When creating new /dev/* for qemu, we do chown() and copy ACLs to create the exact copy from the original /dev. I though that copying SELinux labels is not necessary as SELinux will chose the sane defaults. Surprisingly, it does not leaving namespace with the following labels: crw-rw-rw-. root root system_u:object_r:tmpfs_t:s0 random crw-------. root root system_u:object_r:tmpfs_t:s0 rtc0 drwxrwxrwt. root root system_u:object_r:tmpfs_t:s0 shm crw-rw-rw-. root root system_u:object_r:tmpfs_t:s0 urandom As a result, domain is unable to start: error: internal error: process exited while connecting to monitor: Error in GnuTLS initialization: Failed to acquire random data. qemu-kvm: cannot initialize crypto: Unable to initialize GNUTLS library: Failed to acquire random data. The solution is to copy the SELinux labels as well. Reported-by: Andrea Bolognani <abologna@redhat.com> Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
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.
