query-dump-guest-memory-capability reported win-dmp on any x86 machine, whether or not the guest had published a Windows dump header. QEMU commit 1c0e259c5a35 tied it to the guest's vmcoreinfo note, but left the change invisible to introspection.
QEMU 11.1 marks the win-dmp member of DumpGuestMemoryFormat with an 'allowed-by-guest' feature. Detect it, so a caller picking a dump format can tell whether a reported win-dmp says anything about the guest. Signed-off-by: Denis V. Lunev <[email protected]> Reviewed-by: Daniel P.
