v43.0 This release has been tracked in our [roadmap project](https://github.com/orgs/cloud-hypervisor/projects/6) as iteration v43.0. The following user visible changes have been made: Live Migration over TCP Connections ---- --------- ---- --- ----------- Support has been added to enable direct live migration from two hosts via TCP connections. This supplements the existing support for migrating over a UNIX socket which can then be tunnelled as desired. The documentation has been updated. (#6850) Notable Performance Improvements ------- ----------- ------------ The `VIRTIO_RING_F_INDIRECT_DESC` feature has been enabled for `virtio-block` devices. This significantly increases the throughput of the devices with a small negative impact on latency. (#6826) Notable Bug Fixes ------- --- ----- * Cloud Hypervisor now accepts VFIO devices that use I/O PCI BARs on non x86-64 architectures. Whether they function depends on the host PCI host bridge support - previously they would be rejected even if the driver did not use these BARs. (#6871) * Command line groups were adjusted to ensure that at least one payload parameter was provided if any other VM parameters provided.
