By querying the qemu guest agent with the QMP command
"guest-network-get-interfaces" and converting the received JSON
output to structured objects.
Although "ifconfig" is deprecated, IP aliases created by "ifconfig"
are supported by this API. The legacy syntax of an IP alias is:
"<ifname>:<alias-name>". Since we want all aliases to be clubbed
under parent interface, simply stripping ":<alias-name>" suffices.
Note that IP aliases formed by "ip" aren't visible to "ifconfig",
and aliases created by "ip" do not have any specific name. But
we are lucky, as qemu guest agent detects aliases created by both.
src/qemu/qemu_agent.h:
* Define qemuAgentGetInterfaces
src/qemu/qemu_agent.c:
* Implement qemuAgentGetInterface
src/qemu/qemu_driver.c:
* New function qemuGetDHCPInterfaces
* New function qemuDomainInterfaceAddresses
src/remote_protocol-sructs:
* Define new structs
tests/qemuagenttest.c:
* Add new test: testQemuAgentGetInterfaces
Test cases for IP aliases, 0 or multiple ipv4/ipv6 address(es)
