This bug still exists in 10.10 and 0.8.3. All available docs that I've seen refer to /etc/sasl2/libvirt.conf, but strace still reports that only /etc/sasl/libvirt.conf (and /usr/lib/sasl2/libvirt.conf) are actually accessed.
Linking /etc/sasl2 to /etc/sasl solved the problem for me, and I've got Kerberos working with libvirt now.
