Comment # 1 on bug 1031778 from Liang Yan

After attach debug in dnsmasq, I found it was broken when try to read a config
file, return code showed no access permission. Since dnsmasq is a fork child
process from libvirt, the process also needs libvirt's ownership. Thing went
through after I changed ownership back manually. I close it because found the
root reason and it is really difficult to to reproduce why file ownership been
changed.
