我正在使用 Proxmox 构建一个小型家庭服务器。在我的系统中，我安装了：
- 华硕 A520m-k
- 锐龙 5 Pro 5650G
- 1x SATA 控制器（通过 PCIe）
- 1 个 PCIe 转 M.2 适配器，带 NVME 驱动器
现在我想设置一个 NAS，在那里虚拟化 TrueNas Core。我想通过 IOMMU 将带有 2 个 2TB HDD 的 SATA 控制器传递到 TrueNas 实例。
我已经在主板的 UEFI 中启用了 IOMMU，并且还根据官方 Proxmox VE Wiki 设置了 IOMMUhttps://pve.proxmox.com/wiki/Pci_passthrough

IOMMU Group 8 06:00.0 SATA controller [0106]: ASMedia Technology Inc. Device [1b21:1064] (rev 02)
我想要直通的 SATA 控制器是来自ASMedia Technology Inc.
出现的问题是，当我将控制器分配给我的 VM（当前仅运行 ubuntu）并启动它时，Proxmox VE 虚拟机管理程序有点崩溃，虽然不是完全崩溃，但我仍然可以通过键盘和鼠标使用 Proxmox 的 debian shell，但 WEB 界面不再处于活动状态，ssh 也不起作用。我对 IOMMU 一无所知，但我认为发生的事情是，Ethernet controller同样位于 IOMMU 组 8 中的设备也会传递到 VM，因此我的虚拟机管理程序缺少与路由器的连接。（所以我还认为位于组 8 中的所有设备都将传递给 VM）。
我不知道我的想法是否正确，但是我该如何修复它，以便我只能通过我的硬盘驱动器传递 SATA 控制器。
