To make this even more interesting, Novell uses the Xen open source hypervisor in its SUSE Linux Enterprise and OpenSUSE Linux distributions. So what's the net effect of Citrix swooping in? Smiles all around, judging from an Internetnews.com article.
Xen project leader and XenSource founder, the suddenly much richer Ian Pratt, is quoted to the effect that "there are over 20 major corporations, as well as plenty more individuals and smaller companies, that regularly contribute to the Xen open source software project." Citrix's new interest is seen as a rising tide that will lift all the boats in the Xen community.
In that sense the XenSource acquisition follows the Red Hat model, which has built a business on open source, as well as Novell's SUSE Linux acquisition -- which is something Microsoft must be thinking deeply about as it prepares to launch Veridian.
Does it mean the Redmond software company will have to fight on another front in its war against open source? And how many fronts can it fight on as technology advances?
