dmesg after second launch + 4.17-rc1

Same problem with the Kernel 4.17-rc1. To be sure, i need to install this
kernel only on the Host, no need to install it on the Linux Guest ?

I use my own kernel 4.17 so maybe IOMMU/VFIO options are missing :

odelpasso@debian-desktop:~/Bureau$ cat /boot/config-4.17.0-rc1 | grep VFIO
CONFIG_VFIO_IOMMU_TYPE1=m
CONFIG_VFIO_VIRQFD=m
CONFIG_VFIO=m
# CONFIG_VFIO_NOIOMMU is not set
CONFIG_VFIO_PCI=m
CONFIG_VFIO_PCI_VGA=y
CONFIG_VFIO_PCI_MMAP=y
CONFIG_VFIO_PCI_INTX=y
CONFIG_VFIO_PCI_IGD=y
# CONFIG_VFIO_MDEV is not set
CONFIG_KVM_VFIO=y

odelpasso@debian-desktop:~/Bureau$ cat /boot/config-4.17.0-rc1 | grep IOMMU
# CONFIG_GART_IOMMU is not set
# CONFIG_CALGARY_IOMMU is not set
CONFIG_IOMMU_HELPER=y
CONFIG_VFIO_IOMMU_TYPE1=m
# CONFIG_VFIO_NOIOMMU is not set
CONFIG_IOMMU_API=y
CONFIG_IOMMU_SUPPORT=y
# Generic IOMMU Pagetable Support
CONFIG_IOMMU_IOVA=y
CONFIG_AMD_IOMMU=y
CONFIG_AMD_IOMMU_V2=y
# CONFIG_INTEL_IOMMU is not set
