Xen virtualization uses "semi-virtualization" (para-virtualization), all hardware is only scheduled through the Xen hypervisor, compared to VMware Server and workstations to virtual complete hardware device performance is much better! But has always been used when there is a problem: "Virtual network"! Today, I found the latest BATE package for the Virt-manager (RHEL5 GUI tool for managing virtual machines) on RHN. Ha ha.... The virtual network has become simpler from today! 1, download the fol

QEMU Guest AgentIt is a daemon program running inside the domain which are supposed to help management applications with executing function s which need assistance of the guest OS. For example, freezing and thawing filesystems, entering suspend. However, guest agent (GA) is not bullet proof, and hostile guest OS can send spurious replies.Setting QEMU GA upCurrently, QEMU exposes GA via Virtio serial port. There is some attempts to allow applications to use QEMU Monitor for communication with GA,

It's a good thing to create KVM on centos6.5, and there are some problems on the centos7.1, which are documented here, reference documentsHttps://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Virtualization_Deployment_and_ Administration_guide/chap-network_configuration.html#sect-network_configuration-network_address_translation_ Nat_with_libvirt# yum Install virt-install Libvirt-python virt-manager python-virtinst

Installation (Installation)Here, for example, Ubuntu Linux 10.04, install KVM.First, install the KVM-related basic kit: Libvirt-bin: Provides LIBVIRTD to manage QEMU and KVM. QEMU-KVM: The main virtual engine. Ubuntu-vm-builder: A powerful virtual machine tool. Bridge-utils: Used to build a bridge used by virtual machines. Install with apt:sudo apt-get install qemu-kvm libvirt-bin
