Chapter 30. Deprecated Functionality in Red Hat Enterprise Linux 7 Symbols from libraries linked as dependencies no longer resolved by ld Previously, the ld linker resolved any symbols present in any linked library, even if some libraries were linked only implicitly as dependencies of other libraries. This allowed developers to use symbols from the implicitly linked libraries in application code and omit explicitly specifying these libraries for linking. For security reasons, ld has been changed to not resolve references to symbols in libraries linked implicitly as dependencies. As a result, linking with ld fails when application code attempts to use symbols from libraries not declared for linking and linked only implicitly as dependencies. To use symbols from libraries linked as dependencies, developers must explicitly link against these libraries as well. To restore the behavior of ld , use the -copy-dt-needed-entries command-line option. (BZ# 1292230 ) Windows guest virtual machine support limited As of Red Hat Enterprise Linux 7, Windows guest virtual machines are supported only under specific subscription programs, such as Advanced Mission Critical (AMC).

Note that other controllers from the mentioned drivers that are not listed here remain unchanged. Containers using the libvirt-lxc tooling have been deprecated The following libvirt-lxc packages are deprecated since Red Hat Enterprise Linux 7.1: libvirt-daemon-driver-lxc libvirt-daemon-lxc libvirt-login-shell Future development on the Linux containers framework is now based on the docker command-line interface. libvirt-lxc tooling may be removed in a future release of Red Hat Enterprise Linux (including Red Hat Enterprise Linux 7) and should not be relied upon for developing custom container management applications.
