I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

Hi,all I have tried to passthrough GPU card(Nvidia quadro 4000) on the latest Xen unstable version (QEMU is using Qemu-upsteam-unstable, not traditional Qemu). This issue as below: Windows7 64-bit guest will blue screen when GPU passthrough configure 4g memory,blue screen code is 50, and SUSE 11 64-bit guest will always stay at the grub screen. I noticed that it will relocate RAM that
