## Anticollocation 

An anticollocation policy  indicates that the set of VMs must never be placed on the same host after relocation, as shown in Figure 3-6.

To set this policy, run the following commands: 

ksysmgr add collocation name vm=vmname1[,...]> ksysmgr modify collocation name policy=add|delete vm=vm1[,...] 

Example 3-58 shows the anticollocation policy policy_2 with the VMs rt12001  and rt12002 . 

# ksysmgr add anticollocation policy_2 vm=rt12001,rt11001 Anticollocation group policy_2 was created 

To list the anticollocation policies that are available, run the command ksysmgr query anticollocation , as shown in Example 3-59. 

# ksysmgr query anticollocation Name: policy_2 Type: anticollocation VMs: rt11001 rt12001 

Example 3-60 shows how to delete an anticollocation policy. 

# ksysmgr delete anticollocation policy_2 Anticollocation group policy_2 was removed
