Hi, till now I don’t know about virtualization. But after reading, I have some doubts.
Suppose I am running windows XP. I want to run red hat linux 5 also. I think there are two ways of running it. With virtualization and without virtualization. Without virtualization, I will just have to install Red hat linux 5 on another diskdrive. But I can’t run RHEL5 and XP concurrently, like I can do in case of virtualization.In virtualisaiton, I will have to install a virtual machine( i have heard of Microsoft virtual server) on windows. After installing the virtual machine software, how do I install Red hat linux 5. This is exactly my doubt. Thanks in advance.

Thanks for a great article…. it will really help me to build a better virtual environment.

The information about Bochs is not quite correct. It only runs X86 guest operating systems which excludes MorphOS and AmigaOS4 which are PPC (won’t do older AmigaOS either which were 680x based). There are Bochs ports are available for these theoretically allowing someone (with PowerPC hardware) to run X86 guest software such as Windows XP etc.

As for PowerPC emulators the main one that I know of is PearPC which should emulate OSX (PPC Version), Darwin and LinuxPPC.

Great ideas and would like to add a spanner into the works.

Has anyone tried install a single instance of KVM or Open VZ and then install multiple ESXi servers as guests on that server?
Why you might ask? One piece of hardware running multiple ESXi hosts, local storage is quicker than NFS or iscsi and you redundancy of the virtual machines!

Any takers?

@Charanjit,

RHEV == KVM and nothing else. It will take some time. Vmware and xen is hot right now.

Hi Vivek
Now days RHEV (Red Hat Enterprise Virtulization) I am hearing. What about your idea about it do you think it will compete with existence enterprise virtulization products such as Citrix Xen and VMware ESX. Do you think this will attract RHCE engineers to choose this product for their career.

I’m searching for PowerPC virtualization software, to be able to test Linux builds inside another Linux or Mac OS X. But it looks like good PPC virtualization has not yet made by anyone (mac-on-linux died, mac-on-mac is still alpha).

I have one specific requirement. Which virtualisation software will allow me to access the PCI cards .

Minor correction: VirtualBox was developed by Innotek, which was then purchased by Sun Microsystems.

i have only using virtual box. last release i guess is make me more comfortable allowed ping from nat guest and host interface configuration make easy. Have a try hope you will enjoy…

You can import images as VirtualBox can use VMware images (*.vmdk) directly. See my post and comment section for video:

I tried VirtualBox, it is look faster than VMWare…..

How Can I move my guests OS from EXS to virtualBox???

JohnMc,
Thanks, I will try that before go to EXSi. Thanks again.

Nice compilation I am currently using virtualbox for running some Windows apps in Linux.

I like VMware, but I am having some problems with the web management interface from time to time in VMware server 2.0. For some reason I have been having issues connecting to my VMs from the web interface, I get errors and I cannot seem to find the reason behind it. However I can VNC and ssh to the bridged interfaces, but it can be hassle a to get to the back end machines that are connected to my NAT and host networks. OpenVZ is kool, but it can be a pain to set up, but once set up, it is fantastic. Still needs work on making the administration a little easier, but I have had good success with it.

Couple of notes:

Too bad you did not mention Proxmox VE (Link). Rather unique in that it supports both OpenVZ containers and KVM virtualization. Nearly all management is via a web front end. Out of the download it also supports clustering and movement of VMs within the cluster. I have had several installations running for well over a year and not a peep of trouble.

Sudanking,

I actually do what you want (apaches, vpn, etc on different guests) using VirtualBox. I run a small script to set up the TAP/TUN networking then run all the guests with host mode networking. It works quite well. Running several instances of Ubuntu, Red Hat, etc in this manner eats up resources faster than doing so with something like OpenVZ containers however.

I mitigate that by running something like DSL or Slitaz in memory as a guest then save the instance state. I do not have to set up a virtual drive (VDI) in VBox though I run the risk of losing state if I forget to save it properly. So for about 256mb of memory per instance I can run Apache, VPN, etc and do all the testing I need. Its a great workaround, setup/teardown is very fast and the whole affair is no cost. I run the host and upto 4 guests in this manner in under 2Gb memory on a AMD 64×2 dual core box.
