Oracle VM vs. VMware: A closer look
Have you narrowed your virtualization platform choices to VMware and Oracle VM, or do you want to
compare Oracle VM with the virtualization leader? Here we compare Oracle VM with
VMware and offer other resources, such as tips and articles.
Xen vs. KVM Linux virtualization hypervisors
Linux virtualization supporters fall into two camps: the Xen and KVM factions . Proponents of Xen
argue that the Xen virtualization architecture is more robust, enjoys a broad array of management
tools and delivers excellent performance. KVM advocates, on the other hand, note that the
Kernel-based Virtual Machine architecture is powerful and easy to implement. In this Xen
vs. KVM face-off, two virtualization experts debate which open source hypervisor is better.

for virtualization software But VMware's dominance doesn't mean other vendors haven't offered up
viable alternatives. Oracle and Citrix have both ventured into the server virtualization
marketplace and base their products on open
source hypervisor Xen. This article explores how Xen -- with its many advantages, such as lower
pricing and robust support -- is positioned to challenge VMware down the road.
