Just wanted to Know if there are any Virtualisation Experts in Sajha?Wanted to Know which Virtualisation technology they r using...

Please give me complete information what exactly you are looking for or whats ur problem?

We have been testing Vmware ESX with EMC san for our enterprize for a while now. Yes , your requirement doesn't seems to be clear. There is very thin line between SAN, NAS, ISCSI-SAN these days. So, got to be clear what exactly you wanna do and are also highly dependent on the line of product. So,  if you are a bit specific about your design and requirement,,may be i could help you.

Your question is not that clear. Are you new to the field and want to know what are the product and services that are available in the market or just want to test if you are the only person to know virtualization here at sajha. Your question is not clear as other members have mentioned.

If you want to know about my environment I am using vmware on my vista machine at home. I have debian, solaris, redhat, mac os x, windows 2008, ubuntu, suse and on the other hand I am using solaris sparc system using zones and containers. I am also using LDOM on sun sparc T series processor.

If you mention what you really looking for I think you will get solid answer here.

"Are you new to the field and want to know what are the product and services that are available in the market ?"

Guys nd Gals?? Any info ? 

Xen should handle this scenario. As per your requirement, it looks like 20 VMs will share memory from 8GB memory pool. If the processes (in Xen instances) are memory intensive, then its going to be a real problem. Adding 12G of memory should not cost that much these days.

I haven't tried booting off the NFS. But there is a work around in Xen. You might have to rebuild kernel.

btw, how many cores do you have on the base machine?

It's a Quadcore machine..M$Hacks buying memory is not a problem but i looking for Cost effective(My company is ready to buy MEM's if i need to but I just think there has to be Workaround) solutions..Are U talking abiut Redhat with XEN,XEN Citrix or XEN running on Fedora core 5(The most stable instance i have found)..Running 20 Virtual Machines(Each with 1 GB Memory) sharing 8 GB pool of Memory is Interesting proposition..Isn't it?

It was on Debian Etch. My guest OSes were *nix based, both 32 adn 64bit. I have run M$ XP on Parallels and VirtualBox but not the Win 2008.

Since you are booting off the NFS, you can use try backing up the NFS share. Why do you think backing up the VM is problem? or were you talking about cloning the VM??

**Personally, I would not run 20 guest OS on a machine with a quad core ; ).

My $0.2.

I was "talking about cloning the VM"..Few Minutes ago found the Solution too..

i believe if you go down to ESX-3.0/ESX-3.2/3.5 you will have everything you need. 

"creating vm is not the big problem in your case"

this might help you?

"Just testing Webservers doesn't tax the system, so I am not sure why how you established your requirements."

thnks. giuys Esp M$hacks and Thapap..Thanks for ur contribution....I solved th Problem..The Answer is VMWARE cluster..

BTW pyaradeshbasiharu, what did you go with? just curious...

Vmware Esxi 4.0..

pyaradeshbasiharu,
I am glad that you you resolve your problem. I was missing from this forum but I was not good resource for your issue though. I am not good at Vmware Esx. I have only used free vmware server and workstation (which is not free though). I haven't use Linux lets say x86 platform for a while. I am mostly working on Solaris. If you enounter any problem with solaris please post it here and I will do my best to help you out.

Looks like there are couple of folks who are working on UNIX/Linux field and we can create a group or something to discuss about it. Why don't one create a Nepali Linux community. If there is one please share.

Thanks
