Configuring a VM network interface
In this recipe, we are going to see a different model of a virtual network interface available to be used with a virtual machine and how to properly configure them.
Getting ready
As of Proxmox VE 3.4, there are four virtual network interface models available for a virtual machine:
Intel E1000
VirtIO (paravirtualized)
Realtec RTL8139
VMWare vmxnet3
Out of the four, Intel E1000 and VirtIO interfaces are the most widely used in the Proxmox environment. To achieve the maximum network performance possible, using VirtIO is recommended. Almost all Linux-based operating systems can automatically configure either virtual network interfaces. However, the Windows operating system installation media does not come with a VirtIO driver, which needs to be manually loaded. For Intel E1000, built-in drivers in Windows 7 and Windows Server 2008 work fine. However, for earlier versions of Windows or in some case for Windows Server 2012, drivers may be need to be provided manually...
