Hi experts,

Q1:What's the different for "dom0_max_vcpus=4 dom0_vcpus_pin" and  "dom0_max_vcpus=4" ?
which will get better performance

Q2: dom0_max_vcpus=4 means "core0-3 will be just used by dom0" or means "4 cores(not dedicate cores) will be used by dom0, eg: core2-5 or core3-6?

Q3.what does mean "nosmp" , xen, dom0,domU, will just use one core????if so, can we specify the use different core. eg: dom0=core2 domU=core3? xen will use just one core?
