VMware KB: VMware VirtualCenter Server service does not start automatically after reboot

This issue may occur if the VirtualCenter Server service starts before one of the services it depends on is started. The VirtualCenter Server service is dependent on the following services: SQL Services ADAM Services when using linked mode in vCenter Server 4.x To resolve this issue, add a dependency to the VirtualCenter service so that it starts only after the necessary services have started.

Yikes!  You need to edit the registry to get this to work.

Quantum Processor Hooks Up with Quantum Memory

Although quantum computing is now mostly a research subject, it holds out the promise of computers far more capable than those we use today. The power of quantum computers comes from their version of the most basic unit of computing, the bit. In a conventional computer, a bit can represent either 1 or 0 at any time. Thanks to the quirks of quantum mechanics, the equivalent in a quantum computer, a qubit, can represent both values at once. When qubits in such a “superposition” state work together, they can operate on exponentially more data than the same number of regular bits. As a result, quantum computers should be able to defeat encryption that is unbreakable in practice today and perform highly complex simulations.

Reading this makes my head want to explode.

CloudStack, The Best Kept Secret in Cloud Computing

Cross Hypervisor Support

With CloudStack you can use multiple hypervisors, proprietary or open source (VMware, XenServer, Xen Cloud Platform, KVM or OracleVM). Not only can you use whatever hypervisor you want but also you can use multiple hypervisors in a highly available cloud computing instance.

Importing Kensho OVF to ESX

OVF is a format that describes virtual appliances; these could be single or multiple machine. In doing so, OVF describes the virtual hardware and physical requirements of each machine.

In my example I am going to use XenConvert to create an OVF Appliance from a XenServer XVA (that is an export of a XenServer VM), modify that using a VMware created OVF, and then import to ESX.

VMware ESXi vs. XenServer: Cloud and Desktop Feature Showdown

Heavyweight companies from around the globe are competing in the hot cloud space. In the center ring are two tough competitors Citrix and VMware. Each has strengths and weaknesses. Which should you choose?

In this article, I compare the hypervisor products from these two vendors, Citrix XenServer and VMware ESXi, and explore what each as to offer developers. Since hypervisors have become are a dime a dozen, it only makes sense that a comparison of VMware ESXi and Citrix XenServer also discusses the surrounding components to get a full picture of what each can do for the development
