CPU, Eric Siebert, ESX, scheduling, VMware

Recently someone asked me what VMware scheduling is, so I thought I would cover that in this blog post. Scheduling, or virtual CPU scheduling, happens behind the scenes and is not a very visible component of virtualization, but is absolutely critical for virtualization to work properly. You...

Although there are several tech notes that suggest otherwise, most Lotus Domino workloads can be successfully virtualized. I thought I'd review some of the tech notes as they seem to be discouraging people from virtualizing Domino servers. Both of the notes I'll review blame the virtualization...

Edward L. Haletky, ESX, ESX 4, Texiwill, VMware, VMware vSphere 4, vSphere

One of the things VMware's products allow administrators to do is space out hardware upgrades, but that will soon change with the release of VMware vSphere. VMware vSphere's hypervisor uses a 64-bit kernel. What this means is that vSphere ESX 4 is a 64-bit operating system that requires 64-bit...
