Establish Ubuntu Virt Node

TurnToJPG -->

Just some tips on how to establish an Ubuntu Virt Node from existing installed system.

Re-Partition

2T Disk has been allocated to opensuse, thus I have first umount the mounted /home/ partition and use partition from yast for adjust the partition size, I got 1.9 T size of disk for installing new system.
Umount the mounted /home/ partition is via edit /etc/fstab file.

Install Ubuntu

Download the iso file of ubuntu x86_64 version, then enable kvm via:

$ sudo modprobe kvm
$ sudo modprobe kvm-intel

Install the system via following commands:

$ qemu-system-x86_64 -hda /dev/sda -m 1024 -boot d -cdrom ./install_media.iso

The above command is for installing the system into the real harddisk. It will automatically install the system onto the harddisk and over-write the MBR. Ubuntu will automatically detect the installed opensuse and generate the system description line.
In grub, the default system will be the installed ubuntu.

System Preparation

Install following packages:

$ sudo apt-get install openssh-server vim-gtk bridge-utils virt-manager git subversion sysfsutils virtualbox awesome firefox chromium-browser xinit libreoffice build-essential pidgin konsole meld  fcitx fcitx-googlepinyin git subversion wqy* zsh rox-filer smplayer cmake scrot thunderbird midori gpicview docker.io  qemu qemu-kvm bridge-utils

Configure the network via following command:

$ sudo brctl addif br0 eth0
$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet manual
# If you want to enable the static, uncomment following
# iface eth0 inet static
#       address 192.168.0.119
#       netmask 255.255.255.0


# Add Bridge Interface
iface br0 inet static
address 192.168.0.119
netmask 255.255.255.0
gateway 192.168.0.236
dns-nameservers 114.114.114.114
bridge_ports eth0
bridge_stp off
auto br0

Restart computer and now you got br0 enabled.

Install QQ:

$ sudo vim /etc/apt/sources.list
deb http://ppa.launchpad.net/lainme/pidgin-lwqq/ubuntu trusty main 
deb-src http://ppa.launchpad.net/lainme/pidgin-lwqq/ubuntu trusty main
$ sudo apt-get update && sudo apt-get upgrade
$ sudo apt-get install pidgin-lwqq

Now you could use pidgin for chatting.

Install xlockmore for using xlock locking screen:

$ wget http://packages.ubuntu.com/precise/amd64/xlockmore/download/*xxxx.deb
$ sudo dpkg -i xlockmore_package.deb

Disable UTC time via:

$ sudo vim /etc/default/rcS
# assume that the BIOS clock is set to UTC time (recommended)
UTC=no

Configure ZSH:

$ sudo vim ~/.zshrc
# For setting zsh history
HISTFILE=$HOME/.zsh_history
setopt INC_APPEND_HISTORY
setopt SHARE_HISTORY
HISTSIZE=5000
SAVEHIST=5000

Now the history file has been created and you could navigate between command history.

Quick setup for capturing picture:

$ cat /usr/bin/mycapscr 
scrot -s '%Y_%m_%d_%H_%M_%S_$wx$h.jpg' -e 'mv $f ~/capscr/'
$ mkdir -p ~/capscr

Now we got the standard development environment ready.
