Created attachment 814505 [details] A patch fixing the problem Description of problem: The libvirt python api fails to properly pass file descriptors to the libvirt daemon. The problem resides in the following functions (in ): 1. libvirt_virDomainCreateWithFiles 2. libvirt_virDomainCreateXMLWithFiles Version-Release number of selected component (if applicable): All current releases providing FD passing to containers How reproducible: Try to pass file descriptors to a container using the aforementioned functions. The fds are created but mapped to /dev/null instead to the correct FD's Actual results: Passed FD's are mapped to /dev/null Expected results: Passed FD's should be mapped to the original FD Additional info:
I posted the patch on mailing list for you and reviewed it myself. I'll also push it if it is accepted. Feel free to post (unified) patches (against git master) yourself in the future when you have a fix. It will speed up the things.
