p2v之 virt-p2v
|
virt-p2v的流程：
1、制作一个virt-p2v的启动U盘
2、找一台机器当做p2v的中转机器，用于第三步中，将物理机传输过来的数据进行转化（此转换机器启动了virt-p2v-server服务）。
3、将上述启动U盘插入将要进行p2v的机器（是指物理机）
4、启动插入启动U盘的物理机，开机启动选择U盘启动，通过网络，将物理机上面的数据传送给第二步的
virt-p2v-server服务
5、virt-p2v-server服务接收到数据，根据配置转换为相应的虚拟机文件

Virt-p2v converts a physical machine to run virtualized on KVM, managed by libvirt, OpenStack, oVirt, Red Hat Enterprise Virtualisation (RHEV), or one of the other targets supported by virt-v2v(1). Normally you don't run the virt-p2v program directly. Instead you have to boot the physical machine using the bootable CD-ROM, ISO or PXE image. This bootable image contains the virt-p2v binary and runs it automatically. Booting from a CD-ROM/etc is required because the disks which are being converted must be quiescent. It is not safe to try to convert a running physical machine where other programs may be modifying the disk content at the same time. This manual page documents running the virt-p2v program. To create the bootable image you should look at virt-p2v-make-disk(1) or virt-p2v-make-kickstart(1).
The reverse port forwarding feature of ssh (ie.
ssh -R
) is required by virt-p2v, and it will not work if this is disabled on the conversion server. (
AllowTcpForwarding
must be
yes
in the sshd_config(5)
file on the conversion server).
