is there a technical term for the host that should be used to run a specific M under normal circumstances? i.e. unless the host failed, the host that the VM should be run from..

and where within vcenter appliance can you see which VM's are running on which hosts?

You would usually have a Cluster of Hosts, and the VMs would be distributed across the cluster. So a VM could be running on any host.

The virtual machine view, shows which VMs are on which hosts, when connected to vCenter Server (appliance or Windows Server)

You can check it in the vSphere client>VM/s summary
vm summaryThe host that says localhost.localdomain is the host.

there's nothing called defau;t host for Vm. It can run on any host.

VMs on Hosts
these are VMs, I've removed the names, running across 6 hosts in a cluster.

but we have discussed before, for example, its common sense and best practice to house domain controllers or exchange servers on different hosts, so somewhere you must be able to chose which host which VM goes on?

You can "lock" VMs to certain hosts if you want to. Using Affinity Rules.

Or you can use Anti-Affinity rules to keep Domain Controllers apart, so they will never be on the same host.

But as for knowing which VM on which Host, does it really matter, if ALL the hosts are the same specification , e.g. CPU and Memory.

As long as the VMs are up, and Service is Up, it does not matter which VMs are on which hosts, and provided rules are in place to keep servers apart, reduces the single point of failure.

You would select your Cluster > Right Click - Edit Settings - VMware vSphere DRS - Rules.

(if you have DRS). Otherwise it's manual placement.

This is a Licensed Option, in Enterprise and Enterprise Plus, which has

DRS will only work with Enterprise license and above.
And no RVtools will not give that info.

DRS is a Licensed option with VMware vSphere.

This is a Licensed Option, in Enterprise and Enterprise Plus.

Do you have Enterprise and Enterprise Plus?

Check you License, Home > Administration > Licensing

in VMware vSphere Client.

Its only for bigger environment for load balancing across the hosts.
