Live migration from VMware to OpenStack
summary
Claims a non‑intrusive live migration from VMware to OpenStack that preserves running services by combining agentless disk read via Watson Disk Developer Kit SDK, CBT (Changed Block Tracking) increments, and a Windows silent snapshot to flush OS cache before final sync. A proxy migration VM uses VDDK to copy volumes into OpenStack, preserves IP/MAC via cloud-init mac/ip injection, offers driver choices (IDE/e1000), and stops when incremental delta falls below a threshold; platform reports 500‑node, 20,000‑VM scale and 2,000 concurrent ops.
