chocol4tebubble5 Posted May 4, 2017 Share Posted May 4, 2017 Hello, I am trying to passthrough a GTX 760 to my Ubuntu Server VM, using an ASRock X99 Extreme4 motherboard, E5-2683 V3 and an NVS 440 for console output. The VM will boot to GRUB, and after selecting Ubuntu, it will display a black screen. Here is the system log: May 4 17:52:05 unraid-srv kernel: vgaarb: device changed decodes: PCI:0000:06:00.0,olddecodes=io+mem,decodes=io+mem:owns=io+mem May 4 17:52:06 unraid-srv kernel: br0: port 2(vnet0) entered blocking state May 4 17:52:06 unraid-srv kernel: br0: port 2(vnet0) entered disabled state May 4 17:52:06 unraid-srv kernel: device vnet0 entered promiscuous mode May 4 17:52:06 unraid-srv kernel: br0: port 2(vnet0) entered blocking state May 4 17:52:06 unraid-srv kernel: br0: port 2(vnet0) entered forwarding state May 4 17:52:08 unraid-srv kernel: vfio_ecap_init: 0000:06:00.0 hiding ecap 0x19@0x900 May 4 17:52:08 unraid-srv kernel: pmd_set_huge: Cannot satisfy [mem 0xc8000000-0xc8200000] with a huge-page mapping due to MTRR override.
