Running 'git clone' in virt-builder or virt-customize results in an error message
Last modified: 2016-11-03 13:57:58 EDT
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
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.
To the reporter, please try the preview packages here which should already fix this issue: https://people.redhat.com/~rjones/libguestfs-RHEL-7.3-preview/
