Is there any free virtual machine software (like VMWare) that can be used for testing Fedora installation?
I want to test the latest version of my delta rpm system for keeping Fedora boxes updated over low bandwidth links. But I don't have a spare machine...
Thanks, Joe.

Xen: Which is in FC4 and will be in FC5
VMware GSX server: Now free, but the new free version is still in beta last I heard.

No, VMware Server is gratis. VMware GSX is a separate product.

VMware Server is VMware GSX (next generation, so essentially just a new version of the same product - GSX is being discontinued for all i know).

Among the suggestions provided for VMs in Fedora: qemu, xen, vmware and linux-vserver, is there any clear preference in terms of ease of use and integration into the distro? Since xen is the only one that is actually part of Fedora I'd like to assume that there's some quantitative advantage to it over the alternatives. Is this not the case?
I guess my question could be rephrased: If xen comes with Fedora is there a reason for someone who wants to run virtual test systems in Fedora to use anything else?

Xen is a para-virtualisation system - the virtualised system/os needs to built in a way that is appropriate for virtualising. This means that you are (currently) unable to use xen for running windows images or even installing older (non xen aware) versions of Linux. Since Xen requires support at kernel level it really needs to be in core if its supported (and it is both in core and supported).
Qemu is a more complete or maybe more traditional virtualisation setup - it effectively emulates the hardware of a standard system. However its rather slower than Xen. You can also emulate an entirely different architecture under qemu (I have installed a x86_64 fedora on a i386 under qemu - but it was glacially slow). There is a non-free kernel module that speeds up emulation of i386 on i386. Qemu can also be used to run binaries for one system on another without emulating the complete system - in a way vaguely analogous to what wine does.
VMware is effectively a commercial, shinier, faster version of qemu (VMware would dispute this - they were there way before qemu). Its much easier to manage and probably better on some cases where the qemu emulated hardware is insufficient. Its obviously not a candidate for Fedora even in its new free (gratis) form. There is also a big brother - ESX - which runs virtual machines over an ESX kernel running on bare metal, which is used for virtualising services. I don't think VMware does anything other than i386 running on i386 (unlike qemu).
Qemu would be a good extras candidate. I'm a bit surprised to see its not in extras at present.

It can also do x86_64 running on x86_64, even if you're running a 32-bit OS. It can also do limited SMP.

It doesn't build against gcc4.

Well technically it builds, but you get somewhat erratic runtime results :-)

yup builds fine since ages with gcc 4 if you disable sparc and the compiler check.

because its to slow without kqemu(non free) and qvm86(gpl) does not run on x86_64 (last time I tryed)
Once upon a time, Nigel Metheringham nigel.metheringham@dev.intechnology.co.uk said:

Not entirely true: with new versions of Xen combined with certain CPUs (Intels today, AMDs some time this year), you can have full virtualization. People are running Windows along side Linux.
There's a higher overhead in running that way, so it is preferred to run with a Xen-aware OS.
Also note: I haven't tried this myself yet.

Linux-VServer (http://linux-vserver.org/) should have good Fedora Core support (host and guest).
