KVM seems to be stuck between Desktop (VirtualBox) and Server (Xen)

I have been using VirutalBox for quite some time as desktop Virtualization technology for running XP on Linux and Have also used Xen for Server Virtualization. Lately I have been quite interested in exploring and using KVM as a silver bullet - that is, to use it as general purpose tool.

The idea has been to use it as one seamless solution for both client/desktop and Server virtualization but my playing around and testing KVM makes me feel that:

  • VirtualBox is still the best free desktop virtualization technology
  • Xen seems to be still ahead of KVM in Server Virutalziation
  • KVM seems to be stuck between the two, trying to fulfill both the roles
My hopes have not all gone. I still think that sooner (or later?) KVM will provide an excellent general virt stack that we can use for both kind of usage.

The best thing with VirutalBox is that it provides the best easy to use feature. You resize the window of the XP guest and it seamlessly changes the resolution of the guest to make it totally seamless. You can share files between guest and host very easily. Try doing same with KVM and you need lots of technical stuff to configure to just share files between the two.

Xen is of course the most mature free server virtualization tech in widespread usage.
I tried running many KVM minimal guests (CentOS to be specific) on my Fedora 15 Laptop/Host. Gusts keep consuming 10 to 20% CPU even if they are idle!

The good thing with KVM is that it comes with the Kernel out of the box. Further, RedHat is investing heavily in development of various tools and the core of KVM itself. Spice is very promising project for desktop virt.

All that means, I will still keep following KVM closely.

Downgrade to Windows XP (from slow and blotted Vista)

Since the day I got my Vaio Z, I was feeling like vista is not allowing me to use the machine to its full potential. The trial of Office 2007 was also just too slow. Both the software look significantly blotted with unnecessarily stuff that most people do not use.

Ultimately I decided to use the downgrade option and downgraded the OS to Windows XP. The same machine now seems to run twice as responsive n fast!

I knew I will be getting performance improvements but did not thought, it will of this scale.

I recommend everyone who has an option to downgrade to use it and see if you feel like you have came out of jail.

My next move would be to totally move/migrate to Fedora or Ubuntu and stop using XP, except for testing on this platform.

Congrats! to President elect Barack Obama. Its a win for MySQL users as well.

Change Has Come to America in so many ways!

I congratulate President elect Barack Obama on his decisive winning of US presidential election.  We all welcome the change and hope that the economy the world over should rebound to new heights.

As per http://my.barackobama.com/page/s/techinterest we know that his offical web site used MySQL in the back end. So its a win for MySQL (and free and open source technologies in general).

Zaidsoft has been involved with deployment (and recommendation there of) of MySQL for most of Zaidsoft products. Its good that MySQL is really winning hearts and minds of people all over the world and the importance can be understood from the fact that the winning presidential candidate's web team is using it as well.

We sincerely hope that the first African American president is really going to bring all sort of positive changes.
