Description of problem:
Whenever I start a Xen domain created using virt-install, there are SELinux denials.

How reproducible:
Every time

Steps to Reproduce:

SELinux denials reported (I'm in permissive mode at the moment, until these
problems are resolved)

Expected results:
Domain starts normally

Did this actually block something from working?  If you try this in enforcing
mode do you see errors?  This looks like xen is leaking an open descriptor to
the xen_image_t file.  There is no reason ifconfig should ever need to
read/write this disk image.  I believe this should work in enforcing mode.

Yes, there are errors when running in enforcing mode, though things do appear to
be working.

QEMU was leaking file handles to the networking scripts which caused SELinux
errors. This was fixed in Xen 3.0.3-7.fc6

* Tue Mar  6 2007 Daniel P. Berrange <berrange> - 3.0.3-7.fc6
- Ensure PVFB daemon terminates if domain doesn't startup (bz 230634)
- Fix ia64 shadow page table mode
- Close QEMU file handles when running network script

Please upgrade & confirm that the errors went away.

Close file handles before running network scripts

This is the patch applied upstream & to Fedora to fix QEMU filehandle leak
