2.2.6. Install as a VM using VMware¶
VMware basic deployment¶
Turbo Router is provided in the form of an OVA file. It is supported on:
ESX/ESXi 5.5 and later
vCenter Server 5.5 and later
Fusion 6.x
Workstation 10.x
Player 6.x
The image is configured to run with:
4 cores
8GB RAM
1 vmxnet3 NIC
If you wish to add other NICs, make sure they have the vmxnet3
virtualDev attribute, or Turbo Router will not be able to use them.
In order to boot your Turbo Router VM, import the OVA file in your VMware product.
The next step is to perform your first configuration.

Refer to VMware documentation for details on how to deploy VM images. For instance Deploying using vSphere 6.5, ESXi 6.5 or vCenter Server 6.5
VMware performance tuning¶
All ESXi version¶
Optimizations must be done in the hypervisor to achieve the best performance.
In the Virtual Hardware tab of the VM settings, set:
VM CPU
Reservationfield to its maximal valueVM CPU
Limitfield toUnlimited
In the VM Options tab, Advanced part of the VM settings, set:
sched.cpu.latencySensitivityto ‘High’: used to ensure pinning and exclusive affinity of all CPUs of a VNF
ESXi 6.5 and newer versions¶
Since ESXi 6.5, new tuning options are available to improve hypervisor’s performance. Before going further, all the settings described in the previous section must be applied.
In the VM Options tab, Advanced part of the VM settings, press the
Configuration Parameters button to set:
ethernetX.ctxPerDevto1(whereethernetXis the NIC which will be handled by the Turbo Router): each NIC configured with ctxPerDev will receive a TX thread in the hypervisor. It can be checked in theesxtopoutput. The ctxPerDev recommendation must be enabled for NICs that are expected to process an high packet load.sched.cpu.latencySensitivity.sysContextstonumerical value: system threads (TX and RX) are assigned exclusive physical CPU cores. The numerical value assigned tosched.cpu.latencySensitivity.sysContextsmust equal the number of active threads for the VNF. For example, if one receive thread exists and three TX threads have been set using thectxPerDevcommand, the value set must be 4. In this example, 4 physical CPU cores must be available and unreserved.
More details are available in VMware document regarding high performance setups.
esxtop reading¶
First, run esxtop command in the hypervisor’s console.
Here is the default esxtop screen (also accessible by hitting ‘c’):
