# Step 4. Define Project Scenarios

At the **Scenario** step of the wizard, change parameters of the deployment project scenario. A deployment project scenario describes configuration of the hosts or VMs that must be added or evicted from the target container. One scenario can combine conditions for adding and evicting both hosts and VMs.

To change parameters of the deployment project scenario:

- Click **Add** and choose which object you want to add to the selected container:
  - [New VM](#new_vm)
  - [New Host](#new_host)
  - [Existing VM](#copy_vm)
  - [Existing Host](#copy_host)

- Click **Evict** and choose which object you want to evict from the selected container:
  - [Existing VM](#evict_vm)
  - [Existing Host](#evict_host)

- Click **Edit** to modify the selected scenario entry.
- Click **Delete** to delete the selected scenario entry.

After you configure deployment scenario parameters, click **Finish** to save the deployment project.

## Adding New VM {#new_vm}

To simulate a situation of adding new VMs to a host or cluster:

1. At the **Scenario** step of the wizard, click **Add** and select **New VM**.
2. In the **Add New VM** window, specify VM properties:

   - **Name** — VM name.
   - **Number of vCPUs** — the number of virtual CPU cores allocated to the VM.
   - **vCPU frequency** — each virtual CPU clock speed.
   - **Memory** — the amount of memory resources allocated to the VM.
   - **Disk capacity** — capacity of each virtual disk allocated to the VM.
   - **Number of disks** — the number of virtual disks allocated to the VM.
   - **Number of VMs** — the number of identical VMs to be added to the deployment project.

3. Click **Add**.

## Adding New Host {#new_host}

To simulate a situation of adding new hosts to a cluster:

1. At the **Scenario** step of the wizard, click **Add** and select **New Host**.
2. In the **Add New Host** window, specify host properties:

   - **Name** — the host name.
   - **Number of vCPUs** — the number of virtual CPU cores allocated to the host.
   - **vCPU frequency** — each virtual CPU clock speed.
   - **Memory** — the amount of memory resources allocated to the host.
   - **Number of hosts** — the number of identical hosts to be added to the deployment project.

3. Click **Add**.

## Adding Existing VM {#copy_vm}

To simulate a situation of adding copies of an existing VM to a host or cluster:

1. At the **Scenario** step of the wizard, click **Add** and select **Existing VM**.
2. In the **Add Existing VM** window, select a VM from the list and specify the number of VMs to be added.

   The VM selection scope includes all VMs in the selected container.

3. Click **Add**.

## Adding Existing Host {#copy_host}

To simulate a situation of adding copies of existing host to a cluster:

1. At the **Scenario** step of the wizard, click **Add** and select **Existing Host**.
2. In the **Add Existing Host** window, select a host from the list and specify the number of hosts to be added.

   The host selection scope includes all hosts in the selected container.

3. Click **Add**.

## Evicting Existing VM {#evict_vm}

To simulate a situation of evicting a VM from a host or cluster:

1. At the **Scenario** step of the wizard, click **Evict** and select **Existing VM**.
2. In the **Evict Existing VM** window, select a VM from the list.

   The VM selection scope includes all VMs in the selected container.

3. Click **Evict**.

## Evicting Existing Host {#evict_host}

To simulate a situation of evicting a host from a cluster:

1. At the **Scenario** step of the wizard, click **Evict** and select **Existing Host**.
2. In the **Evict Existing Host** window, select a host from the list.

   The host selection scope includes all hosts in the selected container.

3. Click **Evict**.
