There are multiple ways to skin most cats.
Hyper-V and VMWare and Xen - all of the hardware virtualization products - allow more diversity in your OS choice. Anything that your processor supports, you can pretty much run as a virtual. With OS virtualization, you can only run the OS installed as the host. That being said - I don't think that that really matters for most people. At least in hosting. When I go into a client that doesn't already have a virtualization solution chosen, I often will propose VZ if it fits the client's needs. Regards, Michael B.

Trying to determine if Virtuozzo is something that I want to spend some time with learning to support 2 or 3 clients total vs just letting someone else manage it. Its costs do seem to be a substantial. Let me ask a question then, what is the primary benefit of OS virtualization vs HW virtualization. They essentially both do the same thing, just two different underlying architectures.. Aside from single OS support per physical server any other why or why nots for VZ? HW virtualization you pay more in terms of performance loss than what VZ does.. So far it seems that the proc and memory mgmt in VZ is better than VMWare, so why would a company consolidating servers or looking for expansion go with VMWare over VZ if they are staying all on the same SW platform? From: Michael B. Smith [mailto:[EMAIL PROTECTED] Sent: Sunday, August 31, 2008 6:33 PM To: NT System Admin Issues Subject: RE: Virtuozzo Migration There are thousands of customers running Virtuozzo. Personally, I like it, and I like it a lot. I deployed it at my last job on quite a few servers. I could fire up a new server in less than 5 minutes with VZ. If you look at a hosting company providing VPSs (Virtual Private Servers), they are very likely hosting on Virtuozzo. The major upside of VZ is that it's extremely low overhead and you can overcommit memory and processor and it is very flexible - you can get 3x or 4x as many virtuals per physical server. The major downside of VZ is that all virtuals on a single server must be the same OS. It supports Live Migrations, cloning, snapshots, etc.etc. There is a OSS version of it, called OpenVZ. It's from SWSoft, who recently changed their name to Parallels. I personally see OS virtualization as a different product niche than hardware virtualization. OS virtualization fits really really well into hosting environments and into other environments that have very dynamic workloads that often need different performance profiles. Regards, Michael B.

I have been very upfront with my customer that Virtuozzo is not something I am 100% familiar with. I told him that I would be happy to offload this part of their server maint if they were more comfortable with that. They told me they would rather have me handle it however I chose, and they would defer to my judgment. 1. Is Virtuozzo a real contender against VMWare, I know the underlying technology is different but accomplishes the same goals and is it worth sticking out with? Customer is fine with costs to purchase or move to Vmware, but obviously would rather not spend money they don't have to. 2. What is the main benefit or disadvantage of moving to VMWare vs staying with Virtuozzo. HyperV is too new for customers confidence level at this point. 3. I have honestly only heard of 2 other businesses running Virtuozzo, and I don't believe I have ever heard it brought up on this list so I don't think it's considered mainstream. Just looking for opinions/options.

Standard version of converter and the ultimate boot cd are totally free. Vizion Core's product could be download free with only a couple of migrations allowed for trail purposes.

S From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Saturday, August 30, 2008 6:30 PM To: NT System Admin Issues Subject: Virtuozzo Migration We have a client in Miami that has a HP Server running Virtuozzo, the tech employed with the company has left and hence put them in a bind. The client is wanting to move to ESX. Anyone have some specific ideas for migrating from essentially virtual to virtual. Has anyone ever done the P2V tool from within a virtual server to a VMWARE ESX image? If not that then an Acronis image of individual servers and restoring directly onto VMWARE ESX?? I am in the process of setting up a test bed to do this, but obviously if someone has done it before and has any caveats that would be helpful.
