I am looking to buy a new server and then run virtual servers for things like Exchange, VLE, print server, etc.
I have talked to a couple of suppliers buy i can't decide between VMware or Virtuoso.
I know nobody even got fired for buying IBM, but Virtuoso seems to have some benefits over VMware, like being able to swap images between severs of differring hardware specs.
Having looked at several threads i know some people are using VMware here, but is anyone using Virtuoso or can help me get off the fence... i'm getting splinters.
VMWare Server 1.0 is a non enlightened virtualation setup and will create a set of virtualised hardware which will be the same on any server.
If you have a look at the VMWare Server manual it will list the hardware that it emulates and the limitation on HW specifications within the virtual machines. ie a max of 3.6Gb of RAM.
Well thats what i hoped to do, but i've been led to believe (probably by people with a vested interest) that VMware requires identical server hardware on 2 or more servers to move images between servers.
I am unlikely to ever have 2 servers exactly the same so that would be an issue for me.
however, I have posted with the aim of being corrected, so thanks!
I had been looking at VMware ESX I think, if that helps?
Nah, VMWare itself doesn't give a fig what it installs on. We have it on a Xeon, a P4, A Sempron64, and several Core2's...the VMWare emulated PC remains the same, and they all run the images fine.
I personally use Virtualbox, because I find VMWare a tad bulky.
I agree too - VMware guest machines don't care what the host operating system is. I've moved machines between Linux and Windows quite happily.
I believe also you can have a 64bit host operting system and run 32bit guests although I've yet to try this - I need to do it now as ePortal needs more than 1GB to run well and I have two VMs on a 32bit windows machine.
Also the VMWare converter works well - this allows you to convert a real machine into a VM.
Abit of unrelated info but if you have Windows Server 2003 Enterprise you can run 4 virtual machines for free.
Also I have been told that Microsoft are interested in buying vmware.
There are some limitations to hot migration if you are moving the running machine between different chip architectures, I believe there is some vmware documentation somewhere explaining what can be moved around. Moving from 64 bit to 32 bit could be an issue, but this will apply to any VM solution that doesn't emulate the CPU.
Thanks for your help guys, i'm starting to realise how little i know about the whole area.
I know you can hot migrate these things also, but thats not the most important thing for me.
does anyone here actually run virtuoso?
