Autodetect IPs used inside the VM #7142
Description
Activity
Could add a "search by IP" function as well.
Hi @NuxRo - I’m Adi, a 2nd year Computing student at Imperial College London. I’m interested in this project and will be developing my proposal over the next few days. I have already been in touch with Nicolás Vazquez but thought it worthwhile to introduce myself here too. Apologies for starting so late; I’ve been busy with a university project deadline but will do my utmost best to catch up. Looking forward to communicating with you about this feature!
Reacted by NuxRo@adi4656 it makes sense to introduce yourself on dev@cloudstack.apache.org, but good luck with your assignment. Let us know how you fare ;)

With regards to IP info reporting, Cloudstack relies entirely on it's DHCP data bases and so on. When this is not available (L2 networks etc) no IP information is shown for a given VM.
I propose we introduce a mechanism for "IP autodetection" and try to discover the IPs used inside the machines by means of querying the hypervisors. For example with KVM/libvirt we can simply do something like this:
The above command queries the qemu-guest-agent inside the Windows VM. The VM needs to have the qemu-guest-agent installed and running as well as the virtio serial drivers (easily done in this case with virtio-win-guest-tools.exe ) as well as a guest-agent socket channel defined in libvirt.
Once we have this information we could display it in the UI/API as "Autodetected VM IPs" or something like that.
I imagine it's very similar for VMWare and XCP-ng.
Thank you
