Unetlab – Setting up vIOS and ASAs

More fun with UnetLab today!

I am back to running it on the ESXi server, so have plenty of memory and CPU cores. It should be nice and fast!UNetLab on ESXi

Yesterday was fun, I added IOL images and XRv, so today let’s add vIOS, and, if I can, an ASA!

vIOS on UnetLab

I am going to try and get the vIOS images from the OnePK (all in one image) running. Andrea already has a guide to this, so it shouldn’t be too hard. The original documentation is here.
Firstly you can see the amount of space I have free, I then copy (using FileZilla) the OVA file onto the VM, and again you can see the space taken up. I then follow Andrea’s steps (though I did play with the folder name…)

Following the documentation through (or so I thought), I then created a lab, added a network, and tried to add a vIOS node.

But the list was empty.

So, I read through the doc again, and some of the comments. Andrea tells us what the image name should be, so I created a folder to match the version, and moved the HDA file into there:

Now we are good!

Adding UNetLab nodes

Topology

The topology looks like this: Running vIOS on UNetLab

So let’s try configuring the routers!

Router(config)#ho vIOS-1
vIOS-1(config)#int gi 0/0
vIOS-1(config-if)#ip add 10.1.1.1 255.255.255.0

Easy.

I took the first screenshot at 13:22, it’s now 13:58, and I have written this whilst setting it all up. 30 minutes or less!

ASA on UNetLab

Not sure how this will go. There isn’t a guide for it, so It’s going to be a lot of guess work!

I start by copying the two VMDK files I have to the /tmp directory:

[email protected]:/# ls /tmp
ASA-8.42-1.vmdk  ASA-8.42.vmdk
[email protected]:/#

Then I convert them:

[email protected]:/tmp# qemu-img convert -f vmdk -O qcow2 ASA-8.42.vmdk hda.qcow2
[email protected]:/tmp# qemu-img convert -f vmdk -O qcow2 ASA-8.42-1.vmdk hdb.qcow2
[email protected]:/tmp#

I then move to the right directory, and move the files there:

[email protected]:/opt/unetlab/addons/qemu# mkdir ASA-8.42
[email protected]:/opt/unetlab/addons/qemu# mv /tmp/hda.qcow2 ASA-8.42/
[email protected]:/opt/unetlab/addons/qemu# mv /tmp/hdb.qcow2 ASA-8.42/
[email protected]:/opt/unetlab/addons/qemu# /opt/unetlab/wrappers/unl_wrapper -a fixpermissions
[email protected]:/opt/unetlab/addons/qemu#

Surprisingly… There is nothing there when I try and add a node:

UNetLab missing node

At this point I started reading some of the other documents. I went through all of them until I got to the F5 BIG-IP document. Here we have another example of a 2 part system. I was happy that I had named the files hda and hdb, but then I thought – let’s just try making the folder name lower case. So I edited it in FileZilla:

[email protected]:~# ls /opt/unetlab/addons/qemu/
asa-8.42  vios-adventerprisek9-m15.4-1.2.0-173  xrv-k9-5.2.2
[email protected]:~#

All of a sudden, I have the option for ASAs!

Running ASAs in UNetLab
So. let’s create a new lab and connect everything up!
Running ASAs in UNetLab
This has all been a bit of a shot in the dark. Not knowing if I could get them running, I thought I would give it a go. But here is the thing…. are they usable?
There is a moment of wonder, as I sit staring at a blank telnet session, then suddenly…
Running ASAs in UNetLabLet’s just prove we can run them, and have connectivity between them:
ciscoasa(config)# hostname ASA1
ASA1(config)# int gi 0  
ASA1(config-if)# ip add 10.1.1.1 255.255.255.0
ASA1(config-if)# nameif Outside
INFO: Security level for "Outside" set to 0 by default.
ASA1(config-if)# 
ASA1(config-if)# no shut
ASA1(config-if)# 

ciscoasa(config)# hostname ASA2
ASA2(config)# int gi 0
ASA2(config-if)# ip add 10.1.1.2 255.255.255.0
ASA2(config-if)# no shut
ASA2(config-if)# nameif Outside
INFO: Security level for "Outside" set to 0 by default.
ASA2(config-if)#  

ASA1# ping 10.1.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/10 ms
ASA1# 

ASA2# ping 10.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/10 ms
ASA2#

Wow!

So, in two days, with a total of about three hours, I now have one environment that will run IOL routers, XRv routers, vIOS routers and ASAs.

Now that is impressive!

I might even try and add Titanium to UNetLab as well! But not today.
