Care to expand on this? In reality, what matters is not the host, but the hypervisor. The hypervisor is what defines support of both host and guest. More importantly, it defines how well guests run on the hosted platform. For example, people tend to swear by VMware solutions, for various reasons. A big one is how VMware one only run guest OS, Windows. They assume the experience with Windows translates over to Linux guests as well. 9 times out of 10 I have to point most of these individuals at VMware's own documentation on Linux, or 3rd party solutions, on where VMware, or the 3rd party product, doesn't do things for Linux that it does for Windows. The same issues are natively address with Xen or KVM, let alone a full management solution in RHEV that just use the KVM HyperVisor with all sorts of support (ala like comparing VMware Workstation to ESX + vSphere platform). Another big one is not comparing VMware products and OS types to one another. A virtualization solution without management to one with (and quite costly at that). Comparing a server guest experience to a workstation type usage. There are many of these details that end up driving assumptions into areas where things don't work. Now I'm not going to argue that Xen 3.0.x in RHEL 5 fullvirt running Windows is the best, but that doesn't mean it's the only option for a RHEL 5 host. There are many of us running KVM in RHEL 5, Fedora and RHEL 6 Beta that have no issues, let alone deploying RHEV. And to expand options, VMware Workstation is a product that runs Windows well on older Linux host releases. In fact I've seen many people compare VMware Workstation on Windows to the Xen bundled with early RHEL 5 versions, without comparing apples-to-apples. That means comparing either Hyper-V bundled with Windows to Xen (or KVM for that matter) on RHEL, or VMware Workstation to VMware workstation on both Windows and Linux. Look at all options, make a comparison of all options. There are many HyperVisors and many options in solutions out there, for both Linux and Windows as hosts and guests that have varying experience and support. To sum it up to just Linux or Windows as a platform is not telling me much, hence why I'm asking for more details on this statement. ;) _______________________________________________ rhelv5-list mailing list rhelv5-list@redhat.com https://www.redhat.com/mailman/listinfo/rhelv5-list
