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 : linux-image-4.13.0-37 not affected linux-image-4.13.0-45 not affected linux-image-4.15.0-34 affected linux-image-4.15.0-42 affected
After disabling transparent_hugepage on 4.15 everything seems to work correctly.
