Even with the new release of VirtualBox 1.6 the iPhone is still not working with iTunes. The same error is occuring, which forces iPhone users to maintain their dual boot capabilities with a Windows OS. My excitment was high for the 1.6 version of VirtualBox. I am eager to dump my Windows partition to free up hard drive space, and this requires a functional iTunes in VirtualBox. This issue will inevitably be resolved, and therefore patients is required.

The USB iPhone driver is not currently compatible with VirtualBox. It causes an error that does not allows iTunes to connect to the iPhone. Obviously this is incredibly frusterating for all Linux users that own an iPhone. Luckily I had Windows Vista installed on my laptop and was able to activate the iPhone completely. Then I backed up all my music and videos, installed Ubuntu, cloned by backed-up Windows XP guest OS, installed iTunes, and viola no iPhone support.
You’ll get some message like 0xe8000001 or something of the sort when you plug your iPhone in. This is extremely frustrating. There is no Linux support by MAC, and VirtualBox is not resolving this issue in a timely manner. It seems that this has been an issue for some months now; this can easily be observed by the frustration in the VirtualBox forums and others.

I highly recommend JanusVM for your iPhone VPN solution. Janus incorporates squid, tor, and privoxy providing much more than just a VPN. Squid is a proxy server, which will speed up your connection slightly. Tor is a network of servers around the world that will scramble your network traffic so its practically impossible to track who or where you are. And privoxy will strip all sensitive data from your website browsing to further improve your wireless security. Obviously the VPN part of Janus will allow your iPhone to have a secure connection to the internet, so you can access wifi anywhere without fear of anything!!!
The best part is JanusVM is that it’s completely free. I highly recommend donating a little money if you have it. The author of the software is providing a great service to the open source community, and now allows iPhone users to have a secure, reliable, and instant VPN solution!

Just pop JanusVM into a VirtualBox machine, and setup host networking to grab an external ip address. Configure your iphone to access your external ip address, the associated pptp port (port 1723), and viola your VPN should be up and running in about 15 minutes worth of configuration 
In the future I will post a graphical tutorial on this, but for now try searching this blog, in the upper right hand corner, for more information about setting up virtual machines and configuring host networking.

Nagios allows you to graphically monitor your virtual servers from a single web page. No longer will you have to load each individual website or web service in order to verify consistent operation. Nagios can be downloaded directly from their website at:
http://www.nagios.com
On the Nagios homepage is a link to a 15 minute tutorial, which is relatively straight forward, and works like a charm. My next blog post will cover the same material that is included in their 15 minute tutorial. In this post I want to briefly discuss which guest operating system to use for maximum stability. I highly recommend Ubuntu JeOS for your virtual OS specifically because the kernel works flawlessly with the host operating system. To recap, I currently use Debian Etch as my host OS, and with JeOS as the guest the host CPU load is only active when the guest is actually processing data. I previously used Debian Etch also as the guest OS, and it would have a constant CPU load on the host. This was not at all desirable, and with a quick transition to JeOS the problem was swiftly resolved.
The first step to get Nagios up and running in a VirtualBox guest OS is to install a clean JeOS in a new guest OS.
Step 2 is setting up Nagios. You can follow the 15 minute tutorial on their website, which is indeed perfect, but I will also post the procedures asap.
