      Not sure is it an issue. Agent itself is working.

      Is this a graphical (desktop) based VM running the agent?

      @olivierlambert If his VM is a desktop graphical Ubuntu then, it’s Kernel will be regularly updated with each new standard lifecycle point be an upgraded HWE kernel. So will be frequently getting this message, new info in the kernel. HWE kernels are default in modern Ubuntu desktop environments!

          @Tristis-Oris yes it is likely you're using a newer kernel, we likely need to rebuild the agent using a newer version of the netlink crate.

            @olivierlambert Error causes tools to fail to load... >256 IP addresses on an interface (IPv4 and IPv6):

            xen-guest-agent[514]: Error: Custom { kind: OutOfMemory, error: "no free slot for a new IP address" }

            Best is to account for all the IP addresses.... second best is to ignore the extra IP addresses and not fail and exit.
