This was already fixed as a part of the original backport but the build wasn't done yet.

conf: Fix backport of metadata API code
https://bugzilla.redhat.com/show_bug.cgi?id=1115039
RHEL-only, problems introduced in backport
The clang checker found a few issues introduced by the backports of the
metadata code. As the code is already in dist-git this patch fixes up
the problems pointed out by Clang:
1) few possible strdup()'s of NULL argument
2) false positive as Clang considered the def local variable in
virDomainObjGetMetadata as uninitialized

Description of problem: On a Fedora20 host, when create a connection to connect libvirtd on a RHEL6.6 server via virt-manager, which will crash the server libvirtd. Version-Release number of selected component (if applicable): Client: virt-manager-1.0.1-3.fc20.noarch Serevr: libvirt-0.10.2-41.el6.x86_64 kernel-2.6.32-491.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1. Create connection(rhel6.6 host) via virt-manager on a FC20 host. 2. 3. Actual results: virt-manager raise: Error polling connection 'qemu+ssh://root.7.209/system': internal error: client socket is closed Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 343, in _handle_tick_queue conn.tick(**kwargs) File "/usr/share/virt-manager/virtManager/connection.py", line 1209, in tick raise e # pylint: disable=raising-bad-type libvirtError: internal error: client socket is closed And check the libvirtd status on remote server: # service libvirtd status libvirtd dead but pid file exists Expected results: Connect successfully, and libvirtd on the server will not crash.
