The current API allows us to report a single status, which we've defined as: Frozen: has a successor, treated as qmp_locked, may or may not be enabled. Locked: no successor, qmp_locked. may or may not be enabled. Disabled: Not frozen or locked, disabled. Active: Not frozen, locked, or disabled. The problem is that both "Frozen" and "Locked" mean nearly the same thing, and that both of them do not intuit whether they are recording guest writes or not. This patch deprecates that status field and introduces two orthogonal properties instead to replace it.
