Citrix Netscaler VPX (or Citrix ADC VPX) has an ESXi and KVM distribution but there isn’t one for oVirt or RHEV/RHV (Red Hat Virtualization).
Nutanix, which uses AHV and is similar, has the following post to get Netscaler to work.
The key for oVirt/RHV is the image import and the serial port enablement. Following the steps below, you should have a working ADC/Netscaler VPX 12.x
- Download the KVM image from the Citrix Download site- You’ll need a trial license or a valid account with Citrix for the bits
- untar the tgz image and find the .qcow2 image -
-
Upload this as an image into RHV- 
-
Create a VM with 2 vCPU, a nic and attach the image you uploaded as IDE (not VirtIO)- 
-
IMPORTANT: select the option to add a virtual serial console to the VM- 
-
Booting may take a little bit as it tried to load the loader.conf but it should succeed.
