Subject: [PATCH v8 46/81] KVM: introspection: add KVMI_VM_CONTROL_EVENTS
Date: Mon, 30 Mar 2020 13:12:33 +0300 [thread overview]
Message-ID: <20200330101308.21702-47-alazar@bitdefender.com> (raw)
In-Reply-To: <20200330101308.21702-1-alazar@bitdefender.com>
With this command the introspection tool enables/disables VM events
(ie. KVMI_EVENT_UNHOOK).
By default, all events are disabled.
Signed-off-by: Adalbert Lazăr <alazar@bitdefender.com>
