Install a NetScaler VPX instance on Linux-KVM platform

Last published : Oct 01, 2026
To set up a NetScaler VPX for the Linux-KVM platform, you can use the graphical Virtual Machine Manager (Virtual Manager) application. If you prefer the Linux-KVM command line, you can use the virsh program.
The host Linux operating system must be installed on suitable hardware by using virtualization tools such as KVM Module and QEMU. The number of virtual machines (VMs) that can be deployed on the hypervisor depends on the application requirement and the chosen hardware.
After you provision a NetScaler VPX instance, you can add more interfaces.

Limitations and usage guidelines

General recommendations

To avoid unpredictable behavior, apply the following recommendations:
  • Do not change the MTU of the VNet interface associated with the VPX VM. Shut down the VPX VM before modifying any configuration parameters, such as Interface modes or CPU.
  • Do not force a shutdown of the VPX VM. That is, do not use the Force off command.
  • Any configurations done on the host Linux might or might not be persistent, depending on your Linux distribution settings. You can choose to make these configurations persistent to ensure consistent behavior across reboots of host Linux operating system.
  • The NetScaler package has to be unique for each of the NetScaler VPX instance provisioned.

Limitations

  • Live migration of a VPX instance that runs on KVM is not supported.
