Choosing a CPU for virtualization and configuring it properly are just as important as choosing memory, storage and network resources. A processor that doesn't make sense for the infrastructure or one ...

Performance management in vSphere is all about sizing and allocating pools of resources. For CPU resources, the pools are the virtual CPUs (vCPUs) allocated to a virtual machine (VM), the physical ...

Linux kernel developers are considering a new “steal governor” designed to improve performance when multiple virtual machines compete for limited physical CPU resources. The proposal uses the amount ...

Software vulnerabilities come and go, but vulnerabilities found in hardware are significantly harder to deal with and lead to more problems, such as with Hertzbleed and that family of security issues ...

Hyper-V automatically optimizes NUMA placement, reducing manual tuning needs in virtual machine deployments. Adding virtual processors only helps when CPU bottlenecks exist and workloads can use them.

Extra processing power also lets users multitask more effectively. For example, one core could be used for surfing the Web, while the second core is handling an anti-virus scan. (Processor affinity ...

Virtual PCs have important uses, such as providing a dedicated environment for testing new applications or enabling the parallel operation of multiple operating systems. But the virtualization ...

In the area of cloud computing, i.e. on-demand access to IT resources via the internet, so-called trusted execution environments (TEEs) play a major role. They are designed to ensure that the data on ...

If you use virtual machines, there's reason to feel less-than-Zen about AMD's CPUs. Computer scientists affiliated with the CISPA Helmholtz Center for Information Security in Germany have found a ...
