+Snapshot/Restore and Live Migration Improvements # An offloaded snapshot/restore daemon has been introduced, allowing snapshot and restore to be carried out by an external process. The live migration protocol has been extended so page faults can be serviced from the source. This enables postcopy for remote live migration and on-demand paging for the offload daemon, both built on userfaultfd, bringing the offload daemon to parity with the internal snapshot/restore implementation (#8403, #8264, #8556).</description></item><item><title>Cloud Hypervisor v52.0 Released!</title><link>https://www.cloudhypervisor.org/blog/cloud-hypervisor-v52.0-released/</link><pubDate>Thu, 14 May 2026 21:58:11 +0000</pubDate><guid>https://www.cloudhypervisor.org/blog/cloud-hypervisor-v52.0-released/</guid><description>This release has been tracked in v52.0 group of our roadmap project.
 Security Fixes # This release fixes a use-after-free vulnerability in the virtio-block async I/O completion path (#8220). Details can be found in GHSA-f47p-p25q-83rh (CVE-2026-45782).
 Confidential VM Support: KVM SEV-SNP # AMD SEV-SNP confidential VMs can now be launched on KVM in addition to MSHV. Cloud Hypervisor uses guest_memfd to back private memory and loads an IGVM-packaged firmware (e.g. Oak stage0) to bring up an SEV-SNP guest on real hardware (#7942).</description></item><item><title>Cloud Hypervisor v51.2 Released!</title><link>https://www.cloudhypervisor.org/blog/cloud-hypervisor-v51.2-released/</link><pubDate>Thu, 14 May 2026 21:57:08 +0000</pubDate><guid>https://www.cloudhypervisor.org/blog/cloud-hypervisor-v51.2-released/</guid><description>This is a point release containing security fixes to a use-after-free vulnerability in the virtio-block async I/O completion path (#8220).

 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)

 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)
