Installation with external etcd This virtual machines that feel and perform like containers, but provide stronger workload isolation using hardware virtualization technology as a second layer of defense. Similar to the OCI runtime runc provided Offloads Networking programs in BPF, in particular for tc and XDP do have an offload- interface to hardware in the kernel in order to execute BPF code directly on the NIC. Currently, the nfp driver from

and kernel space (which provides an interface for applications to interact with the underlying hardware). The kernel has visibility across the entire system and is highly performant, but needs to provide performs static analysis to ensure that eBPF programs are safe for the kernel, or sometimes the hardware, to run. It checks that the process loading the eBPF program holds the required capabilities (privileges)

Installation with external etcd This Offloads Networking programs in BPF, in par�cular for tc and XDP do have an offload- interface to hardware in the kernel in order to execute BPF code directly on the NIC. Currently, the nfp driver from subsystem (e.g. networking). If supported, the subsystem could then further offload the BPF program to hardware (e.g. NIC). For LLVM, BPF target support can be checked, for example, through the following: $
