Dear All, While working on a component handling container management I stumbled on a bug in the libvirt python bindings: basically the python bindings fail in properly translating the python file descriptor list to a native C array. The primary symptom was that inside the container the file descriptors are created but mapped to '/dev/null' instead of the original file descriptors This problem was discovered in libvirt 1.1.2 but the problem exists also in the current git head. I'm attaching a simple patch fixing the bug, and re-establishing the expected behaviour. I've also opened a bugzilla issue at https://bugzilla.redhat.com/show_bug.cgi?id=1021434 I hope this fix is acceptable and that it can be incorporated in the code base. :) Marian <libvirt-python-fix-lxc-fd-passing.patch> ~~~~~~~~~~~~~~~ Marian Neagul Universitatea de Vest din Timisoara Facultatea de Matematică și Informatică Centrul de Cercetare in Informatica marian(a)info.uvt.ro marian(a)hpc.uvt.ro
