Although I have Vt-d enabled in BIOS and see the IOMMU groups, the Web Console keep say the error " No IOMMU detected, please activate it. ". I found that the Intel HD Graphics 5500 was set to IOMMU Group [-1]. However, I still able to passthrough other device, but only the ...

It’s also important to slot the GPU into the proper PCIe slot on your motherboard. If the GPU is attached to the PCIe socket that has the same IOMMU group as the M.2 SSD, SATA controller, Ethernet jack, or other similar devices, attempting to passthrough the graphics card to a VM c...
hostpci0: 01:00.0,pcie=1 web页面模式添加 硬件->添加,选择PCI设备->选择,完成 如需更改为PCIE,可设置机器为q35 如果添加了PCI设备开启虚拟机正常使用那后面的就不需要看了 如果添加了PCI设备无法开启虚拟机的话需要允许不安全的中断 先验证IOMMU是否有效 ...

通过grub命令行参数激活ACS补丁，重启后记录IOMMU分组详情。根据记录，确定Group 15用于SATA控制器直通，Group 22、23用于显卡直通。显卡直通操作中，需明确识别直通的显卡设备。使用lspci命令筛选Radeon显卡，以便在PVE web UI中创建虚拟机vm101，配置直通相关组件，如USB0、主机PCI0和主机PCI1。注意，开启...

May be a dumb question, but if Proxmox uses IOMMU/VFIO for passthrough, I think you need to isolate the entire IOMMU group that the GPU belongs in for passthrough to work? I believe the Transfer Endpoint error is a network/data transfer error. So, if you're getting that when you try ...
