又學到一個小知識
原因是因為 -mfpu=neon-fp-armv8 是 arm32 compiler option ARM64 使用 Linux ABI 那邊就規範要支援 Floatpoint 和 ASIMD(也就是 neon 的 64bit 版 )
不要用 -mfpu 指令就可以了

Install Kubernetes on Ubuntu 18.04 is very easy now, but only for x86 platform. If on ARM64 environment, it might have some other problem.
Some old article mentioned a lot of information but software version is too old for deploy a new version software.
After a lot of time to have research, here is instruction for how to install Kubernetes on ARM64 Ubuntu 18.04

DPDK is a very popular infrastructure in high speed packet process domain, some applications will used the same architecture to process packet, like EPC.
For Ubuntu 18.04, it used dpdk 17.11, it not good for some other application like dpdk pktgen, but enough for testpmd and l3fwd test. here is some personal note for setup whole environment.

替代方案就是用 Virt Manager
