After the desired VF comes into focus, click Finish. Scope This tutorial does not focus on performance. However, the connection performance varies by a factor of depending on which host device model is selected. For more complete information about compiler optimizations, see our Optimization Notice. Select Network as the type of device. Additional Findings In every configuration, the test VM was able to communicate with both the host and with the external traffic generator, and the VM was able to continue communicating with the external traffic generator even when the host PF had no IP address assigned to it as long as the PF link state on the host remained up.

Otherwise, newer versions would have been used.

Network Configuration The test setup included two physical servers—net2s22c05 and net2s18c03—and one VM—sr-iov-vf-testvm—that was hosted on net2s22c When evaluating the advantages and disadvantages of each insertion method, I looked at the following:.

There are a few downloads associated with this tutorial that you can get from github.

Operating System Ubuntu The virtual network created in step 1 appears in the list. Add a hostdev tag to the VM.

However, the connection performance varies by a factor of depending on which host device model is selected. In fact the default device model for both command line and GUI is rtl, which performs 10x slower than virtio, which is the most ideal option. Scope This tutorial does not focus on performance. Once the VF has been created, the network adapter driver automatically creates the infrastructure necessary to use it.

When using the macvtap method of connecting an SR-IOV VF to a VM, the host device model had a dramatic effect on all parameters, and there was no host driver information listed regardless of configuration. With the exception of the XL, which showed a link speed of 40 Gbps, all 10 GB adapters showed a link speed of 10 Gbps.

In order to find the PCI bus information for the VF, you need to know how to identify it, and sometimes the interface name that is assigned to the VF seems arbitrary. While the XL linkx better than the 10 Gb NICs, it performed at roughly 70 percent line rate when the iperf server ran on the VM, and at roughly 40 percent line rate when the iperf client was on the VM.

Performance is not significantly different than the method that involves a KVM virtual network pool of adapters. Lonux the desired VF comes into focus, click Finish. To autostart the network when the host machine boots, select the Autostart box so that the text changes from Never to On Boot. In the virt-manager Nitel, the following typical options are available: Unlike the previous method, this method does not require you to know the PCI bus information for the VF, but you do need to know the name of the interface that the OS created for the VF when it was created.

Using the Command Line Once the VF has been created, the network adapter driver automatically creates the infrastructure necessary to use 82559. So unless this ability to select which VF to use is a requirement for you, this is clearly the best method.

Additionally, I found that when all 4 VFs were inserted simultaneously using the virtual network adapter pool method into the VM and iperf ran simultaneously on all 4 network connections, each connection still maintained the same performance as if run separately.

I additionally evaluated the following: The primary disadvantage of this method is that you cannot intsl which VF you wish to insert into the VM because KVM manages it automatically, whereas with the other two insertion options you can select which VF to use.

All you need is the interface name of the physical function. Hypervisor default which in our configuration defaulted to rtl rtl e virtio Additional options were available on our test host machine, but they had to be entered into the VM XML definition using virsh edit.

Display all virtual networks. If you want to have the network automatically start when the host machine boots, make sure that the VFs get created at boot, and then: Share Tweet Share Send.

The following command instructs KVM to start the network just created. Summary When using the macvtap method of inteel an SR-IOV VF to a VM, the host device model had a dramatic effect on all parameters, and there was no host driver information listed regardless of configuration. Ease of Setup This is an admittedly subjective evaluation parameter.

As shown in the following figure, after creating the VF, use the bash script listed above to display the network interface names and PCI bus information assigned to the VFs. The one advantage to this method is that it allows control intl which VF is inserted into the VM, whereas the virtual network pool of adapters method does not.
