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.

Red Hat Product Errata RHBA-2011:1512 0 normal SHIPPED_LIVE libguestfs bug fix update 2011-12-06 00:39:11 UTC

Description Erez Shinan 2011-04-04 09:50:34 UTC 
Description of problem:
I'm using a network proxy to call libguestfs' python interface (specifically: rpyc), and sfdisk rejects its list look-alike

It can be solved very simply by changing the code like:
-       return libguestfsmod.sfdisk (self._o, device, cyls, heads, sectors, lines)
+       return libguestfsmod.sfdisk (self._o, device, cyls, heads, sectors, list(lines))

It won't affect existing code, and it will accept any iterable instead of throwing a RuntimeError.

Comment 2 RHEL Program Management 2011-04-04 09:53:17 UTC 
Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

dev-ack+ for 6.2.

QA are telling me in other bugs that they don't want to
do any more changes to libguestfs for 6.1.

Comment 11 Jinxin Zheng 2011-07-07 09:22:52 UTC 
This is the reproducing python script:

$ cat sfdisk-test.py

import guestfs
g=guestfs.GuestFS()
g.add_drive('test.img')
g.launch()
trip=('1,100,83', '102,60,83', '200,50,83')
g.sfdisk('/dev/sda',0,0,0, trip)

$ truncate -s 1G test.img
$ python sfdisk-test.py

--
(outputs from libguestfs-1.7.17-17.el6)

Traceback (most recent call last):
  File "sfdisk.py", line 7, in <module>
    g.sfdisk('/dev/sda',0,0,0, trip)
  File "/usr/lib/python2.6/site-packages/guestfs.py", line 1684, in sfdisk
    return libguestfsmod.sfdisk (self._o, device, cyls, heads, sectors, lines)
RuntimeError: expecting a list parameter

resulting part table layout of -19 can be verified with sfdisk_l using guestfish.
