Since the RHEL6 version, Redhat is not the original support Xen, instead of the embrace of KVM. Although KVM claims to support the full virtualization of HVM technology, KVM started late after all, far less mature than Xen technology, the system crashes often occur when running multiple instances, and certainly does not exclude the possibility that future KVM will be more efficient. So there are only two ways to install Xen, one is to download the sou

OpenVZ is synonymous with Linux-based VPS. Generally, OpenVZ cannot directly Virtualize Windows servers. However, we can install KVM in LinuxVPS to build a Windows environment. This solution applies to CentOS 5 series 32-bit and 64-bit systems. The virtualization environment is OpenVZ. Of course, the virtualization of the XEN and KVM architectures is also possibl

First, KVM IntroductionKVM (kernel-basedvirtual machine), a kernel-based VM, is a virtualized infrastructure used in the Linux kernel to transform the Linux kernel into a hypervisor. KVM was introduced into the Linux 2.6.20 core in February 2007 and ported to FreeBSD and Illumos in a way that can load core modules.KVM runs on an x86 platform with Intel VT or AMD-V capabilities. It is also ported to the S/390,POWERPC and IA-64 platforms. In Linux kernel version 3.9, support for the ARM architectu

From CPU, memory, motherboard to server, who will be the next beneficiary of the virtualization camp as more and more IT system core components choose to join the virtualization camp? From the current development situation, server virtualization is becoming mainstream, storage is very likely to become the next one because of
