# PVE VM 不支援 AVX 指令集解決方案

# 前言

前陣子在 PVE 上開了 VM 架設 Docker MongoDB Server，遇到了以下 Log

mongodb          | /bin/bash: line 1: mongo: command not found
mongodb          |
mongodb          | WARNING: MongoDB 5.0+ requires a CPU with AVX support, and your current system does not appear to have that!
mongodb          |   see https://jira.mongodb.org/browse/SERVER-54407

重點在於 MongoDB 5.0+ requires a CPU with AVX support

居然！！PVE 預設開啟的 VM 沒有 AVX 指令集

# 解決方法

回到 PVE VM 上的硬體畫面，更改 CPU 的配置，將類別從 KVM 轉換成 Host 就可以了
