Reading Time: 4 minutes Recently, during VMworld US 2018, VMware has celebrated the 20 years of the company. But there is another virtualization project that has a lot of history like VMware: the Xen Project and this October marks our 15th anniversary. On October 2003, Ian Pratt (founder of the Xen Project) announces the first stable release of the Xen virtual machine monitor for x86, and port of Linux 2.4.22 as a guest OS. It was one of the most popular open source hypervisors and amasses more than 10 million users; but now there is a clear rise of KVM and also […]

Reading Time: 4 minutes 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 […]

Reading Time: 3 minutes 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 […]

Reading Time: 3 minutes 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.

Reading Time: 4 minutes PHD Virtual Monitor is a comprehensive virtualization monitoring solution that gives you complete visibility across your entire virtual IT infrastructure at all levels including virtual, physical and application. So it not only a multi-hypervisors monitor tool (as described in the previous post), but also a multi-environments tool. This could be really interesting with Citrix XenServer environments where the monitoring feature are quite minimal (and without simple notification in the free edition): CPU and Memory, both for hosts and VMs; and from latest version also networking and disks (but disk only for VMs). Also the graphs […]

Reading Time: 3 minutes 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 […]

Reading Time: 3 minutes 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 […]
