ubuntu16.04 dpdk-v19.08
sudo apt install make gcc g++ gdb libnuma-dev git vim
sudo ln -s /usr/bin/python3 /usr/bin/python修改虚拟机
ethernet1.virtualDev = "e1000"
修改为
ethernet1.virtualDev = "vmxnet3"
vmxnet3支持多队列网卡
修改支持巨页
其次,通过命令sudo vim /etc/default/grub 将参数GRUB_CMDLINE_LINUX=""在其后面加上
default_hugepages=1G hugepagesz=2M hugepages=1024 isolcpus=0-2
再执行命令:sudo grub-mkconfig -o /boot/grub/grub.cfg
在 GRUB_CMDLINE_LINUX参数，添加 net.ifnames=0 biosdevname=0,使得网卡名称从0开始命名。
重启主机
git clone https://github.com/DPDK/dpdk.git
git checkout v19.08
git checkout -b v19.08进入dpdk目录：cd dpdk 然后执行./usertools/dpdk-setup.sh 选择39编译
