ubuntu16.04 Environment Installation KVM

1. See if the CPU supports virtualization
[Email protected]:~$ egrep-o "(SVM|VMX)"/proc/cpuinfo
Vmx
Vmx
Vmx
Vmx

2. Installing KVM and related dependency packages
sudo apt-get-y install QEMU-KVM
sudo apt-get-y install Ubuntu-vm-builder
sudo apt-get-y install bridge-utils
sudo apt-get-y install Virt-manager
sudo apt-get-y install Virt-viewer
sudo apt-get-y install Libvirt-bin
sudo apt-get-y install Qemu


3. Enable the KVM kernel module
[Email protected]:~$ modprobe KVM
[Email protected]:~$ modprobe Kvm-intel


4. Check whether the installation is successful
[Email protected]:~$ Kvm-ok
INFO:/DEV/KVM exists
KVM acceleration can used



5, after the installation is complete, the default is to enable the bridge network (Ifconfig can be viewed)
VIRBR0 Link ENCAP: Ethernet Hardware Address 00:00:00:00:00:00

If the bridging network is not enabled, then you need to enable a bridged network for the KVM virtual machine to connect, manually enable the method as follows:
Make changes to the/etc/network/interfaces configuration file
sudo vim/etc/network/interfaces

# enabing Bridge Networking Br0 Interface
Auto Br0
Iface br0 inet Static
Address 192.168.1.130

Broadcast 192.168.1.255
Gateway 192.168.1.1
Dns-nameservers 223.5.5.5
Bridge_ports eth0
BRIDGE_STP off

6. Open the KVM graphical interface manager
[Email protected]:~$ sudo virt-manager

7. To this end, the environment on which the KVM virtual machine is running is installed to complete the bird ...
