How to install Windows 2008 R2 64bit Guest OS on Vmware ESXi 5.1


VMware: Installing a Guest Operating System (Windows 2008 R2 64bit) on Virtual Machine

Installing a Windows 2008 R2 64bit Guest OS on Vmware ESXi
Installing a Windows 2008 R2 64bit Guest OS on Vmware ESXi

You can install a guest operating system from a CD-ROM or from an ISO image. Installing from an ISO image is typically faster and more convenient than a CD-ROM installation.

It might be necessary to change the boot order in the virtual machine’s BIOS settings. However, sometimes a virtual machine’s boot sequence progresses too quickly for a user to open a console to the virtual machine and enter BIOS setup.

Right Click on VM -> Options Tab -> Boot Options -> “The next time the virtual machine boots, force entry into the BIOS setup screen”

 Windows 2008 R2 64bit Virtual Machine - Edit Settings- Boot Options
Windows 2008 R2 64bit Virtual Machine – Edit Settings- Boot Options

The virtual machine enters the BIOS setup the next time it starts.

 Windows 2008 R2 64bit Virtual Machine - Edit Settings- Boot Options - CD Drive
Windows 2008 R2 64bit Virtual Machine – Edit Settings- Boot Options – CD Drive

Or

1 Display the Virtual Machine Properties dialog box.

2 Click the Options tab and in the settings list under Advanced, select Boot Options.

3 Enter a delay value long enough to enable the console view to stabilize and for you to connect the CD-ROM using the vSphere Client.

4 Click OK.

5 Open a console to the virtual machine.

6 Power on the virtual machine.

7 While the virtual machine proceeds through its boot sequence, connect your local device, or an ISO image, to the virtual machine’s CDROM drive.

3 Options:

CD-ROM: Insert the installation CD-ROM for your guest operating system into the CD-
ROM drive of your ESX/ESXi host.

ISO image:

a Right-click the virtual machine in the inventory list and select Edit Settings.
b Click the Hardware tab and select CD/DVD Drive.
c In the Device Type panel, select Datastore ISO File and browse for the ISO image for your guest operating system.

User can use the option “VMware: Connect to ISO Image on Local Disk” also which is only available when VM is powered on.

Before Powering on the VM (Option Disabled)

Windows 2008 R2 64bit Virtual Machine - Connect to Host Device
Windows 2008 R2 64bit Virtual Machine – Connect to Host Device

After Powering on the VM (Option enabled)

Windows 2008 R2 64bit Virtual Machine - Connect to ISO image on Local Disk
Windows 2008 R2 64bit Virtual Machine – Connect to ISO image on Local Disk

And If you provide Windows 2008 R2 64bit ISO file then it will start:

Windows 2008 R2 64bit installation on Virtual Machine
Windows 2008 R2 64bit installation on Virtual Machine
Windows 2008 R2 64bit installed on Virtual Machine
Windows 2008 R2 64bit installed on Virtual Machine

Workflow Token Tab was empty; Events tab showed only 2 events 1) created & 2) saved. Inventory for those vCO plug-ins inside the vCO client works fine.

Verify the user which is configured for both plug-ins (it could be the same or not) has the rights to perform the operation of powering on a VM.

If no issue exist with permission misconfiguration then…??/

Check for error messages on the server.log file and it would certainly gives the reasons it is failing.

So now the Solution is: Disable the VIX plug-in in the web configuration and try again.

How to disable the VIX plug-in?

vCO configuration -> Plugins tab and uncheck that -> Restart the service or the server under the Startup tab -> Do it a couple different times to remove it from my inventory on the vCO client.

I removed the VIX plugin and all is working now.

what is OpenStack


what is OpenStack – OpenStack offers open source software to build public and private clouds started by Rackspace (“Cloud Files” platform) and NASA (Nebula) in 2010. Currently more than 150 companies have joined the project such as Intel, Cisco, Dell, HP, AMD, Canonical, SUSE Linux, Red Hat, and IBM.

There are 3 main service families under OpenStack:

Cloud Computing – Download Free EBooks and Whitepapers
Java – Download Free EBooks and Whitepapers
Windows – Download Free EBooks and Whitepapers

1. OpenStack Services

Figure 1: OpenStack Services

Presentation Layer: components here interact with users to accept and present information.

Logic Layer: intelligence and control functionality for cloud.

Resources Layer: Compute, Storage and Network Resources for Cloud.

Compute Infrastructure (Nova)

 OpenStack Architecture

Figure 2: OpenStack Architecture

  • Nova: cloud computing fabric controller
  • Instance life cycle management
  • Management of compute resources
  • Networking and Authorization
  • REST-based API
  • Asynchronous eventually consistent communication
  • Hypervisor agnostic: support for Xen, XenServer/XCP, KVM, UML, VMware vSphere and
  • Hyper-V [No virtualization capabilities by itself; instead, it uses libvirt APIs to interact with the supported hypervisors.]

Use Cases:

v  Service providers offering an IaaS compute platform

v  IT departments provisioning compute resources to teams and projects

v  Processing big data with tools like Hadoop

v  Scaling compute up and down to meet demand for web resources and applications

Storage Infrastructure (Swift)

Swift provides a distributed, eventually consistent virtual object store for OpenStack. It is analogous to Amazon Web Services – Simple Storage Service (S3).

  • Storage of large number of objects
  • Storage of large sized objects
  • Data Redundancy
  • Archival capabilities – Work with large datasets
  • Data container for virtual machines and cloud apps
  • Media Streaming capabilities
  • Secure storage of objects
  • Backup and archival
  • Extreme scalability

Imaging Service (Glance)

OpenStack Imaging Service is a lookup and retrieval system for virtual machine images. It can be configured to use any one of the following 3 storage back-ends:

  • OpenStack Object Store to store images
  • S3 storage directly
  • S3 storage with Object Store as the intermediate for S3 access

Image Management

OpenStack Image Services are used for discovering, registering, and retrieving virtual machine images. The service includes a RESTful API that allows users to query VM image metadata and retrieve the actual image with HTTP requests. VM images made available through OpenStack Image Service can be stored in OpenStack Object Storage project, S3 storage.

Instance Management

An instance is a virtual machine provisioned by OpenStack on one of the nova-compute servers. When you launch an instance, a series of steps are triggered on various components of the OpenStack.

OpenStack Instance Life Cycle

Figure 3: OpenStack Instance Life Cycle

Network Management

In OpenStack, the networking is managed by a component called “nova-network”. This interacts with nova-compute to ensure that the instances have the right kind of networking setup for them to communicate among themselves as well as with the outside world.

  • Flat Network
  • Flat DHCP Network
  • VLAN Network

Identity Service

The OpenStack Identity Service provides services for authenticating and managing user, account, and role information for OpenStack clouds running on OpenStack Compute and as an authorization service for OpenStack Object Storage.

Hypervisors Support

List of the supported hypervisors with links to a relevant web site for configuration and use:

  • Hyper-V 2008 – Use to run Windows-based virtual machines, specifically Windows 2008 R2 Datacenter or Enterprise Edition. You must install and run nova-compute on Windows servers that run the Windows-based virtual machines.
  • KVM – Kernel-based Virtual Machine. The virtual disk formats that it supports it inherit from QEMU since it uses a modified QEMU program to launch the virtual machine. The supported formats include raw images, the qcow2, and VMware formats.
  • LXC – Linux Containers (through libvirt), use to run Linux-based virtual machines.
  • QEMU – Quick EMUlator, generally only used for development purposes.
  • UML – User Mode Linux, generally only used for development purposes.
  • VMWare ESX/ESXi 4.1 update 1, runs VMWare-based Linux and Windows images through a connection with the ESX server.
  • Xen – XenServer 5.5, Xen Cloud Platform (XCP), use to run Linux or Windows virtual machines. You must install the nova-compute service on DomU.

Computer Network, Network Monitoring and Management

Figure 1: Computer Network, Network Monitoring and Management

Computers connected with communication channels shares resources and information with each other. Network monitoring supervises all or specific operations of computer network using various network monitoring products. It ensures performance and availability of network services by identifying and reporting failures of network services. Network management refers to the actions, procedures, and tools that are related to keeping network services up and running, keeping track of resources, performing upgrades, and configuring resources of networked systems. Network Management is a superset of network monitoring term.

In this article our focus will be on open source network monitoring and infrastructure monitoring tool known as Nagios. It provides monitoring and reporting for network services such as HTTP, SMTP, SSH, and FTP; host resources such as logs, storage and processor usage. It monitors IT infrastructure, detect the problems before they occur and alerts the stockholders. Web based GUI is available. It is also used to monitor publicly available services. It is very useful for SMBs.

Effective usage of it ensures issue tracking within timely manner; SLAs, which are very critical in today’s dynamic IT world, can be met effectively and it ensures that outages will have minimal effect on organization’s IT infrastructure as it monitors infrastructure extensively.

Nagios Core

Nagios Core is an open source, infrastructure monitoring system that enables organizations to identify IT infrastructure problems before they have an effect on critical business processes.

Nagios Core provides base for Nagios XI – commercial monitoring solution.

Nagios Core allows to monitor your entire IT infrastructure to ensure IT resources, applications, services, and business processes are functioning appropriately. In the event of a failure, it can alert technical staff of the problem in timely manner which allows them to commence remediation processes before outages affect business processes, end-users, or customers. It is licensed under GNU General Public License.

Use Cases

ISPs, Government agencies, Health care, Manufacturing, and financial institutions can use it effectively for network monitoring.

Banking and Finance Industry

It is desirable to have networking monitoring product which is easy to setup, configure and maintain. It must monitor different kind of devices and multiple platforms within adequate budget. Banking and financial industry deals with critical, time bound and monetary transactions which should be made available to customers all the time. Its alerting capabilities help banking and finance industries to decrease the downtime of various services within adequate budget due to its open source availability.

Telecommunication Industry

Telecommunication providers who use various application and system resources monitored by various network monitoring systems can use it to provide deep insight into the complex IT infrastructure. By using single solution in the form of Nagios, operational efficiency and cost benefits can be achieved.

Monitor openSUSE Virtual Machine

To run a Nagios core, you need a machine running Linux or Unix variant, Network accessibility as basic prerequisite.

We can use VMware workstation or VMware Player to create virtual machine; In fact any other product can be used also. Install openSUSE 12.2 operating system on the virtual machine as we will use that linux variant in the below steps. Insert openSuse 12.2 DVD and from VMware workstation, go to Edit Settings of that virtual machine to connect to the openSUSE DVD.

Prerequisite packages:

  • C/C++ development libraries
  • php5
  • apache2
  • apache2-mod_php5

We will use Zypper command to install prerequisite packages. Zypper is a command line package manager.  It uses libzypp and provides functions such as repository access, and package installation. Zypper RPM packages are by default available on standard openSUSE installation media and need not to install the packages manually. It can be used to install/remove/update packages or patches, and plain rpm files; it also provides detailed installation summary.

To install C/C++ development libraries:

zypper install kernel-source make gcc gcc-c++

To install other packages:

zypper install rrdtool php5 php5-gd php5-zlib apache2-mod_php5 perl-SNMP net-snmp-32bit nmap ncpfs libwavpack1 apache2

Cloud Monitoring with nagios

As per NIST’s definition, Cloud computing is a model for enabling

  • Ubiquitous,
  • Convenient,
  • On-demand network access

to a shared pool of    configurable computing resources

  • Networks
  • Servers
  • Storage

that can be rapidly provisioned and de-provisioned with minimal management effort. Virtualization is the core of Cloud Computing considering it provides, Cost saving by reducing upfront investment in infrastructure. In Virtualization, we create multiple virtual environments on a single physical resource by decoupling OS from hardware, create an abstraction between OS and the hardware and optimize resource utilization with the use of virtualization product.

When we say Cloud Monitoring, it is in the context of monitoring resources available in Cloud or provided by Cloud service providers.

In virtual world monitoring of resources is not only necessary but crucial also to provide high availability and fault tolerance, and to avoid single point failure since resources are shared. Monitoring of virtual system is dynamic cince the resources are vitual and can be treated in similar way to files. Reource monitoring for scaling up and scaling down is also critical considering the huge capacity (virtyally unlimited) provided by Cloud service providers.

Public Cloud Monitoring

Cloud monitoring refers to the monitoring of the performance of physical or virtual servers, storage, networks, and the applications running on them. Cloud monitoring tools are employed can collect data and illustrate patterns that might be difficult to spot otherwise in dynamic infrastructure and services provided by Cloud service providers. It used to achieve high availability.

Nagios provides monitoring of Cloud resources; compute, storage and network services. Nagios is proficient of monitoring a variety of servers and operating systems in both physical and virtual environment. We have seen an example where we have used Nagios to monitor virtual machine created in VMware workstation. With Nagios, it is easy to detect Cloud Computing environment issues, detection of network outages and application availability.

Benefits and Limitations

Implementing effective Cloud monitoring with Nagios offers multiple benefits:

  • High Availability: Increased server, services, and application availability
  • Fault Tolerance: Fast detection of network outages
  • SLA compliance: Fast detection of cloud computing environment problems
  • Data availability: Fast detection of storage subsystem problems

Amazon Web Services (AWS) Monitoring

Nagios provides monitoring of Amazon EC2, Amazon Simple Storage Services etc. Nagios solutions that provide Cloud monitoring capabilities and benefits are Nagios XI and Nagios Core.
