Hi

I find that the HOW-TO for VT-d pass through on linux-kvm.org asks for
Interrupt Remapping to be enabled in the kernel. However Interrupt
Remapping is dependent on x86_64 (DMAR was also dependent but I guess
the 2.6.30 kernel allows it for 32 bit systems)

Does that mean I will not be able to try device pass through on 32 bit
systems?

Thanks in advance
Subash

Device pass through doesn't depend on interrupt remapping. Interrupt remapping is optional. I will change the VT-d HOW-TO to clarify it.
