Running an instance in Openstack
I have to delete the "demo" "private" subnet that came with openstack-packstack to make the following steps work.
# login as openstack ID
# Source credentials file
source keystonerc_admin
# Create private network
neutron net-create private
# Associate subnet
neutron subnet-create --name private_subnet private 10.0.0.0/24
# create router
neutron router-create myrouter
# uplink router to the public internet
neutron router-gateway-set myrouter public
# uplink subnet to router
neutron router-interface-add myrouter private_subnet
# create security profile for jump host
neutron security-group-create jumphost
# Add rule to allow icmp in
neutron security-group-rule-create --protocol icmp jumphost
# Add rule to allow ssh in
neutron security-group-rule-create --protocol tcp --port-range-min 22 --port-range-max 22 jumphost
# find out net id

Install Openstack via RDO packstack
Please also refer here
These instructions are to install the current ("Icehouse") release.
Please name the host with a fully qualified domain name rather than a short-form name to avoid DNS issues with Packstack.
Step 0: Prerequisites
Software: Red Hat Enterprise Linux (RHEL) 6.5 is the minimum recommended version, or the equivalent version of one of the RHEL-based Linux distributions such as CentOS, Scientific Linux, etc., or Fedora 20 or later.
Step 1: Software repositories
Update your current packages:
sudo yum install -y openstack-packstack
Step 3: Run Packstack to install OpenStack
Packstack takes the work out of manually setting up OpenStack. For a single node OpenStack deployment, run the following command.
packstack --allinone
The installer will ask you to enter the root password for each host node you are installing on the network, to enable remote configuration of the host so it can remotely configure each node using Puppet.
The following is the output from my test server
# sudo yum install -y http://rdo.fedorapeople.org/rdo-release.rpm

These instructions are to install the current ("Icehouse") release.
Please name the host with a fully qualified domain name rather than a short-form name to avoid DNS issues with Packstack.
Step 0: Prerequisites
Software: Red Hat Enterprise Linux (RHEL) 6.5 is the minimum recommended version, or the equivalent version of one of the RHEL-based Linux distributions such as CentOS, Scientific Linux, etc., or Fedora 20 or later.
Step 1: Software repositories
Update your current packages:
sudo yum update -y
Setup the RDO repositories: sudo yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
Step 2: Install Packstack Installer
sudo yum install -y openstack-packstack
Step 3: Run Packstack to install OpenStack
Packstack takes the work out of manually setting up OpenStack. For a single node OpenStack deployment, run the following command.
packstack --allinone
The installer will ask you to enter the root password for each host node you are installing on the network, to enable remote configuration of the host so it can remotely configure each node using Puppet.
The following is the output from my test server
# sudo yum install -y http://rdo.fedorapeople.org/rdo-release.rpm

To use virtualization on Red Hat Enterprise Linux you require at least the
qemu-kvm and qemu-img
packages. These packages provide the user-level KVM emulator and disk
image manager on the host Red Hat Enterprise Linux system.
To install the
qemu-kvm and qemu-img packages, run the following command: # yum install qemu-kvm qemu-img
Several additional virtualization management packages are also available:
Recommended virtualization packages
- python-virtinst
- Provides the
virt-installcommand for creating virtual machines. - libvirt
- The libvirt package provides the server and host side libraries for interacting with hypervisors and host systems. The libvirt package provides the
libvirtddaemon that handles the library calls, manages virtual machines and controls the hypervisor. - libvirt-python
- The libvirt-python package contains a module that permits applications written in the Python programming language to use the interface supplied by the libvirt API.
- virt-manager
virt-manager, also known as Virtual Machine Manager, provides a graphical tool for administering virtual machines. It uses libvirt-client library as the management API.- libvirt-client
- The libvirt-client package provides the client-side APIs and libraries for accessing libvirt servers. The libvirt-client package includes the
virshcommand line tool to manage and control virtual machines and hypervisors from the command line or a special virtualization shell.
Install all of these recommended virtualization packages with the following command:
# yum install virt-manager libvirt libvirt-python python-virtinst libvirt-client
Installing Virtualization package groups
The virtualization packages can also be installed from package
groups. The following table describes the virtualization package groups
and what they provide.
Table 5.1. Virtualization Package Groups
| Package Group | Description | Mandatory Packages | Optional Packages |
|---|---|---|---|
| Virtualization | Provides an environment for hosting virtual machines | qemu-kvm | qemu-guest-agent, qemu-kvm-tools |
| Virtualization Client | Clients for installing and managing virtualization instances | python-virtinst, virt-manager, virt-viewer | virt-top |
| Virtualization Platform | Provides an interface for accessing and controlling virtual machines and containers | libvirt, libvirt-client, virt-who, virt-what | fence-virtd-libvirt, fence-virtd-multicast, fence-virtd-serial, libvirt-cim, libvirt-java, libvirt-qmf, libvirt-snmp, perl-Sys-Virt |
| Virtualization Tools | Tools for offline virtual image management | libguestfs | libguestfs-java, libguestfs-tools, virt-v2v |
To install a package group, run the
yum groupinstall <groupname> command. For instance, to install the Virtualization Tools package group, run the yum groupinstall "Virtualization Tools" command. KVM and virtualization in Red Hat Enterprise Linux
KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 hardware that is built into the standard Red Hat Enterprise Linux 6 kernel. It can run multiple, unmodified Windows and Linux guest operating systems. The KVM hypervisor in Red Hat Enterprise Linux is managed with the libvirt API and tools built for libvirt (such as
virt-manager and virsh). Virtual machines are executed and run as multi-threaded Linux processes controlled by these tools.
The KVM hypervisor supports overcommitting of system resources. Overcommitting means allocating more virtualized CPUs or memory than the available resources on the system. Memory overcommitting allows hosts to utilize memory and virtual memory to increase guest densities.
Thin provisioning allows the allocation of flexible storage and optimizes the available space for every guest virtual machine. It gives the appearance that there is more physical storage on the guest than is actually available. This is not the same as overcommitting as this only pertains to storage and not CPUs or memory allocations. However, like overcommitting, the same warning applies.
Kernel SamePage Merging (KSM), used by the KVM hypervisor, allows KVM guests to share identical memory pages. These shared pages are usually common libraries or other identical, high-use data. KSM allows for greater guest density of identical or similar guest operating systems by avoiding memory duplication.
The QEMU Guest Agent runs on the guest operating system and allows the host machine to issue commands to the guest operating system.
When several virtual machines are running simultaneously, they can interfere with system performance by using excessive disk I/O. Disk I/O throttling in KVM provides the ability to set a limit on disk I/O requests sent from virtual machines to the host machine. This can prevent a virtual machine from over utilizing shared resources, and impacting the performance of other virtual machines.
The libvirt package provides:
- A common, generic, and stable layer to securely manage virtual machines on a host.
- A common interface for managing local systems and networked hosts.
- All of the APIs required to provision, create, modify, monitor, control, migrate, and stop virtual machines, but only if the hypervisor supports these operations. Although multiple hosts may be accessed with libvirt simultaneously, the APIs are limited to single node operations.
The libvirt package is designed as a building block for higher level management tools and applications, for example,
virt-manager and the virsh command-line management tools.
The
virsh command-line tool is built on the libvirt management API and operates as an alternative to the graphical virt-manager application. The virsh command can be used in read-only mode by unprivileged users or, with root access, full administration functionality. The virsh command is ideal for scripting virtualization administration.virt-manager is a graphical desktop tool for managing virtual machines. It allows access to graphical guest consoles and can be used to perform virtualization administration, virtual machine creation, migration, and configuration tasks. The ability to view virtual machines, host statistics, device information and performance graphs is also provided. The local hypervisor and remote hypervisors can be managed through a single interface.Sunday, May 11, 2014

How to fix "invalid EFI file path" from dual boot EFI Windows 8 and CentOS
Problem : When trying to dual boot to Windows 8, "invalid EFI file path" error is displayed
Reason : CentOS grub did not find Windows 8 EFI correctly
File needs to be modified : /boot/efi/EFI/redhat/grub.conf
Before :
title Other
rootnoverify (hd0,4)
chainloader +1
After :
title Windows 8
root (hd0,1)
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
Although (hd0,4) is where Windows 8 located (/dev/sdb5) , we should put where the file EFI/Microsoft/Boot/bootmgfw.efi is located. (hd0,1) is where bootmgfw.efi is located (/dev/sdb2)
After grub.conf is modified, it will boot fine.
[root@novo etc]# df -k /boot/efi
