Running Barracuda Spam and Virus Firewall 300 out of Hyper-V

First of all, thanks very much to this blog: without it, I wouldn’t have been able to get as far as I did. Anyways, now on to virtualizing a Barracuda Spam and Virus Firewall–

Things you will need:
1. Barracuda E-mail Spam Filter
2. Windows 2008 R2 Hyper-V server (VMWare probably works too… only thing I wouldn’t be sure of is how VMware portrays the mount points and what drivers it uses for legacy network adapters)
3. Acronis True Image (or similar bootable “ghosting” media)

The first step is to make an image of a Barracuda. Using the BIOS code from the aforementioned blog, login to the BIOS of the Barracuda and enable Boot from CD as the first boot option. Then connect a USB CD-ROM drive with Acronis True Image. Also connect a USB hard drive with enough space to accommodate at least 32GB worth of data.

Create the TIB image of the entire drive. Remove the USB drive when you are done and connect it to your Windows 2008 R2 Hyper-V server. Create a new virtual machine with 1 CPU, about 1GB RAM (my 300 only came with 512mb… max 2GB according to the motherboard specifications) and a legacy adapter. I also turned on Windows NT CPU support just to play it safe. Remove the SCSI controller and create a fixed 32gb VHD for the OS. Attach an ISO of Acronis True Image and boot the VM to Acronis.

I created a second VHD in the host OS and copied the TIB file into it, then mounted the VHD as a secondary IDE drive. This was the easiest way to get the VM to restore the TIB file… plus at any time I can reboot into Acronis and reimage my system.

Restore the image and reboot. You will want to follow the steps from the previously mentioned blog to gain root access. This is necessary to make the network card work. Once you have root access, modify the /etc/modules.conf file. Change the eth0 alias to use “tulip” instead of “via-rhine.” Type modprobe tulip to verify, then ifconfig to double check eth0 is now available.

This is a great way to avoid having to purchase instant replacement, and in a suitable backup environment… disaster recovery is a breeze if you backup your virtual machines for instant disaster recovery. Creating the image doesn’t void the warranty as long as you can avoid opening the case. However, if you ever experience problems… hopefully they don’t notice your hardware specs 🙂 I’m not sure how much lspci differs from appliance to virtual machine, I haven’t gotten that deep into it yet.

Just an FYI, if you ever need to manually update firmware because the web interface is broken… look for /home/emailswitch/code/firmware/current/bin/ and run with the argument “firmware”

i.e. ./ firmware

Add -c at the end to perform a check only.

Just about every function of the web site is a perl script… doing some cat/grep operations on the index.cgi should help you out if you are ever in a bind.

  1. Had to clone my EMAC, but other than that, this worked like a charm. Plus, the increase in hardware performance have made this thing easily 40X faster.
