4.12 Unable to create Oracle Linux 7 LXC containers on NFS

The creation of Oracle Linux 7 containers fails when the root file system (/container) is hosted on an NFS share. This problem occurs because the iputils package in Oracle Linux 7 releases, (Updates 4 and 5) is built to use the Linux file extended attributes [xattr(7)] security capabilities(7). Because the NFS protocol does not support these file capabilities, the iputils package might not be installed into an NFS files system. For example, when attempting to create an Oracle Linux 7 Update 4 container, the installation fails while installing the iputils package, producing the following error:

Error unpacking rpm package iputils-20121221-7.el7.x86_64
error: unpacking of archive failed on file /usr/bin/ping: cpio: cap_set_file
error: iputils-20121221-7.el7.x86_64: install failed

Similar issues are seen when attempting to install the initscripts and systemd packages while creating an Oracle Linux 7 Update 3 container.

This issue occurs on both NFSv3 and NFSv4.

Oracle Linux 6 containers are not affected. LXC is available as a technology preview in this update. Note that some functionality may not work correctly.
