Description

I had an A4-5300+A85X system which support IOMMU and is enabled in BIOS. When I try to let the guest access some I/O directly via pci passthrough,sometimes the vboxpci says iommu_attach_device fail(just like  https://forums.virtualbox.org/viewtopic.php?f=7&t=51143),but sometimes success. And the guest could detect the device but does not receive any interrupt. But I am failed to building VirtualBox by myself,any advice??
