PVE排查内存问题

背景

PVE经过一系列的优化后，CPU 温度降到了 55 °C ~ 75 °C。但是我我发现我 32G的内存只有16G，另外一个内存好久之前就无法识别了。

环境信息

PVE版本信息

root@:~#  pveversion -v
proxmox-ve: 8.4.0 (running kernel: 6.8.12-15-pve)
pve-manager: 8.4.14 (running version: 8.4.14/b502d23c55afcba1)
proxmox-kernel-helper: 8.1.4
proxmox-kernel-6.8: 6.8.12-15

内存信息(修复后显示正常)
