Subject: [PATCH 0/2] Enable notify VM exit
Date: Thu, 10 Mar 2022 17:02:03 +0800 [thread overview]
Message-ID: <20220310090205.10645-1-chenyi.qiang@intel.com> (raw)
Notify VM exit is introduced to mitigate the potential DOS attach from
malicious VM. This series is the userspace part to enable this feature
through a new KVM capability KVM_CAP_X86_NOTIFY_VMEXIT. The
corresponding KVM patch series is available at
https://lore.kernel.org/lkml/20220310084001.10235-1-chenyi.qiang@intel.com/
