确认处理器是否支持KVM
egrep 'vmx|svm' /proc/cpuinfo
对当前系统做一个全面升级
sudo yum updatesudo yum upgrade
Installing
如果你不想安装Virtualization组，想单独安装需要的软件，可是使用下面命令
# yum install qemu-kvm libvirt virt-install bridge-utils
确认kvm已经安装
lsmod | grep kvm# lsmod | grep kvm kvm_intel 138567 0 kvm 441119 1 kvm_intel
Create the disk image
qemu-img create -f qcow2 disk.img 5Gor
dd if=/dev/zero of=disk.img bs=1G count=5# qemu-img create -f qcow2 disk.img 5GFormatting 'disk.img', fmt=qcow2, size=5242880 kB# dd if=/dev/zero of=disk.img bs=1G count=55+0 records in5+0 records out5368709120 bytes (5.4 GB) copied, 61.0353 seconds, 88.0 MB/s
Creating a virtual machine
/usr/libexec/qemu-kvm -hda disk.img -cdrom archlinux-2009.08-core-x86_64.iso -m 512 -boot d
如果你不在localhost上安装OS,你需要指定vnc,这样你可以远程连接到kvm
[root@scientific ~]# /usr/libexec/qemu-kvm disk.img -cdrom rhel-server-5.6-x86_64-dvd.iso -m 8000 -boot d -vnc :1
[root@scientific ~]# yum install -y virt-manager virt-top virt-v2v virt-vieweror[root@scientific ~]# yum groupinstall 'Virtualization'
