[orcking]

I just signed up with turnkey Internet for a Virtuozzo VPS package
2GB RAM
20GM Hard drive
2.4GHZ CPU

Here is what I have noticed playing with the VPS for 2 days:
-not possible to have a paging file (limits programs to 2GB max)
not good if I want to use SQL Server standard edition

-the VPS lags sometimes, ex: launching firefox, not sure if this is related to Virtuozzo or the server is overloaded, the restarts are too slow, and the Remote desktop is kind of slow.

- I have had a dedicated server experience and the response was faster.

-My understanding is that memory could be a total of both Physical and page file with Virtuozzo (so 2GB could be disk and physical).

I have been reading about Hyper-V and my question for you guys is: does Hyper-V allow real paging?
is it faster than Virtuozzo( Hyper-V does hardware virtualization versus software by Virtuozzo)

any one using Hyper-V can give me some input..?

should I move to Hyper-V

and in Hyper-V when they give you lets say 1GB RAM , is it real physical RAM??

what is a good host for Hyper-V

Thanks

Poundhost offers Hyper-V VPS.

I think running SQL Server on VPS is not that good decision.

Virtuozzo and Hyper-V are two different animals. Virtuozo virtualizes the OS while Hyper-V (and VMware, etc) virtualizes the physical server. The VZ server requires only a single installation of Windows, while on the hyper-v server each virtual server requires its own windows installation (and license).

Not sure if this accounts for your performance issue

yes I have read about both..

umm, has any one experienced automatedvps.com???

they have Hyper-V

so it looks like Hyper-V should be faster, it doesn't run on top of the OS....

right?

Since Hyper V based on hardware level virtualization, it can not provide brustable RAM feature. It can only be possible using OS level virtualization like virtuozzo. So I think you will get real physical RAM with Hyper V.

I have experienced both virtuozzo and hyperV.

One thing i noticed with virtuozzo is that the windows virtual servers dont support things like shadow copy volumes and native windows backup.

Hope that helps this discussion.

I have been using hyper-v for awhile now and I think it's pretty good. The ram, as mentioned above is not burstable because it's hardware level virtualization. The snapshots are applicable while in live conditions, duplication so far is only when the vps is off. There are a ton of features that haven't been utilized in a panel enviornmet but the best I have seen thus far is dot net panels' hyper-v expansion.

I can vouch this. We have been offering Hyper-V for quite a few months now and it works great. On a well managed host server with ample resources, you will be able to have very good performance and high level of isolation with Hyper-V. Also DNP's integration with Hyper-V is decent as well... Though there are certain issues that needs to be taken care of fairly soon; we can be certain that its something long term.

I have some Virtuozzo servers (hosts), and the density is quite astounding. However, I believe the RAM is always 'RAM', and never 'Page File'. You also lose some advanced networking functionality (try running a VPN server, you won't get very far).

In both cases, the usual performance culprit is disk IO. If your VPS is laggy, that's likely what's going on.

Also, I've noticed that Virtuozzo sometimes has issues with the paged pool becoming full, since the host OS is often seeing several thousand independent processes, and that can lead to instability.

Hope that helps some!

We offered Virtuozzo VPS for over 2 years and Hyper-V for the last 12 months or so. The basic differences:

Virtuozzo: Shared OS, Shared RAM. Some issues installing exe's which interact with the underlying Windows OS. Great for running a web server, FTP etc. Can also run MSSQL 2005 without issues as long as you have enough RAM. Your virtual RAM is made up of physical and paged RAM. Can't use page file on the VPS. Great control panel features via Power Panel.

Hyper-V: More expensive and more like a dedicated server. Dedicated RAM and OS. Can install anything that you can install on a dedicated server. Can't over sell Hyper-V. Hyper-V more suited to enterprise usage where budget isn't such a concern.

In theory Hyper-V is more stable as you aren't sharing and there are less issues with the software that it runs on. Virtuozzo 4.x is very stable also but there can be issues when the host updates the base Windows OS with Virtuozzo updates. Usually Virtuozzo is restricted to a 64 bit OS to maximize server return.
