ubuntu18.04 虚拟机上编译DPDK
先去github上下载DPDK源码包：https://github.com/DPDK/dpdk/tree/v19.05-rc1
下载完成后，拷贝dpdk-releases.zip到虚拟机上.
虚拟机命令行输入：
unzip dpdk-releases.zip
cd usertools/
因为是x86电脑，所以选择16。[16] x86_64-native-linuxapp-gcc
./dpdk-setup.sh
16
报错，显示
/home/chenhao/dpdk/dpdk-releases/lib/librte_eal/linuxapp/eal/eal_memory.c:33:10: fatal error: numa.h: No such file or directory
#include
安装libnuma-dev即可
apt-get install libnuma-dev
安装qemu
sudo apt install qemu-system-x86
把网卡绑定到dpdk，通过vfio-pci，结果报错：
:~/dpdk/dpdk-releases/usertools$ ./dpdk-devbind.py --bind=vfio-pci 0000:00:08.0
Error - no supported modules(DPDK driver) are loaded
搜索资料，说是没有加载igb_uio。
运行/dpdk-releases/usertools目录下的dpdk-setup.sh，选项[19] Insert IGB UIO module
插入igb_uio，
./dpdk-setup.sh
19
报错，显示
## ERROR: Target does not have the DPDK UIO Kernel Module.
To fix, please try to rebuild target.
搜索资料，说是没有加载uio。
sudo modprobe uio
插入igb_uio：
cd ~/dpdk-releases/x86_64-native-linuxapp-gcc/kmod
$ sudo insmod igb_uio.ko
重新绑定网卡到dpdk，结果显示无法绑定：
:~/dpdk/dpdk-releases/usertools$ ./dpdk-devbind.py --bind=vfio-pci 0000:00:08.0
Routing table indicates that interface 0000:00:08.0 is active. Not modifying
关闭网卡：
sudo ifconfig enp0s8 down
重新用脚本绑定到dpdk，报错，显示：
:~/dpdk/dpdk-releases/usertools$ ./dpdk-devbind.py --bind=vfio-pci 0000:00:08.0
Error: unbind failed for 0000:00:08.0 - Cannot open /sys/bus/pci/drivers/e1000/unbind
可以重新打开一个终端，通过dmesg命令打印串口信息查看报错原因。
试过sudo权限后，成功解绑 ：
sudo ./dpdk-devbind.py --unbind 0000:00:08.0
绑定vfio-pci失败，改绑igb_uio成功：
VirtualBox:~/dpdk/dpdk-releases/usertools$ sudo ./dpdk-devbind.py --bind=vfio-pci 0000:00:08.0
Error: bind failed for 0000:00:08.0 - Cannot open /sys/bus/pci/drivers/vfio-pci/bind
VirtualBox:~/dpdk/dpdk-releases/usertools$
VirtualBox:~/dpdk/dpdk-releases/usertools$ sudo ./dpdk-devbind.py --bind=igb_uio 0000:00:08.0
查看网卡绑定状态如下：
VirtualBox:~/dpdk/dpdk-releases/usertools$ ./dpdk-devbind.py --status
