Howto Convert Vmware Image to Virtualbox Image

VirtualBox is a family of powerful x86 virtualization products for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL).

*cough* *cough* QEmu/KVM anybody?
And only the free edition of VirtualBox is GPL. There also is a more feature-rich commercial edition.
So basically what you get with the GPL-version is sort of a preview, albeit quite mighty and already rich of features, but still something that is cut down from a more complete version.

You don't have this problem with QEmu/KVM. And I don't know about VirtualBox, but QEmu/KVM now also go beyond full virtualization and offer partial para-virtualization through virtio.

Aside from that there are other truly free solutions. Bochs for example. Although it cannot even closely match the speed of QEmu/KVM it still is a fully free virtualization-solution and surely has it's place.

Yeah, the biggest thing

Yeah, the biggest thing about virtualbox for me is the graphical interface which is easy to use, but for QEMU/KVM there is Virt Manager since recently.

Actually Virt Manager has

 

Actually Virt Manager has been around for a while too. I think I remember having it already back in Fedora 7. But at least since Fedora 8.
The latest version now also supports VirtIO network-cards. The previous had support for VirtIO hard-drives, but the NICs were still missing. That has been fixed now so that you can have both VirtIO HDs and NICs. Didn't compare performance yet by using a benchmark, but it already feels a lot better.

So, as said, QEmu/KVM is moving into the realm of Xen and VMWare by now having para-virtualization for certain components.
