+Experimental fw_cfg Device Support # This feature enables passing configuration data and files, such as VM boot configurations (kernel, kernel cmdline, e820 memory map, and ACPI tables), from the host to the guest. (#7117)
+Experimental ivshmem Device Support # Support for inter-VM shared memory has been added. For more information, please refer to the ivshmem documentation. (#6703)
+Firmware Boot Support on riscv64 # In addition to direct kernel boot, firmware boot support has been added on riscv64 hosts.</description></item><item><title>Cloud Hypervisor v47.0 Released!</title><link>https://www.cloudhypervisor.org/blog/cloud-hypervisor-v47.0-released/</link><pubDate>Tue, 22 Jul 2025 22:48:05 +0000</pubDate><guid>https://www.cloudhypervisor.org/blog/cloud-hypervisor-v47.0-released/</guid><description>This release has been tracked in v47.0 group of our roadmap project.
 Block Device Error Reporting to the Guest # Instead of exiting on I/O errors, the virtio-block device now reports errors to the guest using VIRTIO_BLK_S_IOERR. It improves the user experience particularly when the guest rootfs is not backed by the affected block device. (#7107)
 Nice Error Messages on Exit # We now have the chain of errors being reported and printed nicely, when Cloud Hypervisor or ch-remote exits on errors.</description></item><item><title>Cloud Hypervisor v46.0 Released!</title><link>https://www.cloudhypervisor.org/blog/cloud-hypervisor-v46.0-released/</link><pubDate>Fri, 23 May 2025 22:07:00 +0000</pubDate><guid>https://www.cloudhypervisor.org/blog/cloud-hypervisor-v46.0-released/</guid><description>This release has been tracked in v46.0 group of our roadmap project.
 File-level Locking Support with --disk # Now file-level locking is enforced for disk images, provided by users with --disk. This ensures that only a single Cloud Hypervisor instance can obtain write access to a given disk image at any time, preventing misconfiguration and avoiding potential data corruption. (#6974)
