Hi, I will add riscv32 support and send v2 series. But I don't test completely, because it need time to build riscv32 QEMU and its dependent libraries. Anyway, I will continue to build and test riscv32 QEMU. By the way, I had a problem with start riscv64 vm at latest kvm-riscv version. lastest version: tcg qemu: https://github.com/qemu/qemu linux: https://github.com/kvm-riscv/linux opensbi: https://github.com/riscv/opensbi kvmtool: https://github.com/kvm-riscv/kvmtool when start vm with kvmtools or this qemu series, I received kernel panic. Do you have this problem ?
