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 Barak Korren 2016-02-11 09:48:41 UTC 
Description of problem:
Running 'git clone' in virt-builder or virt-customize results in the following error message:

  Error reading command stream

This happens regardless of the git repo used.
This was tested for both RHEL and CentOS guest images, the host is RHEL7.2

Version-Release number of selected component (if applicable):
  libguestfs-tools-c-1.28.1-1.18.el7.x86_64

How reproducible:
  virt-builder centos-7.2  \
    --install git \
    --run-command 'git clone https://github.com/ifireball/scripts'

Actual results:
  Error message

Expected results:
  git repo cloned into VM image
Comment 1 Pino Toscano 2016-02-11 13:32:45 UTC 
This is due to the fact that we're not providing an open stdin when running commands in the appliance, as reported in bug #1280029.

This can be reproduced on a RHEL/CentOS 7.2 host with the following command:

  $ git clone https://github.com/ifireball/scripts <&-
  Cloning into 'scripts'...
  Error reading command stream

(the <&- tells bash to close the file descriptor 0, which is stdin)

This has been fixed upstream since 1.31.28, and it will be fixed by the rebase (bug #1218766) for RHEL 7.3.
Comment 2 Richard W.M. Jones 2016-02-11 13:39:58 UTC 
To the reporter, please try the preview packages here which
should already fix this issue:

Comment 3 Xianghua Chen 2016-05-31 04:59:27 UTC 
Verified with the packages:
libguestfs-1.32.4-3.el7.x86_64
libguestfs-tools-c-1.32.4-3.el7.x86_64

Verify steps:
1. # virt-builder centos-7.2      --install git     --run-command 'git clone https://github.com/ifireball/scripts'
[   4.6] Downloading: http://libguestfs.org/download/builder/centos-7.2.xz
[   5.5] Planning how to build this image
[   5.5] Uncompressing
[  16.5] Opening the new disk
[  20.2] Setting a random seed
[  20.2] Installing packages: git
[  44.8] Running: git clone https://github.com/ifireball/scripts
[  48.2] Setting passwords
virt-builder: Setting random password of root to 4yK3APSs3jSbb5g4
[  49.7] Finishing off
                   Output file: centos-7.2.img
                   Output size: 6.0G
                 Output format: raw
            Total usable space: 4.8G
                    Free space: 3.8G (78%)


The command finished successfully, and the following error didn't occurred:
Cloning into 'scripts'...
Error reading command stream
libguestfs: trace: download = 0
virt-builder: git clone https://github.com/ifireball/scripts: command exited with an error


So Verified.
