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
