate GUID corresponding to the MBR type.
    Behaviour is undefined for other partition types.

><fs> help part-set-gpt-type
NAME
    part-set-gpt-type - set the type GUID of a GPT partition

SYNOPSIS
     part-set-gpt-type device partnum guid

DESCRIPTION
    Set the type GUID of numbered GPT partition "partnum" to "guid". Return
    an error if the partition table of "device" isn't GPT, or if "guid" is
    not a valid GUID.

    See
    <http://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_type_GUIDs>
    for a useful list of type GUIDs.

New APIS add, and work, so change the status to verified
Comment 10 Richard W.M. Jones 2013-10-01 13:17:25 UTC 
I'm afraid comment 9 doesn't count as verification.  tzheng
discovered (bug 1012805) that although the APIs exist, they
don't work because gdisk isn't included in RHEL 6.5.

It's fairly easy to demonstrate this:

$ guestfish -N part:1G:gpt part-get-gpt-type /dev/sda 1
libguestfs: error: part_get_gpt_type: feature 'gdisk' is not available in this
build of libguestfs.  Read 'AVAILABILITY' in the guestfs(3) man page for
how to check for the availability of features.

or:

$ guestfish -N part:1G:gpt part-set-gpt-type /dev/sda 1 0FC63DAF-8483-4772-8E79-3D69D8477DE4
libguestfs: error: part_set_gpt_type: feature 'gdisk' is not available in this
build of libguestfs.  Read 'AVAILABILITY' in the guestfs(3) man page for
how to check for the availability of features.
Comment 11 Richard W.M. Jones 2013-10-04 17:41:08 UTC 
We decided (sensibly IMHO) to push this bug out to 6.6.
Comment 12 Richard W.M. Jones 2013-10-04 17:42:44 UTC 
BTW I'm setting QA flag back to ? because I believe the QA
test for this to be wrong.  See comment 10.

Verified with libguestfs-1.20.11-8.el6.x86_64

# guestfish -N fs part-disk /dev/sda gpt : part-get-gpt-type /dev/sda 1 : part-set-gpt-type /dev/sda 1 EBD0A0A2-B9E5-4433-87C0-68B6B72699C0 : part-get-gpt-type /dev/sda 1

The API works.
