methods:
(i) Querying qemu-guest-agent
(ii) Getting info from dnsmasq.leases file
(iii) Using the nwfilter to snoop the traffic
If no method is mentioned, qemu-guest-agent will be used.
Previous attempts by Michal had used structs and xml. Structs bring in
restrictions and xml has to be parsed. Hence I am not planning to
continue with either of these.
As a start, I would like to know your comments about my API which
queries the qemu-guest-agent and returns the results in
virTypedParameter **params.
Format(JSON) in which the qemu guest agent returns info:
[{"name":"lo",
"ip-addresses":
[{"ip-address-type":"ipv4","ip-address":"127.0.0.1","prefix":8},
{"ip-address-type":"ipv6","ip-address":"::1","prefix":128}],
"hardware-address":"00:00:00:00:00:00"},
{"name":"eth0",
"ip-addresses":
[{"ip-address-type":"ipv4","ip-address":"192.168.122.42","prefix":24},
{"ip-address-type":"ipv6","ip-address":"fe80::5054:ff:fe09:d240","prefix":64}],
"hardware-address":"52:54:00:09:d2:40"}]
//Possible 1-D Structure (A little hassle to maintain)
