Were you able to install the mxgpu-0.9.amd.iso successfully on your XenServer?
We installed Xenserver 7.2 with S7150.
Works fine Pass-through whole GPU Tonga XT GL. Performance like a GTX680.
But with MxGPU we get:
"Failed","Starting VM 'Windows 10.1'
Internal error: Subprocess exited with unexpected code 1; stdout = [ ]; stderr = [ modprobe: ERROR: could not insert 'gim': Operation not permitted ]
Time: 00:00:02","xen-graf17","Nov 17, 2017 1:45 PM"
Intel GVT-g virtual GPU works with this VM.
