I’ve read some posts (see in the bottom of this post for the references) and I notice how the hypervisor comparison and choosing criteria are still a interesting trend and not only a marketing battle between different vendors (and maybe there will be more interest will be on this aspects with the release of Windows Server 8). But in several cases the comparison is limited to the hypervisor technical characteristics (and I’ve already written something about Hyper-V 3.0, XenServer 6.0 and RHEV 3.0) without considering (except in some cases) that the those are only one […]
In the previous post I’ve esplain how to install XenServer 6.0 (but can works also with previous versions) in a VM, using VMware products like Workstation 8 or vSphere 5. To build a XenServer Pool (that is basically the same of a VMware Cluster) you need at least two hosts and a shared storage (and of course a shared network). I suggest to do not clone the second host from the fist because XenServer works with several UUID and in this way you will clone also the host UUID and XenCenter will be not able […]
As written in a previous post, Citrix with XenServer 6 is trying to fill the gap from VMware vSphere… and most features (included distributed virtual switches) are now common also in this type of solution. Of course features are only one of the possible criteria to select an hypervisor and a virtualization solution. To make some practice or just to have a look at the product, it is possible run it in a VM on VMware products, both Workstation 8 (and probably also 7) and vSphere 5 can be used.
One trend in the last year(s) is that the virtualization ecosystem is growing outside the boundary where was born: historical partner vendor of VMware now are extending their solution to other hypervisors, and also also new products are designed to managed a more complex virtual environment. This was also called “Hypervisor Agnosticism” in a VKernel post. We do not talk about interoperability across different hypervisors, but simple use same tools, especially for management, monitoring and data protection, for more type of products. Does it make sense? For a single customer maybe not… have multiple environment […]
The new major release of Citrix’s hypervisor was released on Sep, 30 2011 (XenServer 6.0 is here! ). For more info see also the Release Notes for Citrix XenServer 6.0. Architectural Changes: The Boston release is based on the open-source Xen 4.1 hypervisor. XenServer is another commercial product to ship with the Xen 4 hypervisor. For those of you who like to follow the open source world, Oracle VM 3 launched a few weeks ago, and is based on the Xen 4 hypervisor. Ubuntu Server 11.10 will soon follow with support for Xen 4, and […]
