I can reproduce it on Fedora 21 with: rmmod kvm-intel modprobe kvm-intel nested=1 virtme-configkernel --defconfig make -j12 bzImage virtme-run --pwd --kimg arch/x86/boot/bzImage --qemu-opts -m 1024 -smp 3 [wait for L1 to boot] virtme-run --kimg arch/x86/boot/bzImage This is with virtme from here: https://git.kernel.org/cgit/utils/kernel/virtme/virtme.git/ I can try to be more helpful in the morning. --Andy > > Tiejun > >> KVM internal error.
