Limitations
There are issues running TNSR on Azure which can lead to problems when communicating using public IP addresses
between multiple TNSR instances all running on Azure.
When a batch of packets is read using the DPDK netvsc PMD, the driver occasionally populates an invalid buffer
address. Attempting to process that packet results in a segmentation fault in the dataplane (VPP).
This issue only occurs when sending packets to a public IP address that is associated with a NIC that is managed by
TNSR on Azure. Sending to the NIC private address from another VM in the same vnet does not result in a crash.
Sending to the public IP address from a host outside of Azure also does not result in a crash.
The issue is being investigated by Microsoft.
1.3 Virtual Machines
A TNSR software Bare Metal Image is available and will run in most virtual x86 environments.
• VMware - vSphere/ESXi 6.0 and later, running VMXNET3 virtual network adapters.
Note: VMware VMXNET3 interfaces are not currently compatible with VRRP. The VMXNET3 interface
driver does not support setting virtual MAC addresses, which is required by VRRP.
Warning:
Secure boot is not compatible with TNSR, it prevents interfaces from being added to the data-
plane when it is enabled. If a VMware virtual machine has
Firmware
set to EFI under
VM Options
>
Boot
Options
, then
Enable UEFI secure boot
must be unchecked .

KVM
- Kernel Virtual Machine on Linux.
• virtio-net - Paravirtualized network adapter used by other hypervisors such as QEMU and VirtualBox.
1.3.1 Using TNSR on KVM
TNSR can be run on a Linux Kernel Virtual Machine (KVM) hypervisor host. The advice on this page is specifically
geared toward KVM managed by
libvirt .
