Bug Description
My server is :
PowerEdge T630
2x Intel(R) Xeon(R) CPU E5-2623 v4 @ 2.60GHz
128G of ram
4x VGA compatible controller [0300]: NVIDIA Corporation GP102 [TITAN X] [10de:1b00] (rev a1)
Starting 116G ram 16vcpus + 4 pci passthrough allocating memory stops after about half of the memory.
When upgrading from kernel 4.13.0 to 4.15.0 starting a vm takes a long time.
I tested kernel :
