In the “Host-based failover clustering and migration for Exchange“ section of its Exchange 2013 virtualization whitepaper, Microsoft defined the following strict criteria for its support of VM “portability” for Exchange workloads: We are not aware of any documented incidents of “breakage” attributable to vMotion operations on these workloads, or even for Lync. The VMware’s “portability” feature is vMotion, a feature that has been in long use for clustered critical applications like Microsoft Exchange Server (DAG) and Microsoft SQL Server (MSCS or AlwaysOn). On the fourth point where the writers have stated that VM portability “breaks the inherent availability functionality in Lync Server pools”, we are unaware of the “breakage” alluded to in the document. Virtualizing Microsoft Lync Server – Let's Clear up the Confusion | Virtualize Business Critical App. Pertaining to your original problem I noticed this article. If not then my best option is going to be a section in the operational guide that identifies these machines as not valid candidates for vMotion (in conjunction with disabling DRS for those VMs) So my question is, that given the crazy number of advanced settings that exist, I was wondering whether there is a virtual machine advanced setting that disables vMotion regardless of DRS rules or administrator actions. If you power the VM off and migrate it (which you can do) to an alternate host the moment you try to power the VM on a lovely message is displayed saying that it would then violate the DRS rule.

If I create a DRS vm-to-host affinity rule it does as you say prevent both DRS vMotions and manual vMotions but it has a side effect that if you needed to perform maintenance on the host that you can't migrate the VM off the host whilst powered on. I am already going to be setting DRS to be disabled to prevent any automated vMotions but this doesn't prevent an administrator performing a manual migration. Unfortunately neither fully solves my problem! If it is useful, plz award points as appropriate Even though if you disable DRS on cluster or that VM this rule still holds good.Īnother way is to disable DRS/HA on that VM as specified by Mustafa. In all these cases VMs can not be vMotioned to other host.Ģ. VM-Host affinity rule is respected by DRS/HA/DPM & manual intervention.

Web client way: How to create VM to Host affinity rules using the webclient - ġ. (repeat the same with every pair of VM group & host group). Create VM-Host affinity must rule by associating appropriate VMgroup and host group. Create host group with only host on which you need to keep these VMs (If there are multiple host, then you need to create multiple host groups )ģ. (If you want to keep some VMs on some other hosts, you need to create multiple VM groups)Ģ. Create VM group with VMs those you do not want to vMotion. Simple way is to create VM-Host affinity MUST rule.ġ. There is NO any advanced setting to do the same.
