i've reported this issue before, so i guess this is a regression. looks like the python bindings for 0.9.3 are leaking file descriptors:
root@cloud1:~# python Python 2.6.6 (r266:84292, Dec 26 2010, 22:31:48) [GCC 4.4.5] on linux2 Type "help", "copyright", "credits" or "license" for more information.
import libvirt libvirt.getVersion() 9003 def openclose(): ... c = libvirt.open('qemu:///system') ... c.close() ... import os os.system('lsof -p %d | wc -l' % os.getpid()) 37 openclose() os.system('lsof -p %d | wc -l' % os.getpid()) 40 openclose() os.system('lsof -p %d | wc -l' % os.getpid()) 43
every time I open and close a connection to libvirt, i loose 3 file descriptors. these are a socket and two fifo pipes. i'm using the -3 build on debian sid.
can someone test this on a fedora machine? curious if this is something inside libvirt or a problem with the build...
I can reproduce this with libvirt 0.9.3, but not with current git. Therefore, this problem seems to be fixed in git. I've you want to backport the fix to libvirt 0.9.3 you should be able to find it using git bisect. That one of the FDs is a socket suggests that this is related to the remote driver. -- Matthias Bolte http://photron.blogspot.com
