Anyone has experience with Xen

post #1 of 12
Thread Starter 
Xen, as I hope some of you know, is software that allows you to run multiple OS via Virtualization (I think?).

Anyway, I'm thinking of using this to have so I can run winXP directly from FC6 x64. What kind of performance loss am I looking at? I find it so annoying to reboot and switch between FC and Windows, so this Xen software seemed interesting, and free!

I know VMWare also make some sort of Virtualization software, but because FC6 has a built in Virutal Machine Manager (backend is Xen), it seems like the right choice.

Please excuse any vocabulary misuse, I'm still learning

That depends on what you're going to use it to. So, what are you going to use it to?

Use it to? I'm not sure I understand but I hope my answer will be the one you're looking for.

As I understand it Virtualization allows you to turn a single PC into 2 PCs, with distinct caracteristcs including Memory usage, HD usage, CPU usage (or allocation of cores in a multi-cpu environment), etc.

I find it a pain that I can't usen Windows programs while I'm in Fedora. So I would format my entire PC, partition my 160GB drive and allocate 25GB to Fedora.

Then I would run the Xen Wizard within fedora and Install windows xp.

Via a Virtual Machine Viewer, I'd be able to play around in windows programs within Fedora (so no more dual-boot).... so that of the 4 workspaces I have in Fedora, 3 would be for Fedora and the other workspace could be for XP, so I could easily switch between both. I'd allocate the bulk of the CPU power to Fedora (I fold on SMP client) but would leave XP with, say, 256 MB of RAM and a bit of CPU power too... mostly to watch movies, play WMA files... that sort of thing.

So, does anybody use Xen in this manner? Or am I completely wrong about the correct usage of Xen?

Regards,

jimmy

If I am right, I'll buy a Q6400 when the come out with some more RAM, say 2GB instead of the 1 I currently have.

IMO Xen is hopelessly difficult. I'd use VMWare.

Ok, they have a "VMware server" which is free. However, it doesn't mention that the host could be based on x64 architecture.... I'm downloading now (99MB)... won't play with it until tomorrow though.

I don't want to run it within windows, as this would probably slow down my folding. The host has to be Fedora..

Yeah VMware should work fine for every-day XP applications.

Why don't you just use WINE?

Wine, like most other software for Linux, it free, and is a Windows emulator that runs on linux, not just a virtual PC.

Check out www.winehq.org

Wine is an Open Source implementation of the Windows API on top of X and Unix.

Think of Wine as a compatibility layer for running Windows programs. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code, however Wine can optionally use native Windows DLLs if they are available.

Like others have stated, I'd go with WINE, but to answer the question on "performance loss", you'd be looking at the OS running at around 80% its normal speed.
