82576在KVM虚拟机下使用网卡的SRIOV功能直通进虚拟机,减少使用Proxmox VE虚拟网卡的NAT功能,提高网卡性能,降低CPU占用。
一、pve介绍
简单来说:Proxmox VE是一个集成OPENVZ 支持KVM应用的环境。
二、单根I/O虚拟化(SRIOV)介绍
三、基础环境以及软件安装
Proxmox VE 5.4
CPU:E5645*2
网卡:intel 82576
3.1 软件安装
安装基本的软件
root@pve:~# apt update
root@pve:~# apt-get install net-tools vim ethtool -y\
3.2 打开IOMMU
GRUB_CMDLINE_LINUX_DEFAULT=" intel_iommu=on pcie_acs_override=downstream"
GRUB_CMDLINE_LINUX_DEFAULT=" amd_iommu=on pcie_acs_override=downstream"
root@pve:~# update-grub
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
root@pve:~# update-initramfs -u -k all
root@pve:~# reboot
3.3 检查IOMMO功能是否开启
root@pve:~# dmesg | grep -e DMAR -e IOMMU -e AMD-Vi

options vfio_iommu_type1 allow_unsafe_interrupts=1
3.3 部署SRIOV
root@pve:~# echo "options igb max_vfs=6,6,6,6,6,6" > /etc/modprobe.d/igb.conf
root@pve:~# depmod -a
root@pve:~# update-initramfs -u
root@pve:~# reboot
解释一下,max_vfs=6,6,6,6,6,6:
1.1 这条语句说明最大的虚拟网卡是6个,也就是虚拟6个
1.2 6,6···说明我这里有6个intel 82576网卡,每个网卡虚拟出6个,总共是36个虚拟网卡
3.4 检查虚拟网卡
