System Requirements

 

These topics provide system requirements for each supported environment.

Minimum Hardware and Software Requirements for KVM

Table 1 lists the hardware requirements.

Table 1: Minimum Hardware Requirements for KVM

Description

Value

Sample system configuration

For lab simulation and low performance (less than 100 Mbps) use cases, any x86 processor (Intel or AMD) with VT-d capability.

For all other use cases, Intel Ivy Bridge processors or later are required.

Example of Ivy Bridge processor: Intel Xeon E5-2667 v2 @ 3.30 GHz 25 MB Cache

For single root I/O virtualization (SR-IOV) NIC type, use Intel 82599-based PCI-Express cards (10 Gbps) and Ivy Bridge processors.

Number of cores

Note: Performance mode is the default mode and the minimum value is based on one port.

To calculate the optimal number of vCPUs needed by VFP for performance mode:

  • Without CoS—(2.5 * number-of-ports) + 3

  • With CoS—(3.5 * number-of-ports) + 3

For lab simulation use case applications (lite mode): Minimum of 4

  • 1 for VCP

  • 3 for VFP

For low-bandwidth (virtio) or high-bandwidth (SR-IOV) applications (performance mode): Minimum of 8

  • 1 for VCP

  • 7 for VFP

Memory

Note: Performance mode is the default mode.

For lab simulation use case applications (lite mode): Minimum of 5 GB

  • 1 GB for VCP

  • 4 GB for VFP

For low-bandwidth or high-bandwidth applications (performance mode): Minimum of 16 GB

  • 4 GB for VCP

  • 12 GB for VFP

Additional 2 GB recommended for host OS

Storage

Local or NAS

Other requirements

Intel VT-d capability

Hyperthreading (recommended)

AES-NI
