Interesting to hear your experience, it underlines how unraid would need to officially support GVT-G for it to be worthwhile for me. Funny how our use cases differ, my reason for wanting GVT-G is all about having quicksync in mulitple VMs, with no need for any direct display output!

Is there any news about GVT-G on unraid? I've upgraded my home server and want to consolidate all services into vms running off of it. I like the look of unraid but lack of official support for GVT-G would be a deal-breaker for me (need it for GPU assisted trans-coding on media and cctv servers). If I would need to re-complie the kernel myself at every update I may as well just roll my own solution with proxmox. @scorcho99 - you probably worked this out yourself since you last posted, but it isn't necessary to flash a modded bios just to increase the GPU aperture. If the Aperture Size option is hidden in your bios you can probably still modify it from a UEFI shell. Take a look at these instructions in the Opencore documentation. The opencore people are interested in changing a different setting (CFG Lock) just substitute "Aperture" for every instance of "CFG Lock" in the instructions, the process is the same. For example, following the instructions from opencore, I found this entry in the file created by running ifrextract on my bios setup.bin: 0x3A140 One Of: Aperture Size, VarStoreInfo (VarOffset/VarName): 0x2B9, VarStore: 0x1, QuestionId: 0x2759, Size: 1, Min: 0x0, Max 0x1F, Step: 0x0 {05 91 AC 07 AD 07 59 27 01 00 B9 02 14 10 00 1F 00} 0x3A151 One Of Option: 128MB, Value (8 bit): 0x0 {09 07 AE 07 00 00 00} 0x3A158 One Of Option: 256MB, Value (8 bit): 0x1 (default) {09 07 AF 07 30 00 01} 0x3A15F One Of Option: 512MB, Value (8 bit): 0x3 {09 07 B0 07 00 00 03} 0x3A166 One Of Option: 1024MB, Value (8 bit): 0x7 {09 07 B1 07 00 00 07} 0x3A16D One Of Option: 2048MB, Value (8 bit): 0xF {09 07 B2 07 00 00 0F} 0x3A174 One Of Option: 4096MB, Value (8 bit): 0x1F {09 07 B3 07 00 00 1F} 0x3A17B End One Of {29 02} So to increase the aperture on my system to 1024MB I issued the following command in the modified grub UEFI shell: setup_var 0x2B9 0x7 NOTE: this is BIOS specific, the settings NVRAM memory address will be different for every motherboard, possibly even changing between BIOS versions, so you need to follow the full instructions in the opencore documentation, just copy/pasting the above command I used for my board will not work and could leave your system unable to boot.
