* 背景
** Mellanox网卡实验
*  现状
** 40.47服务器上安装有两块Mellanox网卡自环连接在一起
** 40.29服务器已安装为PVE系统
* 任务
** 将40.47上的一块Mellanox网卡安装至40.29服务器
** 将40.47上和40.29上的Mellanox网卡直连
** 40.29上新建虚拟机并将Mellanox网卡透入该虚拟机
** 提供新建虚拟机的IP和登陆方式**zhangshuo** commented on *2021-10-22T15:21:40.953+0800*:
第一步将40.47的一块mellanox网卡拆下安装到40.29上。
第二步两台服务器的mellanox网卡用光纤直连。
第三步安装好后告知我我来试试从pve加载网卡创建虚拟机
第四步测试如果pve无法加载这块卡需要重新安装centos7.4
[~majingxue]麻烦安排人配合安装连线,谢谢~

已经将40.47上一张Mellanox网卡插在40.29服务器的单独一个pic插槽上且40.47服务器的Mellanox网卡的enp130s0f0与enp130s0f1网口分别与40.29新插的Mellanox网卡的两个网口具体网卡名称[~zhangshuo]补充)使用光纤直连。

[~zhangshuo] 尹付涛已提供另一端连接Mellanox网卡的虚机IP为42.12。
目前网卡透入虚机的方式不对使用ethtool工具查看到网卡使用的驱动为virtio_net请参考https://docs.mellanox.com/pages/releaseview.action?pageId=15052991中的说明调整网卡到虚机的设置
