Subject: [PATCH] Introduce
|
|
VIR_CONNECT_GET_DOMAIN_CAPABILITIES_SUPPORTED_CPU_FEATURES flag
|
|
|
|
Some CPU features may be enabled explicitly, but should not
|
|
automatically become part of a host-model CPU. Users can now request
|
|
such features to be shown in the host-model CPU in domain capabilities
|
|
by VIR_CONNECT_GET_DOMAIN_CAPABILITIES_SUPPORTED_CPU_FEATURES flag.
