Hi,
I'm working on a tree-wide accelerator refactor and want
to run various configs to be sure I didn't broke anything.
QEMU theoretically supports running a riscv32 guest using
KVM on a riscv64 host, however the documentation I'm finding
only refers to riscv64 guests:
https://github.com/kvm-riscv/howto/wiki
So I wonder, is this a valid / supported config? If so,
do you mind helping me with pointing me to a guest image
and its command line?
Thanks,
Phil.

Currently, we only support running rv64 guest on rv64 host
and rv32 guest on rv32 host.
In the future, we might support running rv32 guest on rv64 host
but as of now we don't see a strong push for it.

Anup

Good news, less configs to test!
Thank you,
Phil.
