InformationWeek has a good story on what OS's users install in their virtual machines.
Windows Predominates On Virtual Machines
Sage Research said 96% of the respondents use Windows on their virtual servers and 52% are running Linux.
Many sites use more than one brand of operating system to run virtual machines. The runner-up was Linux, with 52% of the respondents using the open source operating system. Unix was third at 30% and Solaris fourth at 29%. The figures do not add up to 100% because sites in some cases are using multiple brands of operating system in their virtual machines. The Mac OS was used by 12% of respondents and NetWare by 6%.
Does this match your guest VM inventory? Interestingly, Mac OS is not clearly defined (OpenStep? darwin? OS X? OS X Server?) is run twice as often as Netware even though virtualization vendors do not officially any variants, yet.
I have five permanent Windows VMs in my inventory (Windows 2000 - Windows Server 2008 w/Hyper-V). I also have about 20+ machines of various Linux distros and versions, bsd variants (open, free, net, darwin) but no OS X VMs (working on getting a copy of Leopard Server) and no Netware (gag!)
Here's my list of what I have available and installed under Fusion:
Windows Vista x64
Windows 98
Ubuntu 7.10 x64
Solaris 10 x64
OS/2 WARP v4
BeOS R5
FreeDOS 1.1.27
Admittedly, I don't do much with a lot of these VMs -- some of them are just part of my own personal OS museum (and a bit of nostalgia, and just because I can do it). I have a Windows 3.0 with MMX CD kicking around somewhere, so that might be one of my next projects (if I can find a suitable era version of DOS to go with it).
Yaz.
In approximate usage order (highest to lowest), my portfolio looks like:
Solaris Nevada
Windows XP
OpenSolaris (Indiana)
Ubuntu Gutsy
Outside of VMware, I run Commodore Amiga and Sinclair Spectrum emulators a lot too ![]()
In no particular order, I run:
Windows XP
Windows 2003 Server (32-bit)
Ubuntu Gutsy (32-bit)
Solaris 10 U4 x64
RHEL 4 x86
SLES 10-based "soft-appliance"
Most of my stuff is work related - we use a lot of VMware Workstation for customer demo and self-education purposes. Fusion has worked out great for transportability to/from the VMware Server and Workstation environments I use at work.
