Re: [vfio-users] VM doesn't boot if I use GPU passthrough

Hi Ruben, I guess your 750ti also has some audio device. You should pass through this too. It should be something like 01:00.1. There are many command line examples you can find about that. Also I´m not quite sure, if you should remove the x-vga=on. Regards Alex On Sun, Jan 17, 2016 at 11:12 PM,

[vfio-users] VM doesn't boot if I use GPU passthrough

2016-01-17 Thread Ruben Felgenhauer
Hi, I am trying to pass my nVidia GTX 750ti to my QEMU guest. Problem is: After the QEMU monitor pops up, nothing happens. The GPU's output is dead, and the vm won't be accessible via SSH anymore, so it's very likely that the VM isn't booting up at all. Also, there are no error messages from

Hi, my host system is linux-4.4.0 with qemu-2.5.0 and a 4-core i7. Linux is booted with isolcpus=1-3,5-7 to reserve 3 cores + threads for the Windows 10 VM. The VM's 3 cores(2 threads each) are pinned to the respective physical core/thread. The iothread is pinned to 1-3,5-7. When i start a simple

For the last few days, now, I've been trying to get a gpu passthrough to work on my computer, but I haven't been able to get the VM to output anything on my passthrough monitor at all since I started (I've had to either rely on a QXL adapteror just boot on the drive bare metal). Here's my situa
