Re: [libvirt] [RFC] The Quest for Domain-IP Mapping Continues...

If you remember correctly, about 1.2 years ago, we had... https://www.redhat.com/archives/libvir-list/2013-September/msg00351.html In short, the patch proposed a generalized mechanism for finding out IP addresses, with flags for choosing method(s) (SNOOP|LEASE|AGENT). But since not all methods were supported (only qemu-ga worked), the API was deferred. After exploring a bit, it seems that in all, we can have: (i) Leases Method (ii) Qemu Guest Agent (iiI) DHCP Snooping (exists, but isn't publicly exposed?) (iv) ARP Snooping (we can ask the virtual network interfaces to share their arp tables with the public?) Now that we have the dhcp-leases API fully furnished, why not visit the qemu-guest-agent again? OP1. Should we have separate APIs + virsh commands for each one of these and then combine them together under virDomainInterfaceAddresses? - If each one has to be a different API and then combined later, then what should be the corresponding name for the virsh command for exposing the querying guest agent API? OP2. Implement virDomainInterfaceAddresses API with two flags, one for dhcp-leases and another for qemu-ga and keep adding others whenever they are completed?
