Jun 1, 2026June 2026: Focused on improving operational clarity and reliability of host evacuation in xen-api. Delivered a targeted bug fix that clarifies the root cause when evacuation is blocked by unprotected VMs. Introduced a dedicated error HOST_EVACUATE_VM_NOT_HA_PROTECTED and ensured it reports the VM reference with actionable guidance. This change resolves a long-standing confusion where HOST_NOT_ENOUGH_FREE_MEMORY was misleading and aligns with HA planning behavior. Closes issue #4323. Commit 3b63bc07a7ee8e5b021d30341590c29220139b2e implements this change.
