I heard some people said that Virtouzzo will simulate OS instead of simulate hardware.
Is that the reason why Virtouzzo faster than ESX based on that benchmark result?

Thank for the clarify. It seems that EULA is very tricky. It don't care to read it before until now I release that it very important.

Entirely possible. Remember, Virtuozzo virtualizes the OS, whereas ESX virtualizes the entire hardware platform. Each approach has its benefits and drawbacks.

The primary drawback to the Virtuozzo platform is that EVERY VPS has to be running the exact same OS - version, service pack, and patch level. ESX gives you the freedom to install and run any OS mix you want...

Can this help Microsoft to promote their product?
If so, why does M$ brave enough to do that?

Hi, ilyabm
Sound interesting, but have u ever used ESX before.
What are the major advantage/disadvantage you can notice between both of them?

PS: Just noticed that if you search "Virtuozzo VMware ESX".
This thread will show up as the first result.

It's seem to be hot right?

Then I guess VMware has no single policy for it. I have heard of other deals on this as well. They probably have several models based on the size of your hosting solution, etc (guessing). These things are not public so I guess one have to cut the deal with VMware directly if you want to do this.

IMHO it would serve VMware for the good to make a statement or release some official document on this topic. I can see a growing VPS market and I think VMware would have it's place with VI3 there as well. Customers that compare the VMware EULA and the MSVS EULA might go for the latter product without comparing the technologies too deeply.

Yes, VMware Server might be the product that *we* compare to MSVS today, but users not too familiar with this technology might not. And MSVS seems to grow in functionality in VS2005R2SP1/VS2007, not that it would compare to ESX on all the fancy stuff, but it seems to do a lot of things that VMware Server can't (better API, dynamic allocation of resources, excellent marketing, powershell, marketing, many good evangelists, marketing, good technet road shows, marketing, freep2v tool and good marketing.) And they probably don't loose many customers on giving that hosting statement as well. Especially now that ESX explicitly forbids it in the EULA and VMware server says nothing.
