  2. From My Virtual Desktop: VMs and vCPU Usage

    Hello,   So - you have a virtual machine with two vCPUs pinned, but you want to "see" the CPU activity, etc.  You have tried Task Manager/Device Manager (Windows) and can only see:   or This only tells you the virtual machine's perspective (domU) of its vCPU utilization.  Dom0 (the control domain) does not necessarily see the domU CPU activity: per core, per vCPU, etc, etc.   If you want to really ...

  4. Citrix XenServer – Setting more than one vCPU per VM to improve application performance and server consolidation e.g. for CAD/3-D graphical applications

    Many rich graphical applications such as CAD applications may benefit from allocating more than 1 vCPU per VM (1 vCPU is the default) via XenCenter or the command line. This will be of interest to many of those evaluating XenDesktop and XenApp HDX 3D Pro GPU pass-through and GPU sharing technologies and can lead to noticeable performance enhancements. The performance gains possible though are highly ...

  10. Xen and open-source

    One of the things I love about Xen is that it's been open since its beginnings. Xen came out of the XenoServers research project at the University of Cambridge Computer Laboratory. This project was conceived in the late 1990s to investigate how to build a public infrastructure for wide-area distributed computing, in effect a forerunner of what we call cloud computing today. Early XenoServers work ...
