Hi, I'm trying to use KVM virtualization at home and I've run into what I think is a limitation of my hardware. I'm trying to pass a PCI card (WinTV NOVA-T 500) through to a guest OS but I get the error 'IOMMU not found'. Now I've read that this is because my motherboard does not have an IOMMU to perform hardware accelerated device virtualization. I have an AMD based system and apparently they call it AMD-Vi and Intel call it VT-d. Now, my 790GX based board does not have IOMMU, but the latest chipset, the 890FX, apparently does, it has IOMMU v1.2 Before I go and spend lots of money on what it a very expensive board, can somebody confirm that an AMD 890FX based board with a Phenom II X3 processor with Ubuntu 10.04 server 64bit using KVM/QEMU will allow me to passthrough a PCI card to the guest OS? On another note, now that I've subscribed to this mailing list I notice that there is an email named "AMD IOMMU Emulation" Is that what I think it is and can I compile up a patched version for my server? Many Thanks, James. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
