How to segregate one ESXi host in a DRS cluster ?
Hi all,
I've got existing VMware DRS cluster of 8 ESXi hosts and also network configured with distributed vSwitch.
How can I assign one ESXi host only to a VM that I selected to Vmotion ?
Does VMware Vmotion also work when I exit the sea cluster for one host only ?
What's the impact to the running VM ?
Thanks,

No I want to isolate one particular host so that I can test a VM with CPU ready issue.
The test will prove that if the single big VM with multiple vCPU can run better if there is no other VM running on the ESXi host.
So the end game is to find the lower amount of vCPU without the CPU ready issue when running with multiple VM is the DRS cluster.

Move the Host out of the Cluster.
or define a new Cluster, which is what we have, a Production and Research and Development Cluster.

Hi Andrew,
Does it have to be a single host cluster or it can be just stand alone ?
How to move out one ESXi host only to the stand alone host configuration or new cluster ?
Does the VM network on the distributed vswitch also remains the same or lost when it exit the cluster ?

you can create a cluster with single host or just a single host outside the cluster
drag and drop the host outside the cluster.
vm networking is part of host and vcenter not the cluster

Ah I see, so when I just drag n drop the particular ESXi host, it will then become a stand alone ESXi host outside the DRS cluster I assume.
VMotion and svMotion will still be working on this single ESXi host.
steps:
1. Put the ESXi host into maintenance mode
2. Drag n Drop outside DRS cluster
3. exit maintenance mode
4. manually vMotion the VM to test.
is that correct steps ?

Thanks !
You only want to vMotion a VM to a particular host ?
if you have a cluster, all hosts will be available from within the cluster, to vMotion a VM to?
