I think you should post to fedora-xen@xxxxxxxxxx and possibly 
CC fedora-virt@xxxxxxxxxxx

I was using the default libvirt from F11, but I manually added the bugfix patch:

- Download libvirt src.rpm:
  
ftp://ftp.funet.fi/pub/mirrors/fedora.redhat.com/pub/fedora/linux/updates/11/SRPMS/libvirt-0.6.2-14.fc11.src.rpm

- install it: "rpm -i libvirt-0.6.2-14.fc11.src.rpm"

- Copy & paste the patch to a file 
/root/rpmbuild/SOURCES/libvirt-bugfix-custom.patch from
  
http://libvirt.org/git/?p=libvirt.git;a=blobdiff;f=src/xend_internal.c;h=55ffd3f9a5004e681c8ffb2279d27965eb42e956;hp=b211bb6293355bf68e33f56f947021bd7bb8e675;hb=14435163a086c0bcdff04308077fa46a5fa08bb0;hpb=fd90b67afe59265327dde7e447ea847687bd4e8d

- Edit /root/rpmbuild/SPECS/libvirt.spec and add the patch like other
  patches are added. You need to add one line to two different places.

- Run "rpmbuild -bb libvirt.spec"

- Install the bugfixed rpms from /root/rpmbuild/RPMS/i586/
