Examples described relate to associating virtual network interfaces with a virtual machine during provisioning in a cloud system. In an example, during booting of a virtual machine in a cloud system, a number of network interfaces associated with the virtual machine may be determined. A further determination may be made whether the number of network interfaces associated with the virtual machine is less than a number of network interfaces specified for the virtual machine to perform a function. In response to a determination that the number of network interfaces associated with the virtual machine is less than the number of network interfaces specified for the virtual machine to perform the function, an internal virtual network kernel interface may be created. The internal virtual network kernel interface may be associated with the virtual machine. The virtual machine may be provisioned in the cloud system.
