 It is possible to throttle the aggregate bandwidth or operations
 of multiple virtio-blk devices using a `rate_limit_group`. virtio-blk devices may be
 dynamically added and removed from a `rate_limit_group`. The following example
 demonstrates how to throttle the aggregate bandwidth of two disks to 10 MiB/s.

 ```
 --disk path=disk0.raw,rate_limit_group=group0 \
        path=disk1.raw,rate_limit_group=group0 \

+# How to build and test Cloud Hypervisor on riscv64
+
+This document introduces how to build and test Cloud Hypervisor on `riscv64`.
+All instructions here are tested with Ubuntu 24.04.2 as the host OS.
+
+## Hardware requirements
+
+- riscv64 servers (recommended) or development boards equipped with the AIA
+(Advance Interrupt Architecture) interrupt controller.
+
+## Getting started
+
+We create a folder to build and run Cloud Hypervisor at `$HOME/cloud-hypervisor`
+
+```console
+export CLOUDH=$HOME/cloud-hypervisor
+mkdir $CLOUDH
+```
+
+## Prerequisites
+
+You need to install some prerequisite packages to build and test Cloud Hypervisor.
+
+### Tools
+
+```console
+# Install rust tool chain
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+# Install the tools used for building guest kernel, EDK2 and converting guest disk
+sudo apt-get update
+sudo apt-get install git build-essential m4 bison flex uuid-dev qemu-utils
+```
+
+### Building Cloud Hypervisor
+
+```console
+pushd $CLOUDH
+git clone https://github.com/cloud-hypervisor/cloud-hypervisor.git
+cd cloud-hypervisor
+cargo build
+popd
+```
+
+### Disk image
+
+Download the Ubuntu cloud image and convert the image type.
+
+```console
+pushd $CLOUDH
+wget https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-riscv64.img
+qemu-img convert -p -f qcow2 -O raw jammy-server-cloudimg-riscv64.img jammy-server-cloudimg-riscv64.raw
+popd
+```
+
+## Direct-kernel booting
+
+### Building kernel
+
+```console
+pushd $CLOUDH
+git clone --depth 1 "https://github.com/cloud-hypervisor/linux.git" -b ch-6.12.8
+cd linux
+make ch_defconfig
+make -j `nproc`
+popd
+```
+
+### Booting the guest VM
+
+```console
+pushd $CLOUDH
+sudo $CLOUDH/cloud-hypervisor/target/debug/cloud-hypervisor \
+           --kernel $CLOUDH/linux/arch/riscv64/boot/Image \
+           --disk path=jammy-server-cloudimg-riscv64.raw \
+           --cmdline "console=hvc0 root=/dev/vda rw" \
+           --cpus boot=1 \
+           --memory size=1024M \
+           --seccomp false \
+           --log-file boot.log -vv
+popd
+```
+
+## Known limitations
+
+- Direct kernel boot only
+- `64-bit Linux` guest OS only
+- For more details, see
+  [here](https://github.com/cloud-hypervisor/cloud-hypervisor/issues/6978).

+
+### Experimental `riscv64` Architecture Support
+
+Cloud Hypervisor now has experimental `riscv64` architecture
+support. Details can be found from the [riscv
+documentation](docs/riscv.md).
+
+### Alphabetically Sorted CLI Options
+
+To improve the readability of CLI options, the output of the `--help`
+now is alphabetically sorted. (#6988)
+
+### Improved Downtime of VM Live Migration
+
+The downtime of VM live migration is reduced via delaying some of the
+tearing down process of the source VM after the destination VM is up and
+running. (#6987)
+
+### Notable Bug Fixes
+
+* Fix seccomp filters related to http-api thread (#6967)
+* Handle cross-page access in the emulator for mshv (#6968)

 ### Improved live migration support
 
 The live migration support inside Cloud Hypervisor has been improved with the addition of the tracking of dirty pages written by the VMM to complement the tracking of dirty pages made by the guest itself. Further the internal state of the VMM now is versioned which allows the safe migration of VMs from one version of the VMM to a newer one. However further testing is required so this should be done with care. See the [live migration documentation](docs/live_migration.md) for more details.
