4 Prepare Linux Machine for VDA Installation

4.1 Verify Network Configuration

It is recommended that the network is connected and properly configured correctly before

proceeding.

4.1.1 Assign Loopback Address to Hostname

To ensure that the DNS domain name and FQDN of the machine are reported back correctly,

change the following line of the /etc/hosts file to include the FQDN and hostname as the first two

entries:

127.0.0.1 hostname-fqdn hostname localhost localhost.localdomain

For example:

127.0.0.1 vda01.example.com vda01 localhost localhost.localdomain

Remove any other references to hostname-fqdn or hostname from other entries in the file.

4.1.2 Check Hostname

Check the hostname is set correctly:

hostname -f

This should return the machine's fully qualified domain name (FQDN).

4.1.3 Check Name Resolution and Service Reachability

Check that you can resolve the FQDN and ping the domain controller and XenDesktop Delivery

Controller:

nslookup domain-controller-fqdn

ping domain-controller-fqdn

nslookup delivery-controller-fqdn

ping delivery-controller-fqdn

4.2 Configure NTP Service

Maintaining accurate clock synchronization between the VDAs, XenDesktop Controllers and

domain controllers is crucial. Hosting the Linux VDA as a virtual machine can cause clock skew

problems. For this reason, maintaining time using a remote NTP service is preferred. Some changes

might be required to the default NTP settings.

1. Open System > Administration > Date & Time.

2. In the Date and Time tab, ensure Synchronize date and time over the network is

checked.

3. In the NTP Servers list, click Add.

4. Enter the hostname or IP address of a local NTP Server. This is typically the hostname of

the AD Domain Controller. The configuration tool will test for service reachability.

5. Optionally delete the other default NTP servers listed.

6. Click OK. This will restart the NTP daemon.
