Win10系统通过VMware安装Centos7 部署KVM安装WIN7虚拟机

Win10系统通过VMware安装Centos7,部署KVM安装WIN7虚拟机

一、环境准备

本机Win10系统

下载Centos7镜像，Win7镜像，VMWare软件，XShell软件，VNCViewer

二、安装Centos7系统

Win10安装VMWare

VMWare安装Centos7镜像

XShell登录Centos7

xftp将Win7镜像传入Centos7中

三、Centos7里部署KVM

1、验证是否支持虚拟化

[root@yzl ~]# egrep '(vmx|svm)' --color=always /proc/cpuinfo flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss ht syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon nopl xtopology tsc_reliable nonstop_tsc eagerfpu pni pclmulqdq vmx ssse3 fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm ssbd ibrs ibpb stibp tpr_shadow vnmi ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 invpcid xsaveopt arat spec_ctrl intel_stibp flush_l1d arch_capabilities。。。# 可以看见带有vmx，说明支持vmx虚拟化

可以看见带有vmx，说明支持vmx虚拟化。如果没有这个输出，说明你没有开启vmx虚拟化支持，所以，你需要在VMware虚拟机设置里，找到虚拟化引擎，勾选虚拟化Intel，就可以了。

2、装包

[root@yzl ~]# yum -y install kvm python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer virt-v2v libguestfs-tools# 安装VNC，后面连接安装用[root@yzl ~]# yum -y install vnc-server[root@yzl ~]# yum -y install tigervnc-server

3、启动libvirtd服务

[root@yzl ~]# /sbin/service libvirtd restart[root@yzl ~]# ln -s /usr/libexec/qemu-kvm /usr/bin/qemu-kvm

四、KVM安装WIN7虚拟机

1、安装virtio驱动

[root@yzl ~]# wget /groups/virt/virtio-win/virtio-win.repo -O /etc/yum.repos.d/virtio-win.repo[root@yzl ~]# yum install virtio-win -y# 网络yum源安装，时间较慢

2、搭建虚拟机

[root@yzl ~]# qemu-img create -f qcow2 win7.img 20GFormatting 'win7.img', fmt=qcow2 size=21474836480 encryption=off cluster_size=65536 lazy_refcounts=off [root@yzl ~]# echo $?0

创建虚拟机

[root@yzl ~]# virt-install -n win7 --vcpus=2 --ram=1024 --os-type=windows --os-variant=win2k12 -c /root/GHOST_WIN7_X64_C.iso --disk path=/usr/share/virtio-win/virtio-win-0.1.171_amd64.vfd,device=floppy --disk path=/root/win7.img,format=qcow2,bus=virtio --graphics vnc,listen=0.0.0.0 --noautoconsole# 命令解释# virt-install# 安装命令# -n win7 # 虚拟机命名# --vcpus=2 # 分配两个CPU给这台机器# --ram=1024 # 分配1024内存# --os-type=windows # 类型是windows# --os-variant=win2k12 -c /root/GHOST_WIN7_X64_C.iso #指向win7镜绝对路径# --disk path=/usr/share/virtio-win/virtio-win-0.1.171_amd64.vfd,device=floppy #指向驱动virtio-win-0.1.126_amd64# --disk path=/root/win7.img,format=qcow2,bus=virtio --graphics vnc,listen=0.0.0.0 #指向虚拟磁盘win7.img，默认端口5900# --noautoconsole

第一次安装，可能会有报错

[root@yzl ~]# virt-install -n win7 --vcpus=2 --ram=1024 --os-type=windows --os-variant=win2k12 -c /root/GHOST_WIN7_X64_C.iso --disk path=/usr/share/virtio-win/virtio-win-0.1.171_amd64.vfd,device=floppy --disk path=/root/win7.img,format=qcow2,bus=virtio --graphics vnc,listen=0.0.0.0 --noautoconsoleWARNING /root/win7.img may not be accessible by the hypervisor. You will need to grant the 'qemu' user search permissions for the following directories: ['/root']Starting install...ERROR Cannot access storage file '/root/win7.img' (as uid:107, gid:107): Permission deniedDomain installation does not appear to have been successful.If it was, you can restart your domain by running:virsh --connect qemu:///system start win7otherwise, please restart your installation.

提示无法访问，权限被拒绝。解决办法：更改/etc/libvirt/qemu.conf可以解决问题。取消注释用户/组以root用户身份运行。

[root@yzl ~]# vim /etc/libvirt/qemu.conf# 注释掉用户/组以root用户身份运行 两行# 修改完后，配置文件内容如下：[root@yzl ~]# grep -v "^#" /etc/libvirt/qemu.conf | grep -v "^$"user = "root"group = "root"[root@yzl ~]# systemctl restart libvirtd# 修改后重启虚拟化服务

再次执行，安装成功后，会有如下提示

[root@yzl ~]# virt-install -n win7 --vcpus=2 --ram=1024 --os-type=windows --os-variant=win2k12 -c /root/GHOST_WIN7_X64_C.iso --disk path=/usr/share/virtio-win/virtio-win-0.1.171_amd64.vfd,device=floppy --disk path=/root/win7.img,format=qcow2,bus=virtio --graphics vnc,listen=0.0.0.0 --noautoconsoleStarting install...Domain installation still in progress. You can reconnect to the console to complete the installation process.[root@yzl ~]# echo $?0[root@yzl ~]# virsh list --allId Name State-----------------------------------------------------win7 shut off
