For a number of years I have been presenting a virtualization seminar
for the annual virtualization deep dive day. I was able to demo a Linux
host with Windows XP, Windows 7 and Windows 8 as guests. The one thing
that surprised me was that on my netbook, Windows XP actually performed
reasonably well, although I would not recommend using a netbook for
virtualization. Also, at work I set up a number of Linux guests running
our product.
One of the main determinants would be graphics. The host OS is going to
be able to make good use of the graphics chip where the guest OS may be
somewhat limited although there are hardware solutions. But, for the
most part it does not matter. Windows has become more stable. In
addition, to virtualize Windows you would either need to PtoV the
installed Windows, but a new Windows license, or download an instance if
you are a MSDN subscriber.

Personally, I run Linux almost exclusively; I typically only need to boot
Windows a few times a year, so running Linux in a VM on a Windows host
makes no sense for my usage patterns.
When I do need to run Windows, its performance in a VM is abysmal, so I
stick with dual-booting for performance reasons.

What is your experience virtualing Linux on Windows, or Windows on Linux?
I want access to both systems so I tend to do one or the other. I do not
consider "dual booting" a solution since I want to run both systems not
either system.
Since most laptops come with windows it's less of a hassle and less risky
to just leave it be, and virtualize linux. I currently boot Windows and
virtualize Linux using VMWare Workstation.
I'd been doing the reverse for years and while I would prefer running
linux native, it was more sensible on a desktop where I could hand-pick the
components. It was also a time when boots were over ten times longer,
windows was much less stable, and required reboot more often.
I know I've been manipulated by the Microsoft UEFI/secure boot conspiracy
and licensing. Not sure it's legal for my windows license to reverse
virtualization. I have an ultimate license for windows 7 for the old
desktop that specifically allows virtualization. I am not sure windows 10
upgraded from windows 8 would "like" running in a virtual machine. They
have made it more convenient for me to just virtualize linux.
For now I plan to leave things as they are but I am researching UEFI and
how to disable it to at least know how I'd boot to a USB key as the
no-opt-out automated Windows 10 updates could break something. I have a
Lenovo laptop. Y50-70. To deal with firmware settings I have to go through
several menus in Windows control panels to trigger it to enter a settings
mode that is bios-like. A few people have said Lenovo is good for Linux.
Does that apply to my model?
*Advantages of Linux on windows*
Hardware works without fiddling more often.
Less work, so more time to do other things. I have no specific problem with
doing anything I could do running Linux natively. Since it's not broken, I
do not see a reason to fix it.
New hardware was a generation newer and an upgrade to using ssd instead of
HD so I do not notice a performance costs.
*Disadvantages of Linux on Windows / Reasons to **switch*
It is a bit more productive for me using Linux as my primary OS.
It does not "feel" as secure. It was nice to know I had virtual disk save
points to revert windows if i got a virus on my system.
Not as "cool" or "hip" as Linux native.
System could be more easily possessed by some Cabal.
