Today's small series for you to introduce what is hard disk virtualization and operating system and hard disk virtualization relationship. Operating system virtualization is at the top of the operating system. This approach can greatly improve the server consolidation rate and resource utilization of many computing environments. When users use virtualized produc

This paper tests the physical machine as centos6.5 Physical machine using INTEL-V virtualization architecture, installing QEMU-KVM version 0.12 We know that KVM virtualization technology requires server hardware support virtualization (INTEL-V/AMD-T) to improve virtual machine performance, if we need to test an OpenStack cluster, but not too many physica

1 Active Directory networks based on Windows Server R2In virtualized applications, both the underlying server Hyper-V server, Windows Server 2008 with the GUI, Windows Server 2012, or the Virtualization management tool, VMM, are inseparable from Active Directory support. In addition, for other Microsoft applications, whether it's virtualization or cloud-related, active Directory, such as DHCP, Windows Deplo

Virtualization (1): Introduction to virtualization and Vmware products The latest version of VMware Workstation is 10.0.2. I believe everyone has also used it. The creation and deletion of simple virtual machines are very simple. I will not detail it here. Next I will briefly introduce the advanced use of VMware Workstation.1 VNC connection VM This function is provided by VMware Workstation. You can bind a

You have configured this virtual machine to use a 64-bit client operating system. However, the 64-bit operating system is unavailable. This host has virtualization support capabilities, but virtualization technology is disabled.This is usually because virtualization technology has been set or disabled in BIOS/firmware or the host has no permission to change this
