Hardware is Odroid XU4 with Exynos with 4.9.61+ Tested with Debian Stretch (9) or Buster (10). Without KVM it is running fine but slow. I'm operating Debian Jessie with qemu 2.1 for a long time with KVM virtualization working flawlessly. When I upgraded to Stretch I ran into the trouble described before. I tried Debian Stretch and Buster with all Kernels provided by the Board manufacturer (Hardkernel). It seems to be related to the feature introduced in Version 2.6: https://wiki.qemu.org/ChangeLog/2.6 - Support for a separate EL3 address space KVM is enabled, so I assume the adress space index asidx to be causing the assert to fail. dmesg | grep -i KVM [ 0.741714] kvm [1]: 8-bit VMID [ 0.741721] kvm [1]: IDMAP page: 40201000 [ 0.741729] kvm [1]: HYP VA range: c0000000:ffffffff [ 0.742543] kvm [1]: Hyp mode initialized successfully [ 0.742600] kvm [1]: vgic-v2@10484000 [ 0.742924] kvm [1]: vgic interrupt IRQ16 [ 0.742943] kvm [1]: virtual timer IRQ60 Full command line is: qemu-system-arm -M vexpress-a15 -smp 2 -m 512 -cpu host -enable-kvm -kern= el vmlinuz -initrd initrd.gz -dtb vexpress-v2p-ca15-tc1.dtb -device virtio-= blk-device,drive=3Dinst-blk -drive file=3DPATHTOFILE,id=3Dinst-blk,if=3Dnon= e,format=3Draw -append "vga=3Dnormal rw console=3DttyAMA0" -nographic Is there anything to do to understand, if this is a hardware related failure or probably just a missing parameter?
