Re: [libvirt] PATCH [0/2]: Deprecate conn, dom, net virterror fields



Hi, Rich

Your code seems to make compilation trouble.
http://builder.virt-manager.org/module-libvirt--devel.html


http://git.et.redhat.com/?p=libvirt.git;a=commitdiff;h=fc949fa7b7e043401f4c53374fa1939c348a911f;hp=a295031a35110112ecc92aca1e21428435ec8e86

Thanks
