Pull request overview
Adds administrator documentation for an optimized VMware-to-KVM migration path using virt-v2v “vpx” mode with VMware VDDK, explaining prerequisites and host/agent configuration needed to enable block-streaming conversions (avoiding OVF export).
Changes:
- Document VDDK-based streaming workflow vs. the existing OVF-based conversion flow.
- Add KVM host preparation steps (packages, libguestfs backend, VDDK install, EL9 symlink).
- Document relevant CloudStack agent properties for VDDK-based conversion and operational recommendations.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

if "direct" is must for VDDK to work, should we avoid this config?

CloudStack supports an optimized VMware-to-KVM migration path using virt-v2v in vpx input mode combined with
VMware's Virtual Disk Development Kit (VDDK). This method eliminates the OVF export phase entirely and streams
disk blocks directly from the source hypervisor into the conversion pipeline, resulting in significantly faster
migration times.
