Demo Linux virtual appliance
We provide a fully functional installation of a Demo Linux Virtual Appliance, based on a CentOS 7.5 distribution.
The appliance is available for download, in a single
xva file from the Citrix Hypervisor Download page.
xva file can be quickly imported into XenCenter to create a fully working Linux Virtual Machine. No additional configuration steps are required.
The Demo Linux Virtual Appliance allows you to deploy a VM quickly and simply. You can use this appliance to test Citrix Hypervisor product features such as live migration, Dynamic Memory Control, and high availability. Citrix VM Tools are preinstalled in the Demo Linux Virtual Appliance. The appliance also includes pre-configured networking connectivity and a web server for test purposes.
Do not use the Demo Linux Virtual Appliance for running production workloads.

When you first start the VM, you are prompted to enter a root password. The IP address of the VM is then displayed. Ensure that you record the IP address, as it is useful for test purposes.
This section lists some useful tests to carry out to ensure that your Demo Linux Virtual Appliance is correctly configured.
Test that you have external networking connectivity.
Log in to the VM from the XenCenter console. Run this comment to send ping packets to Google and back:
ping -c 10 google.com
Other installed networking tools include ifconfig, netstat, and tracepath.
Using the IP address displayed on VM boot, test that you can ping the VM from an external computer.
Test that the web server is configured.
In a web browser, enter the VM IP address. The “Demonstration Linux Virtual Machine” page opens. This page displays simple information about the VM mounted disks, their size, location, and usage.
You can also use the webpage to mount a disk.
Mount a disk using the Demonstration Linux Virtual Machine webpage
In XenCenter, add a virtual disk to your VM. Select the VM in the Resources pane, open the Storage tab, and then click Add.
Enter the name of the new virtual disk and, optionally, a description.
Enter the size of the new virtual disk.
Ensure that the storage repository where the virtual disk is stored has sufficient space for the new virtual disk.
Select the SR where the new virtual disk is stored.
Click Create to add the new virtual disk and close the dialog box.
Click the Console tab, and user your normal tools to partition and format the disk as required.
Refresh the Demonstration Linux Virtual Machine webpage, the new disk is displayed.
Click Mount. This action mounts the disk, and filesystem information is displayed.
For more information on adding virtual disks, see the XenCenter documentation.
