Hi, I've been playing with X in domU again, got succesfull once, but find it hard to reproduce because nvidiafb keeps locking up. My setup is a Centos5 system, using 2 nvidia cards, and 2 usb cards. I assign the PCI Graphics card and one usb card to DomU using pciback, which seems to work great. The problem occurs when I want to modprobe nvidiafb in DomU, almost all the time it locks up, thus I am unable to use it as a display device for X. I tried with and without X running in dom0 (using nv driver in dom0 by the way) I also tried to start X in domU with nv driver, but that gives a different error: Fatal server error: xf86MapVidMem: Could not mmap framebuffer (0x000a0000,0x20000) (Bad address) Regards, Mark.
