My earlier testing for commit 34fa0de0 was done while starting just-built libvirt from an unconfined_t shell, where the fds happened to work when transferring to qemu. But when installed and run under virtd_t, failure to label the raw file (with no compression) or the pipe (with compression) triggers SELinux failures when passing fds over SCM_RIGHTS to svirt_t qemu. * src/qemu/qemu_migration.c (qemuMigrationToFile): When passing FDs, make sure they are labeled.
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
