 # script to create cpusets to isolate CPU threads for KVM/libvirt VMs
 # requires 'cset'
 # available on Fedora through my COPR:
 #  - https://copr.fedorainfracloud.org/coprs/jlay/cpuset/
-# review notes regarding XML entries
+# review comments below regarding CPUs and XML entries
-
+#
 # this script:
 # - isolates host tasks from the VM CPUs
 # - applies some generic tweaks
 # - resets host isolation on VM shutdown
-
+#
-# Set the range of cores assigned to the windows VM
+# define the CPUs (cores/threads) to isolate for the VM
-# on an i9-7920x this is the first 8 cores and the corresponding hyperthreads
+VM_CORES='0-20,24-44'
-VM_CORES='0-7,12-19'
+# Tip: refer to 'virsh capabilities | grep siblings'
-
+# this will show CPU topology information for the host
-# based on the assignments of pinned CPUs in libvirt XML, eg:
+# allows one to pick optimal layout for the VM
 #
 # the pinned CPUs are definend like so in the VM libvirt XML:
 #    <vcpupin vcpu='0' cpuset='0'/>
-#    <vcpupin vcpu='1' cpuset='12'/>
+#    <vcpupin vcpu='1' cpuset='24'/>
 #    <vcpupin vcpu='2' cpuset='1'/>
 #    <vcpupin vcpu='3' cpuset='25'/>
 # [...]
-#    <vcpupin vcpu='14' cpuset='7'/>
+#     <emulatorpin cpuset='10-11'/>
-#    <vcpupin vcpu='15' cpuset='19'/>
+#
 # NOTE: the pinned emulator CPUs must be included in VM_CORES
 # probably any iothreads too
 #
 # example above is based on a threadripper 3960x:
 #  - one NUMA node
 #  - SMT enabled
 #
 # `lscpu -e` and `virsh capabilities` are helpful for determining valid pinning settings
 # on example system (i9 7920x), vCPUs 0-15 are pinned (alternating between) cores 0-7 and hyperthreads 12-19
