# CPU topology
|
|
# The product of the values of all parameters must equal the maximum number
|
|
# of vcpu:
|
|
# sockets * dies * cores * threads = max_vcpus
|
|
# dies is optional and equals 1 by default.
|
|
#
|
|
# If you need a complex topology, you will have to sacrifice the ability to
|
|
# hotplug vCPUS. You will need to set 'max_vcpus' to equal 'vcpus'. To apply
|
|
# the changes you will need to perform a power reset or manually shutdown
|
|
# and start instance (not reboot or reset).
|
|
#
|
|
# By default, the number of sockets will be set to the number of vCPUS. You
|
|
# may want to use a single socket without sacrificing the vCPUS hotplug, so
|
|
# you can set the following values:
|
|
#
|
|
# topology:
|
|
# sockets: 1
|
|
# cores: 4
|
|
# threads: 1
|
|
#
|
|
# Note that the value of 'cores' must be equal to 'max_vcpus'.
