I use kvm openSUSE-42.2 as host and debian(jessie) as guest. Host PC has 2 NIC, one for openSUSE and other for debian(pci passthrough). Intel Corporation 82541PI Gigabit Ethernet assign to openSUSE. Intel Corporation 82579LM Gigabit Network assign to debian. Until kernel update to 4.4.70-18.9-default , debian recognize 82579LM and use it. After update, debian fail ifup eth0. debian # lsmod | grep e1000e e1000e 220778 0 ptp 17692 1 e1000e debian # modprobe -rv e1000e rmmod e1000e rmmod ptp rmmod pps_core debian # modprobe -v e1000e insmod /lib/modules/3.16.0-4-amd64/kernel/drivers/pps/pps_core.ko [ 138.684256] pps_core: LinuxPPS API ver. 1 registered [ 138.685331] pps_core: Software ver. 5.3.6 - Copyright 2005-2007 Rodolfo Giometti <giometti@linux.it> insmod /lib/modules/3.16.0-4-amd64/kernel/drivers/ptp/ptp.ko [ 138.688870] PTP clock support registered insmod /lib/modules/3.16.0-4-amd64/updates/drivers/net/ethernet/intel/e1000e/e1000e.ko [ 138.697285] e1000e: Intel(R) PRO/1000 Network Driver - 3.3.5.3-NAPI [ 138.698337] e1000e: Copyright(c) 1999 - 2016 Intel Corporation. debian # ip link 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 eth0 not found debian# ip link set eth0 up Cannot find device "eth0" At first, I thought that 82579LM Hardware problem. Then I did these command from openSUSE console. # virsh shutdown debian # systemctl stop libvirtd.service openSUSE# modprobe -r vfio_iommu_type1 rmmod vfio_iommu_type1 openSUSE # modprobe -rv vfio_pci rmmod vfio_pci rmmod vfio rmmod vfio_virqfd openSUSE # modprobe e1000e And, start YaST, setup e1000e (eth1) IPaddress. Then 82579LM work well. I think this is new kernel problem. How can I use pci passthrou correctly ?
