Subject: [PATCH v4 13/15] pvh: Set online VCPU map to avail_vcpus
Date: Tue, 29 Nov 2016 10:33:20 -0500	[thread overview]
Message-ID: <1480433602-13290-14-git-send-email-boris.ostrovsky@oracle.com> (raw)
In-Reply-To: <1480433602-13290-1-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.
