>IIRC, GSX is Linux with custom kernel modules but ESX is it's own kernel. I think it was based on FreeBSD way back when they founded VMWare.. no idea if they pull things from the FreeBSD of today. GSX can run on Windows 2K+ or Linux AFAIK. ESX runs a cutdown version of what appears to be Redhat 7.x Also, GSX seems to run on almost any hardware while ESX was VERY picky about what it ran on - it only runs on SCSI disks BTW... I have installed and used both ESX & GSX and they are VERY impressive products. I was told by the VMWARE rep that a VMWARE virtual machine could be moved "on-the-fly" across a SAN without shutting it down! Haven't tested this yet though!

Only realised after I started with EMC that we had purchased them sometime before I started. In any case, our Sydney Lab uses several Dell servers running VMWare ESX to run several virtual machines for lab testing and stuff. Works great. I've been a big fan of VMWare from the earlier days, since it just worked so well. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Broun, Bevan wrote: I think you will want vmware esx which installs straight on your hardware. I used to work at VMWare. All the new features (especially performance features) went into ESX before they went into GSX and sometimes filtered down to Workstation. It's a little known fact that VMWare actually writes their own kernel, specifically for running virtual machines. I remember that page sharing and fair scheduling was the two major advantages of ESX. Don't know how much has changed since back then. Trent -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
RE: [SLUG] Virtual hosting with VMWare
Thanks for that! I see VMWare company is now part of EMC. Since I suspect we are going to be using an EMC SAN system, I think that will be OK. VMWare ESX seems to only support up to RHEL3 as a guest OS. By that I mean "officially support", in practice all sorts of things would probably work. OK, lots of reading for me to do!

[SLUG] Virtual hosting with VMWare
Title: Virtual hosting with VMWare Hi all, I am starting to design a virtual server system for internal work. The one piece of hardware would need to host a couple of RHEL4 virtual servers (one primary, one for application test & development - mainly Apache), and possible a couple of Windows servers (for old applications). I'm thinking of using VMWare and not sure what the base host OS should be at this stage (could be RHEL3,4 or even Win2003 just to annoy me). The hardware would need to be able to connect to a FC SAN. I would imagine it would need to be maxed out for RAM to accommodate all the virtual hosts. Dell has some hardware which should be able to do this. Has anyone had any experience with doing something like this? If so, how did you organise installing patches and updates on the base host? On the virtual hosts? How did you find VMWare coped with the varying loads from the virtual hosts, compared with running separate physical hardware? Does adding a TOE (TCP Offload Engine) vastly improve the end-user response time? Happy to hear any comments, Regards, Jill. -- Jill Rowling, System Administrator Eng.
