The hype over hypervisors was well into a full foam as EMC announced the deal. But when the VMware shares hit Wall Street, the resulting rich and creamy lather reminded one and all the tech IPO madness of the late 1990s could still rise to haunt us.
Citrix turned out its pockets and found $500m to acquire XenSource, the developer of the open source Xen hypervisor. The enormous sum gave Citrix some much-needed market appeal while giving XenSource the corporate R&D backing to fight its hulking rival VMware.
XenSource had previously been struggling to capture a significant piece of the virtualization battlefield despite strong ties with both Linux and Windows camps. Sun and Virtual Iron are tinkering away at their virtualization products based on Xen as well.
