Have you tried it? The Citrix XenClient – bare metal (type-1) hypervisor for laptops/desktops. XenClient is a Open Source Software (OSS) that allows multiple Operating Systems (OS) to run concurrently on a single piece of hardware.
If you think that XenClient is just like any other desktop virtualization offerings (from VMware or Microsoft) then you are wrong. Let me explain why.
XenClient is a type-1 hypervisor – the Virtual Machines (VM) directly run off the hardware. Of cos with a thin software layer that help pass instructions to and fro between the VM and hardware. This thin software layer (the hypervisor) takes little resources and less prone to crashes as it isn’t as complex as a full fledge OS.
Other desktop virtualization offerings (e.g. VMware Workstation) currently are type-2 hypervisors. The VM runs off a virtualization software, that is in turn, running off a full fledge OS. The full fledge OS and virtualization software takes a chunk off your available system resources (CPU cycles, RAM, disk space, etc). It is more vulnerable as the host OS is susceptible to attacks and crashes (due to misconfiguration).

Didn’t really get to use VMware ESXi until recently where I need to set up some virtualization environment for demonstration purposes. Was originally looking at XenServer “Project Boston” (released on 16th May 2011) but chose ESXi in the end, not because ESXi is better than XenServer but instead:
- My previous mini-demo environment were based on VMware Workstation/Player
- Little time to explore new hypervisor hence sticking to what I have on hand
I told myself that I will try running Citrix infrastructure on XenServer the next time.

I’ve been neglecting this little technology blog of mine for quite sometime for some important personal stuffs – wedding! Yes, I am now happily married.
The past few months have been hectic. Rushing to and fro bridal shop, restaurants, printing shops, etc just to organise the event. The entire event, with the help of our brothers and sisters, was fantastic and everybody enjoyed themselves over the two weekends of celebration!
Now I will be doing up my cosy house, putting everything in place so that I have a proper place to post some reviews/hacks of my toys bought recently.
Anybody want to help out with my study room (discount, views & opinions)? Need recommendation on study table and computer. Considering a iMac! Just leave a comment or send me a tweet @shadowandy.
Have not been posting much lately due to the lack of Internet at my new place. Yeap, I partially moved in – staying at my new place during the weekends to set up the place and do some tidying up.
I have yet to subscribe to any Internet plans for the new place hence my only form of Internet is through my phone’s 3G plan. Kinda ironic for a “geek” like me, I thought I couldn’t surive without Internet… but… I did!
Any good deals for Internet? My new place is fibre ready, cable ready. Comes with the landline but didn’t activate any phone service on the landline.
