Remotely perform a KVM virtual machine installation

Using the following environment, measured by:

Virsh version:

Compiled against Library:libvirt 1.1.1

Using Library:libvirt 1.1.1

Using Api:qemu 1.1.1

Running Hypervisor:qemu 1.5.3

OS version:

Red Hat Enterprise Linux Server Release 7.1 (MAIPO)

Network composition:
PC---> Console server (10.167.14.102)----> server (192.168.10.3)

A Linux system installation is required on the KVM on the server via the PC. The PC does not have direct access to the server, SSH to the stepping server, and then SSH to the server.

The steps are as follows:

1. Create a new hard disk image:

Qemu-img create-f Qcow2/var/lib/libvirt/images/test.qcow2 20G

2. After preparing the OS image file on the server, execute the following command:

2.1. Direct command line installation:

#virt-install--virt-type KVM--name=test--ram=4096--vcpus=2--os-type=linux \

--location=/root/rhel-server-7.0-x86_64-dvd.iso \

--DISK/VAR/LIB/LIBVIRT/IMAGES/TEST.QCOW2,FORMAT=QCOW2 \

--network bridge:brx \

--graphics none--extra-args= ' console=tty0 console=ttys0,115200n8 serial '

All settings are done through the command line.

2.2. Remote VNC Installation:

#virt-install--virt-type KVM--name=test--ram=1024--vcpus=1--os-type=linux \

--location=/root/rhel-server-7.0-x86_64-dvd.iso \

--DISK/VAR/LIB/LIBVIRT/IMAGES/TEST.QCOW2,FORMAT=QCOW2 \

--network bridge:brx \

--graphics vnc,password=123456

2.2.1. Displaying the VNC port used

# Virsh Vncdisplay Test

127.0.0.1:0

Shown as 0, this is not what we say in the traditional sense of the port, the actual port should be 5900+0=5900.

2.2.2. Use teraterm ssh to 10.167.14.102, and then set the trunk:

Local Port: 12345

Remote host: 192.168.10.3 Port: 5900

2.2.3. Using the VNC Viewer on your PC:

Address: localhost:12345

Password: NFVPOC

(If option->display, remove adapt to network speed and then lower the image quality)

* Some people are talking on the Internet
/etc/libvirt/qemu.conf
In the
#vnc_listen = "0.0.0.0"
Do not unlock the words can not release VNC port, I do not encounter, if the use of the above instructions are unsuccessful, you may try, but do not forget

Systemctl Restart LIBVIRTD make it effective.
