Add new hard disk partition to ubuntu guest

install by force after dpkg dependency problem

You can fix this by installing missing dependencies.
Just run the following command
(after you have run sudo dpkg -i google-chrome-stable_current_i386.deb).
sudo apt-get install -f
This will install missing dependencies and configure Google Chrome for you.

MBR or GPT

MBR works with disks up to 2 TB in size, but it can’t handle disks with more than 2 TB of space. MBR also only supports up to four primary partitions — if you want more, you have to make one of your primary partitions an “extended partition” and create logical partitions inside it. This is a silly little hack and shouldn’t be necessary

GPT allows for a nearly unlimited amount of partitions, and the limit here will be your operating system — Windows allows up to 128 partitions on a GPT drive, and you don’t have to create an extended partition

Fdisk does not work for gpt, currently. But parted does. Or you can just easily install gdisk.

Over 1.5TB (if drive is unpartitioned) or is UEFI it defaults to gpt, otherwise it defaults to MBR

Prepare a MBR partition table
         #list new hard disk device for MBR
         fdisk -l
         #Partition type has to be primary
         fdisk /dev/sdb
       

Prepare a GPT partition table
$ sudo parted -l

sudo parted /dev/sda

#MBR DISK
(parted)mklabel msdos 

#GPT DISK

(parted)mklabel gpt  

 (parted)mkpart primary xfs 0 100%
 (parted) quit

mkfs -t xfs /dev/sdb1



#verify the file system mounted
cat /proc/mount

#find all block devices
ls /sys/block

Mount swift disk automatically at system boot with Upstart script
$cat /opt/swift/bin/mount_devices

mount -t xfs -o noatime,nodiratime,logbufs=8 /dev/sdb1 /srv/node/d1

$chmod +x /opt/swift/bin/mount_devices

$mkdir -p /srv/node/b1

$chown -R swift:swift /srv/node

Next, create an Upstart script in the /etc/init directory called start_swift.conf with the following commands:

description "mount swift drives"
start on runlevel [234]
stop on runlevel [0156]
exec /opt/swift/bin/mount_devices

Creating the Log Configuration File

Create a configuration file named 0-swift.conf in the /etc/rsyslog.d directory. It will contain
one line:
local0.* /var/log/swift/all.log
Since we just created a script that will tell the system to log the all.log file in the directory
/var/log/swift, we will need to create that directory and set the correct permissions
on it.
This command will create the directory the log files will be created in:

mkdir /var/log/swift
You also need to set permissions on the directory so the log process can write to it. For
instance, the following commands do this on Ubuntu:
chown -R syslog.adm /var/log/swift
chmod -R g+w /var/log/swift

For security reasons, disable the temporary authentication token mechanism:
Edit the /etc/keystone/keystone-paste.ini file and remove
admin_token_auth from the [pipeline:public_api],
[pipeline:admin_api], and [pipeline:api_v3] sections.


The Identity version 3 API adds support for domains that contain projects and users.
Projects and users can use the same names in different domains. Therefore, in order
to use the version 3 API, requests must also explicitly contain at least the default domain
or use IDs. For simplicity, this guide explicitly uses the default domain so examples
can use names instead of IDs.

--os-project-name admin --os-username admin --os-auth-type password \



You can store virtual machine images made
available through the Image service in a variety of locations, from simple file systems to object-
storage systems like OpenStack Object Storage.

Configure Wireless Networking in Ubuntu via the Command Line

First, you need to install the relevant software. You need to have a wired connection at this point, otherwise this wont work.

sudo apt-get install wireless-tools wpasupplicant

If you are connecting to an open network, you wont need wpasupplicant. Next, you need to “bring up” (essentially this means activate) your WiFi interface. So, issue:

sudo ifconfig wlan0 up

Next, to make sure your wireless device is working as it should issue:

iwconfig
and then
sudo iwlist scanwpa_passphrase YOURSSID YOURWIFIPASSWORD

This will result in something that looks like this:

network={
ssid="YOURSSID"
#psk="YOURWIFIPASSWORD"
psk=fe727aa8b64ac9b3f54c72432da14faed933ea511ecab1 5bbc6c52e7522f709a

Disabling NetworkManager

According to this bug here's how to disable Network Manager without uninstalling it:

Stop network manager

sudo stop network-manager

Create an override file for the upstart job:

echo "manual" | sudo tee /etc/init/network-manager.override

sudo vi /etc/resolvconf/resolv.conf.d/base

nameserver 16.110.135.51

nameserver 16.110.135.52

sudo resolvconf -u

sudo without passwd

soauser ALL=(ALL) NOPASSWD: ALL

vi /etc/hostname

sudo service hostname restart

By default, the SSH server denies password-based login for root. In /etc/ssh/sshd_config, change:


PermitRootLogin without-password
to
PermitRootLogin yes
And restart SSH:
sudo service ssh restart

NeutronApiService

During the building of the NeutronApiService, the _run_wsgi function creates a WSGI application using the load_paste_app function inside config.py - which parsesapi-paste.ini - in order to create a WSGI app using Paste‘s deploy.

The api-paste.ini file defines the WSGI applications and routes - using the Paste INI file format.

The INI file directs paste to instantiate the APIRouter class of Neutron, which contains several methods that map Neutron resources (such as Ports, Networks, Subnets) to URLs, and the controller for each resource.
