You can improve performance of VM-Series on
KVM by isolating the CPU resources of the guest VM to a single non-uniform
memory access (NUMA) node. On KVM, you can view the NUMA topology
The following example is from a two-node NUMA system:
View the NUMA topology. In the example below,
there are two NUMA nodes (sockets), each with a four-core CPU with
hyperthreading enabled. All the even-numbered CPU IDs belong to
one node and all the odd-numbered CPU IDs belong to the other node.
