 # CPU Low latency setup:
-#

 # A cpu is set to low latency when:
 # 1) host is set to subfunction=lowlatency in platform.conf and
 # 2) domain has dedicated pinning
 #
 # example of <cputune> section when domain has dedicated pinning:
-# <cputune> 
-#     <vcpupin vcpu='0' cpuset='5'/> 
-#     <vcpupin vcpu='1' cpuset='6'/> 
-#     <vcpupin vcpu='2' cpuset='7'/>

+#     <vcpupin vcpu='2' cpuset='7'/>
+#     <emulatorpin cpuset='5'/>
