For the configuration of the hypervisor, there are two lines of configuration in the default profile STACKRC of the Devstack source code library: Virt_driver=${virt_driver:-libvirt} LIBVIRT_TYPE=${LIBVIRT_TYPE:-KVM} Therefore, when Devstack installs OpenStack, the default is to set Libvirt as Hypervisor driver, using QEMU/KVM as

KVM Virtual machine migration is divided into 4 types (1) Thermal migration is based on shared storage (2) Thermal migration based on local storage (3) Cold migration is based on shared storage (4) Cold migration based on local storage This is a hot migration based on local storage.

Currently, the virtual machines virtualized by the company in KVM are dual ip addresses, that is, a floating ip address and a fixed ip address used by a virtual machine. When installing the jboss application server, the host. xml configuration file must specify the management ip address for managing the application server. In this case, there is a problem with the Configuration: The specific analysis is as follows: 1. If the Configuration Management i

I installed Ubuntu11.10, which is relatively good and stable. It is also possible. UAC control is similar to that of Win7, that is, it is easy to use. I think the best of it is the software warehouse, which is a powerful tool. No worries about installing any software. So I have always wanted to try its KVM, which is supported by kernel 2.6 or later versions. It is said that the speed is fast. Anyway, my CPU also supports the VT technology. Why not? Th

Use Shell scripts to monitor KVM virtual machines Recently, a friend asked me what software I usually use to manage KVM virtual machines. In fact, I usually use the virsh command to manage virtual machines through the command line. Although RedHat has a virtual machine management and monitoring platform, it can only be used on the redhat release. Other platforms are not associated with this software, includ
