1. KVM is divided into two parts: qemu-KVM and KVM-kmod. Qemu-KVM is the user space part of KVM. It can be seen as a modified version of the qemu simulator. It replaces the dynamic binary translation part of the qemu command and creates and starts virtual machines by using I

The KVM virtual machine on it is deleted, each virtual machine contains a disk file in Qcow2 format, and a disk file of approximately 1.2T in raw format, mainly to restore RAW format

Background:Virt-manager is the primary tool for managing KVM virtual environments, and Virt-manager requires root users to use the tool in the default settings. When you want to host a virtual machine on a KVM hypervisor server, it is not always convenient for the end user to access these virtual machines, rather than the root user.In some cases, this problem can be easily avoided with some virt-manager set

There are two methods to configure the KVM network. First, the default mode is usermode networking. packets are transmitted through the host interface in Nat mode. Second, with bridged networking, external machines can be directly connected to virtual machines, just like connecting to your host. I will focus on the bridging method and pass the test on ubuntu10.10. Mainly refer to the https://help.ubuntu.com/community/

:. Starting at v0.12, qemu-KVM has native support to VMware's Disk Images V6 (seems to be compatible with V7, used by VMware Server ). so VMware images can cocould be run with qemu-KVM without any modification (Make backups and do it at your own risks though !).
