Re: [libvirt] libvirt default network



Hi again

So we did 2 changes in the specfile that are described below
This has gone through all our nightlies and all, so that works for us

I’m sorry that I can’t seem to get git send-email to work on my mac (complains about missing perl modules ?!?)
Fortunately the changes I did are so simple, I hope you can use the following material

http://git.onelab.eu/?p=libvirt.git;a=commitdiff;h=a0e03e6894d8e8486e79531967b92b83d6d59b86

http://git.onelab.eu/?p=libvirt.git;a=commitdiff;h=7f0c4d07b5faac3f0fb07cd8240f5ae0e1063560

Of course I can post using some other scheme if that’s not working for you guys 

Thanks — Thierry
