A personal host pool is a type of host pool that has personal desktops. Personal desktops have one-to-one mapping, which means a single user can only be assigned to a single personal desktop. Every time the user signs in, their user session is directed to their assigned personal desktop session host. This host pool type is ideal for customers with resource-intensive workloads because user experience and session performance will improve if there's only one session on the session host. Another benefit of this host pool type is that user activities, files, and settings persist on the virtual machine operating system (VM OS) disk after the user signs out.

Users must be assigned to a personal desktop to start their session. You can configure the assignment type of your personal desktop host pool to adjust your Azure Virtual Desktop environment to better suit your needs. In this topic, we'll show you how to configure automatic or direct assignment for your users.

Note

The instructions in this article only apply to personal desktop host pools, not pooled host pools, since users in pooled host pools aren't assigned to specific session hosts.

Prerequisites

If you're using either the Azure portal or PowerShell method, you'll need the following things:

A personal host pool with at least one session host.
An Azure account assigned the Desktop Virtualization Contributor role.
If you want to use Azure CLI or Azure PowerShell locally, see Use Azure CLI and Azure PowerShell with Azure Virtual Desktop to make sure you have the desktopvirtualization Azure CLI extension or the Az.DesktopVirtualization PowerShell module installed. Alternatively, use the Azure Cloud Shell.

If you're assigning desktops with PowerShell, you'll need to download and install the Azure Virtual Desktop PowerShell module if you haven't already.

Configure automatic assignment

Automatic assignment assigns users a personal desktop the first time they connect. It's the default assignment type for new personal desktop host pools you create in your Azure Virtual Desktop environment. Automatically assigning users doesn't require a specific session host.

To automatically assign users, first assign them to the personal desktop host pool so that they can see the desktop in their feed. When an assigned user launches the desktop in their feed, their user session will be load-balanced to an available session host if they haven't already connected to the host pool. You can still assign a user directly to a session host before they connect, even if the assignment type is set automatic.

To configure automatic assignment in the Azure portal:

Sign in to the Azure portal.
In the search bar, enter Azure Virtual Desktop and select the matching service entry.
Select Host pools, then select the personal host pool you want to configure automatic assignment.
Next, select Properties, then go to the Assignment drop-down menu and select Automatic.
Select Save.

Here's how to configure a host pool to automatically assign users to VMs using the Az.DesktopVirtualization PowerShell module.

Launch the Azure Cloud Shell in the Azure portal with the PowerShell terminal type, or run PowerShell on your local device.
1. If you're using Cloud Shell, make sure your Azure context is set to the subscription you want to use.
2. If you're using PowerShell locally, first Sign in with Azure PowerShell, then make sure your Azure context is set to the subscription you want to use.

Run the Update-AzWvdHostPool command in the following example to configure a host pool to automatically assign users to VMs. For more information about the parameters,see the az-desktopvirtualization-hostpool Azure CLI reference.
```
Update-AzWvdHostPool -ResourceGroupName $resourceGroupName -Name $hostPoolName -PersonalDesktopAssignmentType Automatic
```

Here's how to configure a host pool to automatically assign users to VMs using the az-desktopvirtualization-hostpool-update command.

Launch the Azure Cloud Shell in the Azure portal with the Bash terminal type, or run Azure CLI on your local device.
1. If you're using Cloud Shell, make sure your Azure context is set to the subscription you want to use.
2. If you're using Azure CLI locally, first Sign in with Azure CLI, then make sure your Azure context is set to the subscription you want to use.

Run the command in the following example to configure a host pool to automatically assign users to VMs. For more information about the parameters, see the az-desktopvirtualization-hostpool Azure CLI reference.
```
az desktopvirtualization hostpool update \
    --resource-group $resourceGroupName \
    --name $hostPoolName \
    --personal-desktop-assignment-type Automatic
```

Configure direct assignment

Unlike automatic assignment, when you use direct assignment, you assign a specific personal desktop to a user first. You must assign the user to both the personal desktop host pool and a specific session host before they can connect to their personal desktop. If the user is only assigned to a host pool without a session host assignment, they won't be able to access resources and will see an error message that says No resources available.

To configure direct assignment in the Azure portal:

Sign in to the Azure portal.
In the search bar, type Azure Virtual Desktop and select the matching service entry.
Select Host pools, then select the personal host pool you want to configure automatic assignment.
Next, select Properties, then go to the Assignment drop-down menu and select Direct.
Select Save.

Here's how to configure a host pool to require direct assignment of users to session hosts using the Az.DesktopVirtualization PowerShell module.

Launch the Azure Cloud Shell in the Azure portal with the PowerShell terminal type, or run PowerShell on your local device.
1. If you're using Cloud Shell, make sure your Azure context is set to the subscription you want to use.
2. If you're using PowerShell locally, first Sign in with Azure PowerShell, then make sure your Azure context is set to the subscription you want to use.

Run the Update-AzWvdHostPool command in the following example to configure a host pool to require direct assignment. For more information about the parameters, see the Update-AzWvdHostPool reference.
```
Update-AzWvdHostPool -ResourceGroupName $resourceGroupName -Name $hostPoolName -PersonalDesktopAssignmentType Direct
```

Here's how to configure a host pool to automatically assign users to VMs using the az-desktopvirtualization-hostpool-update command.

Launch the Azure Cloud Shell in the Azure portal with the Bash terminal type, or run Azure CLI on your local device.
1. If you're using Cloud Shell, make sure your Azure context is set to the subscription you want to use.
2. If you're using Azure CLI locally, first Sign in with Azure CLI, then make sure your Azure context is set to the subscription you want to use.

Run the command in the following example to configure a host pool to automatically assign users to VMs. For more information about the parameters, see the az-desktopvirtualization-hostpool Azure CLI reference.
```
az desktopvirtualization hostpool update \
    --resource-group $resourceGroupName \
    --name $hostPoolName \
    --personal-desktop-assignment-type Direct
```

Give session hosts in a personal host pool a friendly name

You can give personal desktops you create friendly names to help users distinguish them in their feeds using PowerShell. The Azure portal or Azure CLI doesn't currently have a way to give session host friendly names.

Launch the Azure Cloud Shell in the Azure portal with the PowerShell terminal type, or run PowerShell on your local device.
- If you're using Cloud Shell, make sure your Azure context is set to the subscription you want to use.
- If you're using PowerShell locally, first Sign in with Azure PowerShell, then make sure your Azure context is set to the subscription you want to use.

Run the following command in PowerShell to add or change a session host's friendly name:

$parameters = @{
   HostPoolName = 'HostPoolName'
   Name = 'SessionHostName'
   ResourceGroupName = 'ResourceGroupName'
   FriendlyName = 'SessionHostFriendlyName'
}

Update-AzWvdSessionHost @parameters

To get the session host friendly name, run the following command in PowerShell:

$sessionHostParams = @{
   HostPoolName = 'HostPoolName'
   Name = 'SessionHostName'
   ResourceGroupName = 'ResourceGroupName'
}

Get-AzWvdSessionHost @sessionHostParams | FL Name, AssignedUser, FriendlyName

Next steps

Now that you've configured the personal desktop assignment type and given your session host a friendly name, you can sign in to an Azure Virtual Desktop client to test it as part of a user session. These articles will show you how to connect to a session using the client of your choice:
