1. First, I use vmware workstation to create a centos7 virtual machine, and then turn on virtualization, as shown in the following figure.
2. Start the virtual machine and check whether virtualization is supported
[root@template ~]# cat /proc/cpuinfo | grep -E 'vmx|svm'
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts mmx fxsr sse sse2 ss ht syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts nopl xtopology tsc_reliable nonstop_tsc aperfmperf 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 epb tpr_shadow vnmi ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 invpcid xsaveopt dtherm ida arat pln pts

3. Again, check whether the kvm driver has been loaded,
[root @ template ~] # lsmod | grep
kvm kvm_intel 188416 0
kvm 581632 1 kvm_intel
irqbypass 16384 1 kvm
# If the kvm driver is not loaded, use the command to load the driver
modprobe -a kvm
modprobe -a kvm_intel
4. Install qemu-kvm
yum install -y qemu-kvm
5. Install libvirt
yum install -y libvirt
[root@template ~]# systemctl restart libvirtd
#Verify whether libvirt starts normally
[root@template ~]
# systemctl status libvirtd

6、安装virt-manager工具
yum install -y virt-manager
7、自己的Windows pc 安装Xmanager
8、xshell 工具File--->Properties，如下图所示
9、万事具备了，用xshell工具连接centos服务器，执行命令virt-manager, 呀，乱码
破解乱码的解决办法为安装virt-manager字体：
yum install dejavu-lgc-sans-fonts -y
10、在打开一个xshell窗口，再次执行virt-manager,一切ok了。
