VMWare Fusion.
Haven't tried Virtualbox yet. That's my next step

qemu, since it's easy to figure out by the documentation and fairly portable.
On a side note, I hate using virtualization software period.

In the beginning I also hated virtualisation...
but now I pretty much love it I use Xen on CentOS and have FreeBSD as a guest OS. On my Mac I use VMware fusion (which is actually a great product) and for my job I run VMware ESX. Why is xen not in the list? And KVM? Or is it only virtualisation that works on *BSD? Greetings all! |

I really am enjoying my using VirtualBox. While it is the lesser known product it has two things going for it in my workplace. 1) The ability to run Solaris as a host. 2) The open source version will compile and run with a FreeBSD host. I notice you did not list Virtual PC.
Question: Am I missing something about Xen or did virtualbox end up incorporating xen once Sun owned them all? |

Hey ! Can't vote!
Which one do you use : all. Which one do you prefer : none. There are blondes, brunettes, redhairs, which one do I prefer? Just get the bl**dy f***ing job done. Am an equal opportunity user. As such, my vote cannot be casted.

Emulation/Virtualization is lame, but if I had to do it.. QEMU, none of those other options are available for BSD.

You really need to specify which type of virtualisation software you want to discuss. I was all set to vote and post some long comments ... but then realised you were only discussing host-based VM software (VMWare Server/Player/Workstation, QEmu, VirtualPC, etc). That's so blase.
Now, if you want to talk about hypervisors (Xen, Linux-KVM, VMWare ESX) and other lower-level VM software (and hardware), I'll be all over that. |

Virtualbox on Linux or Mac OS X boxes, Qemu on FreeBSD.
>VirtualBox is based on QEmu, and has no relation of any kind to Xen. To some degree only, but they were responsible for some code in VirtualPC too.

VirtualBox only uses Qemu code for certain things. Otherwise, much of the code is still different from whatever else is available.
Here's what I'm really wondering about, at least ever since I read that VMWare's model is to run as many instructions natively as possible. What's the role of CPU VT instructions, then? I thought that CPU VT instructions made this possible, but VMWare has been doing this before the instructions were ever available. By the way, KVM was listed. I said "Qemu (various combos or not)". Xen is in a class all on its own, which is why it's not appropriate here. I don't think Virtual PC is available for Unix...

Latest versions of VMWare ESX/GSX, I believe, can make use of the virtualisation features in CPUs. But I have very little info on that subject. Quote:

Ok, that's my mistake then. VMWare Workstation and Player only.

The polling question that was asked was which one do you prefer... I prefer VMware, but we use parallels for cost-efficiency. And parallels isn't bad... it's just not my first choice.
At home, it's actually virtual-PC2007 on windows boxes... free and easy on a typically not-so-free-and-easy platform. Funny how that works.

According to their VMI Performance PDF, they continue to use binary translation, as their current implementation is faster than their experimental hardware virtualisation implementation. This is for VMWare Server ESX 2.0. There is mention of a hardware assisted version of the VMM in this paper from 2006 that mentions experimental support for hardware virtualisation in VMWare Server 1.0.1. However, there is no mention anywhere (that I can find) on their website that says this is actually available and usable. So, if they support hardware virtualisation, they go to great lengths to hide that information from the public. |

Well, I couldn't find much information either, at least on official page presenting VMware Workstation. So I Googled a bit and found the reference link mentioning it. After Googling more I found these:

So you're right, they're not so vocal in saying that "the product" suports it, don't know why either. |

I would also add Xen/xVM and KVM to the list.
