Ok, if "dmesg | grep -e DMAR -e IOMMU " doesn't give you any output, it doesn't make sense to perform any further tests untill you have fixed this. It will not work without this. > The Linux distribution is Ubuntu server 9.10 with different kernel test: > 1. the original 2.6.31-19-server ; > 2. 2.6.31-19-server ricompiled with mudules Support for DMA Remapping > Devices;Enable DMA Remapping Devices;PCI Stub driver;Support for Interrupt > Remapping ; > 3. 2.6.32.8 ricompiled with mudules Support for DMA Remapping Devices;Enable > DMA Remapping Devices;PCI Stub driver;Support for Interrupt Remapping ; In that case you're down to two problems, AFAIK: 1. Your hardware (your chipset) doesn't support VT-d. 2. VT-d support is not enabled in BIOS, not supported in BIOS or BIOS implementation is buggy. What motherboard do you have?
