I have started a virtual machine on amd64 with:
/usr/bin/qemu-system-riscv64 -machine virt -nographic -m 8192 -smp 8 -bios /usr/lib/riscv64-linux-gnu/opensbi/generic/fw_jump.bin -kernel /usr/lib/u-boot/qemu-riscv64_smode/uboot.elf -device virtio-net-device,netdev=eth0 -netdev user,id=eth0 -device virtio-rng-pci -drive file=ubuntu-23.10-preinstalled-server-riscv64.img,format=raw,if=virtio
That VM provides the hypervisor extension needed for KVM. I try to launch a nested VM with:
qemu-system-riscv64 -machine virt -nographic -m 768 -smp 4 -bios /usr/lib/riscv64-linux-gnu/opensbi/generic/fw_jump.bin -kernel /usr/lib/u-boot/qemu-riscv64_smode/uboot.elf -device virtio-net-device,netdev=eth0 -netdev user,id=eth0 -device virtio-rng-pci -drive file=ubuntu-23.10-preinstalled-server-riscv64.img,format=raw,if=virtio -accel kvm -cpu host
This leads to a crash

_usr_bin_qemu-system-riscv64.1000.crash
The error only occurs when specifying -cpu host (which is enumerated with -cpu list).
Nested emulation was working on kinetic with -cpu host.
-bios must not be specified for the secondary VM running on KVM as kvm provides the SBI implementation.
