Technology : New Age Virtualization

In the hosting industry more than 100,000 customers are using virtualization technique VMware has been immensely appreciated world wide.

VMware has become global leader in virtualization solutions from the desktop to the Datacenter edition. Most of the customer’s from shared hosting environment have started using VSP as there basic needs, customers of all sizes rely on VMware considering the fact that it reduces the total expenditure and guarantees security freedom and reliability. VMware is a registered trademark of VMware, Inc. in the United State.

What next?

Windows Server 2008

Windows Server 2008 carries new functionality and prevailing improvements to the core. Windows Server operating system helps organizations of all sizes increase control, availability, and flexibility for their dynamic requirements Windows Server 2008 Virtualization technologies, security enhancements, and management utilities help to save time, reduce costs, and provide a solid foundation for your information technology (IT) infrastructure.

For customers that do not need virtualization, Windows Server 2008 Standard, Enterprise, and Datacenter editions are available without Windows Server Hyper-V Technology.

1. Limited to creating Certificate Authorities—no other ADCS features (NDES, Online Responder Service). See ADCS role documentation on TechNet for more information.

2. Limited to one standalone DFS root.

3. Limited to 250 RRAS connections, 50 IAS connections, and 2 IAS Server Groups.

4. Limited to 250 Terminal Services Gateway connections.

Microsoft has done a promising job with its Hypervisor, and it has just turned Linux freak into a Windows 2008 junkie for running his own personal virtualization needs. Proper implementation of Windows Server 2008 has resulted in a more secure, capable infrastructure that actually reduces the size of the data center and the resources required for operation that enhanced administration, security, IIS updates and virtualization promise to make improved networking and clustering.

Allocation of resources is the key deference between both the technologies. Virtuozzo, Xen , Open VZ allows equal distribution of resources that requires smart monitoring tools where as Hyper V 2008 data center edition divides the total RAM to the respective users as a stand alone performer.

What is HyperVM & how to install HyperVM manually?

I recently posted on How to install HyperVM using a Script, however missed out on one important thing. What is HyperVM?

HyperVM is a Web interface which helps you manage multiple Virtual Private Servers having its own Operating System. Also it has the option to link more than two HyperVM Servers to create a tree of Servers. These are just the Few features that I have mentioned.

Now lets get to the installation of HyperVM. This installation is done on Fedora Core servers and Xen Kernel. Also the Memory assigned will be dedicated. The advantage of using Xen rather than OpenVZ is that when there is a load on VPS it will start loading slowly in Xen and in OpenVZ it will crash instantly. Also remember that in Xen you have to restart the VPS every time you make changes in memory and hard drive space, whereas in OpenVZ its done instantly.

First you need to download HyperVM:

wget http://download.lxlabs.com/download/hypervm/production/hypervm-install-master.sh

Then you need to make the following changes in your Server:

1) disable selinux (edit /etc/sysconfig/selinux <– change to [SELINUX=disabled])

2) setenforce 0

3) chkconfig libvirtd off

4) reboot

How to install HyperVM:

1) cd DIROFHyperVM/

2) sh ./hypervm-install-master.sh –virtualization-type=xen

It might give you a error while installing HyperVm, in this case just rerun the command. Also if it says that HyperVm is already installed just click on Yes.

After the installation is done Reboot the Server and then:

1) SSH into the Server and enter the following folder cd /usr/local/lxlabs/hypervm/httpdocs/

2) Then Run the following Command:

lphp.exe ../bin/common/setdriver.php –server=localhost –class=vps –driver=xen

3) Then Once you are done go to a Browser and using the Server IP and Port 8887 or 8888 login to the Admin page. http://IP:8887 or http://IP:8888

4) The default username and password for HyperVM are “admin” and “admin”.

5) Then you need to add the additional IP’s on the Server to the HyperVM IP pool.

6) Then you need to go to the VM tab and then click on Add Xen, set the vm name and password.

7) Yos also need to select the number of Ip’s alloted, hostname of the Server, Gateway IP.

8) In case you have multiple HyperVm Servers you have the option to add which gateway the IP class is on and if you have only one then leave it as localhost.

9) Then select the OS to be installed and the Disk Quota.

10) Also you can select how many backups are allowed for the VPS.

11) Then you dont need make changes in the next three options as they are only for OpenVZ.

12) Then set the memory to be alloted to the VPS: 128 256 512 all in MB.

13) Then setup the CPU percentage to be alloted to the VPS: 10 20 25. The CPU quota also depends on the core of the server, for single core its 100% and for Dual or Quad it increases to 200%-400%.

14) Then allot the monthly Tarffic for the VPS: TRAFFICinGB x 1024

15) In the End you need to allot the number of IP’s, and check or uncheck if backup should be allowed or not.

16) Then click “add” and the HyperVm VPS will be added.
