However this can cause CPU to be made # part of the wrong node, (most likely to be node 0). This is because # VPHN is not enabled on KVM guests. # # With 2ea6263 ("powerpc/topology: Get topology for shared processors at # boot"), associativity is used to set to the wrong node. Hence KVM # guest topology is broken. # # For example : A 4 node KVM guest before would have reported. # # [root@localhost ~]# numactl -H # available: 4 nodes (0-3) # node 0 cpus: 0 1 2 3 # node 0 size: 1746 MB #
