Integrating vSRX into VIRL

 1. Convert ‘thin provision’ image to ‘fat provision image’. This can be done usingthevmware-vdiskmanager as per below:

 /Applications/VMware\ Fusion.app/Contents/Library/vmware-vdiskmanager -r "junos-vsrx-12.1X46-D10.2-domestic-disk.vmdk" -t 0 “junos-vsrx-12.1X46-D10.2-domestic-disk1.vmdk"

2. The image needs to be modified to accept configuration file injection. This must be done BEFORE loading the image into VIRL via the User World Management (Skinned OpenStack) interface.

You can run the command above on your VIRL VM, so copy the image into the VIRL VM and execute there.

sudo kvm -M pc-1.0 -enable-kvm -daemonize -m 2048 -smp 2,sockets=2,cores=1,threads=1 -hda ./junos-vsrx-12.1X46-D10.2-domestic-disk1.vmdk \
-serial telnet::9101,server,nowait -net nic,model=e1000,vlan=1001,macaddr=00:01:00:ff:88:01 -nographic;telnet localhost 9101

login as ‘root’Edit the file /etc/fstab (nano /etc/fstab). The /etc/fstab should look like this (thevtbd1 disk is theconfig disk)

Device Mountpoint FStype Options Dump Pass#
/dev/md0 / cd9660 ro 0 0
proc /proc procfs rw 0 0
#/dev/bo0s1e /config ufs rw 2 2 
/dev/bo0s1b none swap sw 0 0
/dev/vtbd1s1 /config msdosfs rw 0 0

 

* /dev/bo0s1e /config ufs rw 2 2 is the old configuration disk.

* /dev/vtbd1s1 /config msdosfs rw 0 0 This is the FAT configuration disk.

Save the file.

Now we need to remove the SSH key. Remove the file with:

/etc/ssh/*key - 'rm /etc/ssh/*key

Shut the VM down.

3. The VM image is now ready to be loaded into UWM as a vSRX image.

You can add the vSRX image to your VIRL server under the ‘admin/images/’ menu by selecting ‘add’ and choosing ‘VSRX’ from the pick list, as per the picture:

 NOTE – If you want to make the vSRX image your default vSRX image, leave the Name/Version field blank. You can put release version information in the ‘release’ field.

If you create a topology with a vSRX node in it, at simulation start time, the system will look for a default vSRX image. If there is no default image, the simulation will not start and you will need to specifically set the VM_image and VM_flavor field values to the vSRX image that you’ve registered.

Configuration text placed in the ‘configuration’ field for the vSRX, will be automatically loaded into the VM at boot time. A correctly formatted JUNOS configuration will be applied assuming that there are no syntax errors! If you want to provision the VM with a basic set of user accounts, the configuration snippet below can be applied:

system {
  root-authentication {
    encrypted-password "$1$zdCNVrJU$xNlhBZZk8WOn8z3vl6LEs/"; ## SECRET-DATA
                      }
       login {
            user juniper {
                full-name juniper;
                uid 2001;
                class super-user;
                         authentication {
                         encrypted-password "$1$uRcJqW9g$ldwpqqgCZW17bw/tBUeFk/"; ## SECRET-DATA
           }
       }
    }
}

Your mileage may vary with this. VIRL is fun because there are lots of things happening behind the scenes.
