Hi list
These I'm checking PCI Passthrough to PV domU, and I found when the memory larger than 3G, the PCI passthrough will not successfully. I got some information from the google. Some guys said it's a bug, and has already fixed, Why do I still meet this problem? What should I do?
please refer to :

Bug 1673 - 3GB memory restriction for pv domU with PCI
