[libvirt] [PATCH 0/2] tell dnsmasq not to forward PTR queries

[Gene Czarcinski]

I would appreciate it if the libvirt developers who are attempting to 
provide overall guidance to give some thought to the two patches.

I have done a bunch of testing and both patches work as intended ... 
they only deal with the dns service provided by dnsmasq.

When dsnmasq is providing both dns and dhcp services, this makes sense.  
But how about the situations where dnsmasq is only listening?

The earlier patches I submitted for not forwarding A, AAAA, or MX dns 
queries because there was no way for an upstream dns server determining 
what should be forwarded to the "Big Eye" Internet. [why isn't 
"test.virt" as good a FQDN as anything else]

But, the same is not true for private network PTR queries ... dnsmasq 
"bogus-priv" can indicate not to forward them.  There is also some 
discussion about implementing a similar capability for IPv6.

Anyway, here they are for your consideration.
