I'm running this on CentOS 6.5

• Download qcow2 image

• Create an additional virtualized bridge on CentOS if you need to. Example:

  # virsh net-dumpxml cisco
  <network>
    <name>cisco</name>
    <uuid>2fb420fb-943c-e5be-0769-0b2700c9d7e0</uuid>
    <bridge name='virbr1' stp='on' delay='0' />
    <mac address='52:54:00:2B:F6:26'/>
    <ip address='192.168.200.1' netmask='255.255.255.0'>
    </ip>
  </network>

• 4 GB memory.
• 3 virtio network interfaces. For example 2 in the virtual isolated Cisco network and 1 to your own network.
• Select the downloaded qcow2 image as storage.
• Add serial port as first serial device. Select TCP net console (tcp), for example 127.0.0.1:4555 and select 'Use Telnet'.
• Run the virtual machine.

• Enable serial console and reload.

  #en
  conf t
  platform console serial
  ctrl-z
  copy run start
  reload

• Log in using telnet on the KVM host.

  telnet localhost 4555

• After install, throughput is set to 2,5Mbit.

  #sh platform hardware throughput level
  The current throughput level is 2500 kb/s

• Cisco CSR 1000V offers a 60-day evaluation license. The evaluation license is for the Premium technology package. Accept the license:

  Router>conf t
  #license accept end user agreement

• Configure evaluation licence.

  #license boot level premium

• Copy running-config to start-config and reload.

• Throughput:

  #sh platform hardware throughput level
  The current throughput level is 50000 kb/s

• License:

• Show interfaces.

  #sh ip int br
  Interface              IP-Address      OK? Method Status                Protocol
  GigabitEthernet1       unassigned      YES NVRAM  administratively down down    
  GigabitEthernet2       unassigned      YES NVRAM  administratively down down    
  GigabitEthernet3       unassigned      YES NVRAM  administratively down down    

• Create management VRF.

  conf t
  Router(config)#ip vrf mgmt-irf 
  Router(config-vrf)#int g1           
  Router(config-if)#ip vrf forwarding mgmt-vrf
  Router(config-if)#^Z
  
  #sh run int g1
  Building configuration...
  
  Current configuration : 105 bytes
  !
  interface GigabitEthernet1
   ip vrf forwarding mgmt-vrf
   no ip address
   shutdown
   negotiation auto
  end

• Configure IP address.

  conf t
  Router(config)#int g1
  Router(config-if)#ip add 1.2.3.4 255.255.255.0
  Router(config-if)#no shut
  Router(config-if)#^Z
  

• Show interfaces.

  Router#sh ip int br
  Interface              IP-Address      OK? Method Status                Protocol
  GigabitEthernet1       1.2.3.4         YES manual up                    up

  GigabitEthernet3       unassigned      YES NVRAM  administratively down down    

• Ping test.

  Router#ping vrf mgmt-vrf 1.2.3.2
  Type escape sequence to abort.
