Which Desktop Virtualization software runs most sm

问题:

Background: I'm running a full-time job and a part-time job in the weekends, and both my employers have supplied a laptop for me to work on. Of course I also have my powerful workstation at home to work from, and sometimes when I'm at the office at my weekend job (it's in another city) I'm working from yet another workstation.

Problem: That makes a full 4 PC's I'm maintaining (software versions, licences and settings) just to do my work, and believe me, my list of prefered software is way too big.

I want to setup a Virtual Desktop on my VMware server, so I can work from the same installation and same session no matter which PC I'm working from.

Now I don't have the time and money to go through a full test of each setup, so I'd like to hear your experiences on the subject.

Question: Should I use a VMware virtual workstation with some remote logon software (like realVNC, teamviewer, logmein, whatever...) or should I invest in a full VDI system like Sun or VMware provide?

Edit: I'm programming in Adobe Dreamweaver on Windows XP - but I run my servers on Debian and sometimes do quick edits in VIM too. First I intend to virtualize a WinXP with base installation, to see how it runs.

I am a consultant and tend to work in a variety of environments. I carry a Thinkpad running VMWare Server over Ubuntu64 with 4GB of RAM. I've got a 320GB secondary hard drive that I use just for VM's and have 25 or so different virtual machines that I boot up as the circumstances demand.

They're a mix of Linux servers and workstations, Vista workstations and XP Workstations. I rarely use the VMWare server console. I access every one of them via one of the remote access methods.

For Linux, I usually install FreeNX or NXServer for desktop access and just SSH for commandline. On Windows, I always use Remote Desktop (RDP), but, on XP, that only works on the "Pro" versions, not the "Home" versions. If all else fails, I install VNC and use that. VNC is at the bottom of my list because it really is a last resort. The only thing it's better than is not actually being able to use the machine.

However, NX on Linux and RDP on Windows work WAY better than VNC. Other than little things like font smoothing and fancy desktop effects, the only big glitch would be if you are doing much with video or audio or DirectX-based stuff. Things like YouTube or other video do NOT like to work with any remote desktop protocol that I know of.

As far as performance, using Linux as a host for VMWare provides really good management of system resources. The Windows-based VM's aren't able to just gobble up memory, but still get it when they need to.

I do C# development all day in a virtual Vista workstation on Visual Studio 2008 and have absolutely no problems having 3-4 different solutions all open at once along with the normal stuff alongside over RDP on another machine, connected via wireless VPN.

I can flip over to the host OS and it won't even be touching swap space at all. As far as I'm concerned, it's a great way to work.

If you want to work with the same installation, you should seriously consider the Remote Desktop Server/Client solution, bundled into every windows OS from XP. Basically, this app displays the view from your remote desktop to your local one, using highly compressed images; this works even via low-bandwidth internet connections While the XP version can only handle one user simultaneously, the one in Windows Server 2003 (and in Windows Server 2008, I presume) can handle multiple users (up to a certain limit).

Disadvantages, and side-effects include:

• virtual pc via RDC is slow
• anything using the 3d acceleration will be slow (at least using XP/2003)

Personally, I would go down the route of using a virtual workstation with some remote logon software. The network performance of VMWare has always been good in my experience, and depending on the OS, there may be a decent remote logon provided.

I guess you can live with Logmein Free. [Or Pro if u want those features]

回答5:

Well, you don't say what OSs are involved, so.....

For windows, I find that Remote Desktop works as well or better than anything else, although if you pay for the RealVNC version with the mirror driver, that's supposed to be as good. For off site access for windows, www.logmein.com (the free version) works very well.

If Unixes are involved, then VNC is definitely the way to go, there are various solutions for doing this remotely. Everything from redirection servers, to just forwarding a port in your firewall to an ssh server and setting up the various tunnels.

Performance of VMWare is very good, and I can run a SQL Server slice, a web server slice and develop on my laptop simultaneously. The VM slices reside on a USB 2 portable drive and make it easy to port between my laptop and desktop.

VM Console works well for accessing each environment, and depending on the configuration you set up with NAT vs. Bridging you can UNC to shares on slice.

The nice by-product of this is that should you host machine take a nose dive you can quickly recover your development environment.
