Choosing a hypervisor product

Hi Folks

I need to move several VMs from the free VMware product and create about 10 more for software testing purposes.

So we just bought 2x new servers with 1x quad cores and 8gb ram each

We've got MS licencing via our partnership so I'm wondering whether to use that or to go with VMWare ESX (probably not as its too expensive) or one of the free ones like XEN or Virtualbox etc.

My initial thought is to put 5 or 6 vms on each server and use XEN, but is XEN up to the job ? and will it be problematic ??

We would like to be able to also run Mac OSX and a few flavours of Linux (prob debian, slackware, redhat/fedora)

What hypervisor product would you recommend and please let me have any thoughts surrounding the whole issue. --thanks

I would recommend VMWare ESXi (FREE) as your solution if you want to save money. It's free and is the same hypervisor as ESX without the service console, and functionality like vmotion, DRS, etc. If of course you want that functionality later you can just buy the appropriate software.

Sounds great - never heard of esxi or that there was a free vmware hv - will take a look now..

Will it still let me take snapshots and revert etc ?

thanks

lots of reading there, but i agree with za_mkh that ESXi may be what you need, provided there is no requirement for Vmotion, DRS, HA...

in response to your question, YES VMware ESXi can take snapshots of your virtual machines and roll back changes

ESXi supports virtualizing Linux Distros but not Mac OS.

VMWARE all the Way ... yes I am biased, but do like MS products generally but for Virtualization, VMware is the way to go! :-)

Looking around the web, it sounds like esxi wont boot a 64 bit windows VM without VT - does that sound right ?

I might be better off with free VMWare Server if thats the case - but I've tried working with v2 of that and the interface is awful and it seems really slow ??

I really need a free or low cost visor product that can sit on the hardware and support 64 and 32 bit vms of linux, mac and windows ??

folks - any comment on the 64 bit thing above ? if esxi can run 64 bit windows without vt then thats the way to go. thanks

to run 64-bit guests, it is necessary to have VT.

check this: http://kb.vmware.com/selfservice/viewContent.do?externalId=1901

what is your processor make & model? have you checked if VT can be enabled in the BIOS?

plqAuthor Commented:
Its a Q8200 quad core. I bought 2 of them cos I read somewhere that all intel quads support vt, but Q8200 does not..

BIOS has that disable bit thingy but nothing about VT, but there's enough websites out there with discussions covering Q8200 not supporting vt

What about Virtual PC 2007 - would that support a 64 bit guest ?

plqAuthor Commented:
OK I've done enough research now to know that NOTHING supports 64 bit guests without VT.

If you know different please let me know but I've checked out MS Virtual PC and VMWare and XEN and Virtual BOX - all the same story !

unfortunately there is nothing more to this, what you say is right 'nothing supports 64 bit guests without VT'

Thanks for helping - I'm gonna see if I can get a VT CPU for that motherboard.
