What is VMware host affinity rule?

An affinity rule is a setting that establishes a relationship between two or more VMware virtual machines (VMs) and hosts. If two virtual machines communicate frequently and should share a host, the VMware admin can create a VM-VM affinity rule to keep them together.

What are the 3 affinity rules?

Three types of rules are available:

affinity rules – DRS will try to keep certain VMs together on the same host.
anti-affinity rules – DRS will try to keep certain VMs are not on the same host.
VM to host rules – specify whether VMs can or can’t be run on a host.

How do I disable affinity rule in VMware?

(Optional) To delete a compute policy, open the vSphere Web Client, click Policies and Profiles > Compute Policies to show each policy as a card. Click DELETE to delete a policy.

How do you determine affinity rule?

To check whether any enabled affinity rules are being violated and cannot be corrected by DRS, select the cluster’s DRS tab and click Faults. Any rule currently being violated has a corresponding fault on this page. Read the fault to determine why DRS is not able to satisfy the particular rule.

How do you turn off affinity rules?

The Default VMDK Affinity Rule This default rule can be disabled by editing the “Advanced Options” under “Storage DRS” settings of your datastore cluster. However, disabling the default VM affinity rule for all VMs is not the recommended option.

What is affinity and anti-affinity rule in VMware?

An affinity rule places a group of virtual machines on a specific host so that you can easily audit the usage of those virtual machines. An anti-affinity rule places a group of virtual machines across different hosts, which prevents all virtual machines from failing at once in the event that a single host fails.

What affinity rule will keep a VM on certain hosts?

An affinity rule specifies that the members of a selected virtual machine DRS group can or must run on the members of a specific host DRS group. An anti-affinity rule specifies that the members of a selected virtual machine DRS group cannot run on the members of a specific host DRS group.

How do I create a VM anti-affinity rule in VMware?

Browse to the datastore cluster in the vSphere Client. Click the Configure tab and click Configuration. Select VM/Host Rules. Click Add. Type a name for the rule. From the Type menu, select VM anti-affinity. Click Add. Click Select Virtual Machine. Select at least two virtual machines and click OK. Click OK to save the rule.

How do I create VM-host affinity rules?

You can create VM-Host affinity rules to specify whether or not the members of a selected virtual machine DRS group can run on the members of a specific host DRS group. Create the virtual machine and host DRS groups to which the VM-Host affinity rule applies. Browse to the cluster in the vSphere Client. Under Configuration, click VM/Host Rules.

What is the difference between VM-VM and VM-host affinity?

Unlike a VM-VM affinity rule, which specifies affinity (or anti-affinity) between individual virtual machines, a VM-Host affinity rule specifies an affinity relationship between a group of virtual machines and a group of hosts. There are ‘required’ rules (designated by “must”) and ‘preferential’ rules (designated by “should”.)

How do I create a VM/host rule in VMware?

From the Type drop down menu, select Virtual Machines to Hosts. Select the virtual machine DRS group and the host DRS group to which the rule applies. Select a specification for the rule.
