The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local area network, usually with Ethernet standard. Compared to Cisco Discovery Protocol (CDP) it’s not proprietary and can be used from different vendors.

Seems that nested virtualization is becoming popular on public cloud: first with Ravello, this year also on Azure, and now Google Compute Engine supports nested virtualization in beta.

Reading Time: 3 minutes

In a VMware infrastructure, when you build a new VM, the default compatibility level could depend on your vSphere version, from which client you are using (the legacy vSphere Client does not ask for VM virtual hardware version in the default wizard), but also from your cluster settings.
