[libvirt-php] libvirt_domain_interface_addresses() only returns only on IP address for NICs with multiple IPs

[Fernando Casas Schössow]

Hi,

While using the function libvirt_domain_interface_addresses() with qemu 
guest agent as the source, for interfaces with more than one IP 
address, the function will only return one IP.

Example code:

$netdetails = libvirt_domain_interface_addresses($vmres, 2);
foreach ($netdetails as $nic) {
	print_r($nic);
}


Example output:

Array
(
    [name] => eth0
    [hwaddr] => 52:54:00:12:b9:22
    [naddrs] => 2
    [addrs] => Array
        (
            [addr] => fe80::5054:ff:fe12:b922
            [prefix] => 64
            [type] => 1
        )

)
Array
(
    [name] => eth1
    [hwaddr] => 52:54:00:8e:b0:35
    [naddrs] => 2
    [addrs] => Array
        (
            [addr] => fe80::5054:ff:fe8e:b035
            [prefix] => 64
            [type] => 1
        )

)

As you can see for this guest the function returns two interfaces (eth0 
and eth1). For both interfaces naddrs => 2 which is correct because 
both interfaces have an ipv4 and an ipv6 address but the addrs array 
only contains the ipv6 address information while the ipv4 address 
information is missing.
