Subject: [PATCH] Introduce EXPAND_CPU_FEATURES flag for domain capabilities
|
||||
|
||||
The new VIR_CONNECT_GET_DOMAIN_CAPABILITIES_EXPAND_CPU_FEATURES flag for
|
||||
virConnectGetDomainCapabilities can be used to request the host-model
|
||||
CPU definition to include all supported features (normally only extra
|
||||
features relative to the selected CPU model are listed).
