Dear List, Recently I read an article [1] about how to use KVM and VGA passthrough to create multiple GPU accelerated VM's for use in gaming or as virtual workstations: [1] http://www.pugetsystems.com/labs/articles/Multiheaded-NVIDIA-Gaming-using-Ubuntu-14-04-KVM-585/ I'm planning on building a KVM workstation to do this using CentOS 7 or Ubuntu 14.04 LTS as the base virtualization host and then an Intel Xeon CPU and two Nvidia GeForce GTX 750's as GPU's for the virtual machines...

...VM from a shell script, much less being able to run several VMs that each have a pass-through. As for details missing from my previous mail: This is an Ubuntu 15.04 host running several Windows 10 guests. The entire kvm command line I have running is from this guide at Puget Systems: https://www.pugetsystems.com/labs/articles/Multiheaded-NVIDIA-Gaming-using-Ubuntu-14-04-KVM-585/ I have discovered several problems with this guide, in particular that I can remove the pci_stub ids from /etc/initramfs-tools/modules and the virtual Windows host continues to work just fine. So, now I'm back to scratch...

I would really appreciate some pointers on what I am doing wrong here. I have a need to run multiple virtual guests which have each their own GPU and some USB controllers passed-through. I am able to run one of the guests like this (assuming vfio stuff has happened elsewhere), but I would prefer to use virsh: kvm -M q35 -m 8192 -cpu host,kvm=off \ -smp 4,sockets=1,cores=4,threads=1 \ -bios
