here is my command line: TCG: sudo /home/augere/UPSTREAM/qemu/aarch64-softmmu/qemu-system-aarch64 -M virt-2.12,gic-version=3,iommu=smmuv3 \ -cpu cortex-a57 -smp 8 -m 4096 -display none -machine accel=tcg \ -serial tcp:localhost:4444,server -trace events=/home/augere/TEST/QEMU/hw-arm-smmu \ -qmp unix:/home/augere/TEST/QEMU/qmp-sock,server,nowait \ -device virtio-blk-pci,bus=pcie.0,scsi=off,drive=drv0,id=drv0,bootindex=1,iommu_platform,disable-modern=off,disable-legacy=on,werror=stop,rerror=stop \ -drive file=/home/augere/VM/IMAGES/vm0.qcow2,format=qcow2,if=none,id=drv0 \ -device virtio-net-pci,bus=pcie.0,netdev=nic0,mac=6a:f5:10:b1:3d:d2,iommu_platform,disable-modern=off,disable-legacy=on \ -netdev tap,id=nic0,script=/home/augere/TEST/SCRIPTS/qemu-ifup,downscript=/home/augere/TEST/SCRIPTS/qemu-ifdown \ -net none or with acceleration: sudo /home/augere/UPSTREAM/qemu/aarch64-softmmu/qemu-system-aarch64 -M virt-2.12,gic-version=3,iommu=smmuv3 -cpu host -smp 8 -m 4096 -display none --enable-kvm ../.. I reproduce with both, 100% of the cases. Trying to reproduce with intel iommu as well. Thanks Eric
