How to keep 2 vm's on different hosts

[jllotz1]

I have two critical vm's and want to make sure they stay on different hosts at all times. How can I do that?

We have 5 IBM hosts in an ESX 3.5 cluster. Thanks.

create a DRS rule to "seperate virtual machines".

edit settings of your cluster, VMware DRSRulesAdd

If you have DRS - then create rule to separate them, it will be done automatically.

If not - there no simple way. You can check where VMs are placed manually, or you can prevent them to migrate from host to host by binding VM to host. For example, create dummy 1MB vmdk on local storage.

Thanks everyone for your quick response. I have created an anti-affinity rule and it is working as expected.
