本文介绍了如何利用QEMU工具进行虚拟机环境的搭建过程，包括从ISO映像启动、创建虚拟硬盘、安装操作系统到虚拟硬盘中、启动带有多个虚拟硬盘的虚拟机等操作。此外还介绍了如何在网络桥接模式下启动虚拟机以及模拟多张网卡的方法。

Following are excerpted from Build appliances with QEMU and OpenBSD, BSD Magazine, 2011.04.

Boot from an ISO image: qemu -cdrom image.iso
Create new hard disk for a VM: qemu-img create disk.bin 2G
Install OS into the virtual disk: qemu -hda disk.bin -cdrom image.iso
Boot VM from virtual disk: qemu disk.bin
Boot VM with two virtual disks: qemu -hda first.bin -hdb second.bin
Start VM in bridge mode network: qemu -net nic -net tap disk.bin
Simulate multiple network cards: qemu -net nic,model=lance -net nic,model=pcnet -net nic,model=rt18139 disk.bin
QEMU can also be used with remote machines without X in -nographic mode. For this you have to have this in boot.conf(FreeBSD):
