Red Hat and Virtualization
September 19th, 2011
Posted in Being the vendor of Linux, Red Hat would want that its customer should run its technologies on Linux but the customers need to run RHEV i.e. Red Hat Enterprise Virtualization management system on Microsoft windows. This concept has changed now as a result the management system has been re-written so that java applications would run on top of a Red Hat Enterprise Linux server. For authentication of work, RHEV supports Active Directory. It also allows opening up the source of PostgreSQL database. According to thadani, the newly upgraded RHEV provide zero-downtime up-gradation. This updated windows free management would not cost you anything extra than what has been charged previously. They also let you know about the reason for which you will pay for i.e. enterprises needs to count the CPU sockets on the basis of the number used by them and accordingly they will be paying for the same.
The best part would be that Red Hat charges you one-seventh of the cost of VMware. Due to the addition of the new management server, we can come across a big change in the new version of KVM i.e. RHEV 3.0. This new version is simply hold to power the solution as a core virtualization hypervisor. The underlying hypervisor has been replaced with new KVM which is about to ship in RHEL 6.2. Along with this new up gradation, they have also considered performance enhancements which includes various features such as:-
- Transparent Huge Pages for database performance,
- paravirtualized interrupt controllers,
- a sync I/O
- An entire rewrite of the networking infrastructure.
They have also explained that the stack of the network has been moved from user to kernel space so that it can deliver better performance. Another most important feature of this system is that it can scale up to 128 CPUs with 2 TB of RAM at the host level providing for large virtual machines. It also provides built-in reporting infrastructure which help to leverages an embedded Jasper Reports engine. This engine provides historic views on usage and management so that it becomes easy for the users to manage the system.
Therefore, we can conclude the fact they have succeeded in grabbing more and more customers across the industry segments which has made RHEV 3.0 available in beta. It has been observed that Red Hat customers including major players like Qualcom, BNP Paribas and DreamWorks use RHEV.
Features of Hyper-V Virtualization
With latest upgrades regarding virtualization, Microsoft has always surprised the market experts. Recently, it has again occupied the market with the help of their new release of Windows Server 2008 virtualization technology Hyper-V that too before promised date. They had also made it available on their website i.e. now you can download Hyper-V beta provided your system is updated with the current x64 beta version of Windows Server 2008. The company admits that it has been designed in such a manner that hyper-V would be able to directly work within the environment of windows server and the same would make it easier for the users to implement and manage. Hyper-V has been launched by adding all the benefits virtualization-optimized microprocessors. This way it will help Microsoft to compete with other virtualization leaders who have already positioned their status in the market of hypervisor technology. Let us see what this technology is all about:-
In order to make your servers run multiple versions of different operating systems, hypervisors allow for cross-platform support. The management has explained that hyper-v has been designed in a manner that it can be set up within the windows server 2008 and can also be easily regulated as per the choice of the customers. The most new release of the operating system come with this feature of Roles because it will allow to set up only those roles which would be wanted by the customers to play in the environment of information technology i.e. IT. It has been mentioned that hyper-v in the virtualization market act as a criteria for horse race between two leader companies i.e. between Microsoft and VMware. In order to build virtualization into the operating system from Linux leader Red Hat Inc., Microsoft has come across a huge pressure as Linux leader was already adopted integrated cross-platform virtualization into Red Hat Enterprise Linux.
Therefore we can expect to see Windows Server 2008 in multiple editions which might be offered without Hyper-V or with Hyper-V. Microsoft has also come up with an idea of launching a product i.e. Microsoft Hyper-V Server which would take virtualization host environment into its consideration.
What do we mean by ‘live migration’
Microsoft has revealed a solution to one of the vital problem which has crop up in virtualization i.e. movement of an operational VM across WAN (wide area network). This solution is a latest release of Microsoft i.e. Windows Server operating system which shall be available in Microsoft’s Hyper-V version 3 hypervisor. The feature of this new release was made known to people at the Microsoft BUILD conference in Anaheim, California.
Within the virtual machines, there are certain applications which has made working VM move from one computer to another. This has been made possible with live migration and that too without any disruption. There are various software providers which allows you to avail live migration services within your local network but the challenge comes when live VM across different subnets, or separate WAN sub-networks. This concept has become difficult due to the complexities related to network latencies and network addressing.
Its working principle was explained so that it becomes easier for the users to make utilization of the same. Two internet protocol addresses has been provided for each virtual machine out of which one address is used as the home address for the respective virtual machines and it has been considered for communicating with the other net works. And in case it has been accessed publicly then communicate with the internet. Second address is basically allocated for the local data center. However this solution is made more effective with the use of Overlay Transport Virtualization (OTV) technology because it provides Cisco networking gear which makes the entire concept work for the purpose.
Features:-
- VMs can be saved on thumb drives or optical disks, and directing it to the new location so that the virtual machines can be updated incrementally with the latest changes.
- VM’s virtual hard disk can be migrated live with the help of this solution.
- This software can be scalable.
- In order to create virtual storage disk that too with a dimension of 16 TB in size, you can consider the usage of a new virtual file system called VHDX.
- This software would allow the system to support 32 virtual processors for every individual virtual machine and it also provides an appropriate memory size of 512 GB.
There are certain emergency situations where this release can be proved to be handy such as due to upcoming threat of flood or hurricane, if your data center is at risk then the software allows that the content might be moved to another facility. But as we know the moving of content depends upon the sizes of most data center-run systems as a result we have seen that only a handful of VMs can move at the same time.
Another appropriate situation would be permanent migration of systems. This means that without undergoing any downtime effect, this technology allows one data center to migrate to the next data center that too permanently. This would become most important for us when we would deal with data center consolidation projects.
Security Support for VMware Environments
In order to strengthen the partnership with VMware, the most renowned company called Sophos has announced increasing support for VMware vShield Endpoint. Sophos is well known for its data protection and IT security due to which it has gained a global recognition. This company has made VMware vShield Endpoint prototype as the part of its strategy of providing wider virtualization security solution.
This organization has struck a balance between virtualization and security as a result of which it has achieved maximum performance and at the same time managed to provide necessary protection against malware. On each virtual machine, the issue of physical footprint has been minimized with the effective endpoint security solution provided by Sophos. This can only be done by utilizing the ability to stagger scans and VMware memory sharing. It promises to deliver support for vShield 5 in its next release of security suite. But currently with the help of VMware vShield endpoint it allows to offload the anti-virus scanning to a dedicated scanner from the virtual machines.
They ensure their customers that when they will continue their journey with their virtualization and cloud computing system for upcoming years also then they can themselves experience the change rather the improvement in the security model provided by them which has been particularly designed to overcome the challenges associated with these dynamic environments.
This collaboration among two renowned organizations would be beneficial for their customers in a manner that now they will be protected against growing number of complex security threat so that it might not hamper your virtual and cloud environments. They have come up with this innovative idea because they understand that what challenge a company needs to face in protecting themselves against malware so that they might not come across data loss.
This does not event affect the performance level nor does it minimizes the cost benefits of virtualization. They always make sure that their customers must not face any negative impact of their inventions with respect to their work or cost savings as a result they offers you with broadest platform support covering physical and virtual environments. Their partnership would now allow the users to support the security of VMware environment. Therefore, we can say it help us to optimize the performance of virtual environment.
The Windows 8 Hyper-V
Hyper-V virtualization tool has been made accessible with windows latest version i.e. windows 8. It is a fascinating operating system for developers, IT pros, and other users who want to run, test, or support virtual environments. Previously it has been observed by the manager of the Hyper-V team named Mathew, that it was available with latest sever-based versions of windows but now for the first time Windows 8 has been launched as a client operating system which includes this virtualization features. But the question is how we can use this tool for our benefit.
With the help of these virtualization tools which offers various facilities such as running multiple OS and environments that too on the same machine, popularly used when people need to support and set up virtualized computers. It is very much important for the developers that they can easily switch from one environment to others that too without bearing an additional hardware costs. In order to run this latest version of operating system i.e. windows 8 Hyper-V, the users of the same would require 64-bit processor but it should be the bit version of windows 8 and in addition to that it must have RAM of at least 4 GB. It demands a bit system which must have SLAT i.e. Second Level Address Translation which helps you in managing memory.
In the current generation of 64-bit processor, SLAT is a feature which is available on almost every computer. Virtual PC is a tool which was offered by Windows 7 as its own virtualization tool. It was combined with window XP mode which allows the users to set up and run the applications of XP which was not compatible in case of Windows 7.
A robust virtualization tool has been designed called Hyper-V which provides you several benefits such as supporting non operating OS which is not possible when compared with windows virtual PC. We know that a virtualized environment requires allocating memory which is made possible with the release of latest version of OS. Multiple snapshots of virtual machines are allowed so that it might help the users to return to its previous virtual environment. This article would help you to know about windows 8 Hyper-V including its virtualization tool.
Importance of Linux virtual machine support
Linux support has been updated in the software of Hyper-V virtualization for Windows Server 2008 R2. When Linux virtual machines run on Hyper-V hypervisor then the software manages to improve relatively weak support. Hypervisor based virtual machines are basically those servers or operating systems upon which virtualization technology has been implemented.
Another name for hypervisor is virtual machine monitor which allows numbers of operating systems to run on a host computer. The best fact about the same is that it can mix various versions of Linux and Windows at the same time. The cost of the customers can be reduced and the continuity of the business can be improved as windows server 2008 Hyper-V provides an end-to-end virtualization platform. Microsoft has also launched the successors of windows server 2003 which is known as windows server 2008.
The most important feature of this new release i.e. Linux support is the support for SMP i.e. symmetric multi-processing which means that on every virtual machine, hyper-V can support up to four processors. In order to complete heavy back-end computation, SMP support plays a vital role in the virtual machines. Even though multi-core processors were prevailing but inclusion of support was not made sooner and later other improvements were also included such as time synchronization between host and virtual machine, failure detection, and improved performance. The performance can be easily improved by supporting Fastpath Boot.
The virtual machines which run on Novell SUSE Linux Enterprise Server 10 SP3, SUSE Linux Enterprise Server 11 and Red Hat Enterprise Linux 5.2 up to 5.5 are provided with support of Linux. In spite of such appealing features in Linux support, it was still far behind its competitors and as a result Microsoft Company felt the need of improvising the effect of the existing Linux support for virtual machines.
It appeases the Linux community which has threatened to remove support for Microsoft’s Hyper-V in the standard Linux kernel. Therefore we can say Microsoft Company provides a broader scope of opportunities so that their customers can achieve success at a continual rate.
Concept of NxTop 4
The concept of NxTop 4 has been released by virtual computer. With the help of this new release, both the centralized and distributed storage options are offered with desktop virtualization solutions. This allows the customers of virtual computer to store all their data in the data center by combining the network-based storage with the client-side hypervisor which is being stateless. At the price of server-hosted VDI, you can experience the feature of high-fidelity in desktop.
Lenovo has launched the underpinnings of this technology in the year 2009 which has been extended by the virtual computer for delivering NxTop. This technology has offered the highest performance that too at a low cost platform of desktop virtualization. With the help of Lenovo customer factory install or the global channel partners of virtual computer, it has become possible to make it available immediately.
Two tiers are included in the technology of NxTop i.e. NxTop Client and NxTop Center. The former tier is a client hypervisor that too Xen-based whereas the later tier is the component of centralized management. In the workstation edition, you can easily avail the features of NxTop hypervisor with an additional solution of centralized management. This is a scaled down version of the platform by which you can extend your accessibility to a maximum of five managed computers.
The salient features can be summarized as under:-

The NxTop 4 which is a new release and looks like a boon to the IT professionals. It remains to be tested and seen how far it actually helps end users.
Significance of Parallels Desktop 7.0
Parallel desktop 7.0 has been released with the addition of the best virtualization solution which can be well put into use for OS X. In order to make this newly released product run under lion, it has been designed with various unique features. With the modification in the end-user license agreement of the operating systems of desktop, the latest release has been given a new feature which enables to create virtual machines so that the client version of lion can run itself. For all users who want to run multiple configurations simultaneously, this is great for them. The example of multiple configurations can be developers, systems administrator, and, of course, journalists, reviewers etc.
The front end of parallels can be easily managed with the help lion compatibility. This can be explained with an instance like windows can be run in the new full-screen mode of the operating system so that the entire screen can be taken over effectively by the guest operating system. In order to run like the counterparts of the OS X, Windows applications are included in Mission Control and Launch pad. The parallel desktop comes with significant improvements i.e. their apps can simulate hardware that too up to 1GB of video memory so that higher resolutions can be easily handled.
This also allows 3D performance which is around 45 percent better than its predecessor. It is 60 percent faster in making start, stop and resuming windows when compared with its previous versions. This new release enables the company to promote it as an improved version of its iOS app which is basically used for controlling virtual machines running on OS X or Windows. You can experience this new version of desktop at the price of $80. This latest version of parallel desktop requires OS X 10.7 Lion as criteria to operate. It can be easily upgraded by the existing customers directly from the products website for $50. Therefore, we can say that it has been improved with copy and paste support, audio, and other new features.
