Live-migration support in FreeBSD and bhyve coming

FreeBSD's bhyve hypervisor now supports live virtual machine migration, allowing running VMs to move between hosts over TCP with minimal downtime through a pre-copy memory transfer phase followed by a brief pause for final state synchronization. The implementation, presented as a working prototype for FreeBSD 15.1, uses dirty-page tracking in the kernel and a migration protocol to enable enterprise virtualization capabilities like host maintenance and load balancing without significant service disruption. This development is critical for FreeBSD-based virtualization projects like Sylve and BoxyBSD that require reliable VM migration for practical cluster operations.
