Default host-naming behavior when you add a VM to an environment
When you add duplicate copies of a VM to an environment, any duplicate hostname is changed to prevent conflict.
The new hostname is host-X, where X is the number of the first VM with a changed hostname:
| VM | Name |
|---|---|
| VM 1 | biz–host |
| First copy of VM 1 | host-1 |
| Second copy of VM 1 | host-2 |
| Third copy of VM 1 | host-3 |
| Fourth copy of VM 1 | host-4 |
| Fifth copy of VM 1 | host-5 |
When you add duplicate copies of multiple VMs, the hostname sequence continues:
| VM | Name |
|---|---|
| VM 1 | web-host |
| VM 2 | db-host |
| First copy of VM 1 | host-1 |
| First copy of VM 2 | host-2 |
| Second copy of VM 1 | host-3 |
| Second copy of VM 2 | host-4 |
If you add a new VM with a hostname that doesn’t conflict with any hostname in the environment, the new VM hostname isn’t changed:
| VM | Name |
|---|---|
| VM 1 | other-host |
| First copy of VM 1 | host-1 |
| VM 2 | another-host |
| Second copy of VM 1 | host-2 |
| Third copy of VM 1 | host-3 |
| Second Copy of VM 2 | host-4 |
If you delete one or more VMs from an environment, the hostname numbering sequence fills in that “gap” before continuing the sequence:
| VM | Name |
|---|---|
| VM 1 | other-host |
| Second copy of VM 1 | host-2 |
| Third copy of VM 1 | host-3 |
| Fourth copy of VM 1 | host-1 |
| Fifth copy of VM 1 | host-4 |
