Thanks for the draft and overall LGTM too. Small correction please, VMWare -> VMware. Also shall we call this feature “Reconciliation of VM and Volume Copy/Migrate operations for KVM agent” as “Introduced Reconciliation Framework with support for VM and Volume Copy/Migrate operations for KVM agent ”
