Subject: [PATCH v6 10/12] pvh: Set online VCPU map to avail_vcpus
Date: Tue, 3 Jan 2017 09:04:14 -0500 [thread overview]
Message-ID: <1483452256-2879-11-git-send-email-boris.ostrovsky@oracle.com> (raw)
In-Reply-To: <1483452256-2879-1-git-send-email-boris.ostrovsky@oracle.com>
ACPI builder marks VCPUS set in vcpu_online map as enabled in MADT.
With ACPI-based CPU hotplug we only want VCPUs that are started by
the guest to be marked as such. Remaining VCPUs will be set to
"enable" by AML code during hotplug.
