Installation/bridging settings of KVM in CentOS 5.6/virtual machine creation and operation
The/bin/qemu-KVM problem cannot be found when the kvm virtual machine is installed with libvirt In Ubuntu.
Two dell R710 hosts and two local hosts are installed with kvm virtual machi

If it is greater than 0, one or two of the conformances may support vmx or svm.3. install the software required by kvm.

In today's multi-tenant data center environment, virtualization technology is expanding from traditional virtual machine management program-based server virtualization to network virtualization. In this environment, software-based virtual switches are usually deployed on servers together with virtual machine management programs, and KVM is connected in a multi-tenant data center environment, virtualization technology is expanding from traditional virt

1. KVM Installation
First, check whether your processor supports hardware virtualization. If yes, run the following command:
Egrep '(vmx | SVM)' -- color = always/proc/cpuinfo
The following content should be displayed:

To virtualize multiple external tuservers on a server, it is used for the cluster. Several solutions have been taken into consideration. Because of the exclusion of the price, VirtualBox is good, but KVM is a Linux kernel layer and delivers better performance. Use is preferred. First, install Ubuntu12.04amd64server on an experimental machine. Upgrade the system patch and kernel. The hostname is kvmhost. The
, Redhat has developed more assistive tools for KVM, such as Libvirt Libguestfs, because the QEMU tool is inefficient and not easy to use.
1, first check whether the system support KVM, there are two prerequisites
A, the system is x86, by commanduname -a
B, CPU support virtualization Technologyegrep 'vmx|svm' /proc/cpuinfo
If you see an output, you prove that the CPU supports virtualization. Also pay sp

Because Ubuntu12.10 is just released, try it now. The installation of KVM is a bit different this time. The virtualserver is selected when the external tuserver is installed. This will cause ubuntu-virt-server and kvm-ipxe to be installed on the system. Therefore, after entering the system, you only need to install: ap
