Hi Stefan, Thanks for getting back to me regarding your QEMU on Windows.
I actually do realize that QEMU on a Windows os is much slower, but I have limited options in this area as the basis of the project (which will take a fair amount of time and effort to get going) is to have a Type 2 Hypervisor something like QEMU or Virtualbox which is able to co-exist, and run concurrently, with commodity Windows Desktop systems. I also have been considering CoLinux, AndLinux, and SpeedLinux for a possible starting point as well. For pure linux based machines, as Type 1 Hypervisor like Xen might do the job, but currently I want to go with a development that will allow the VM to run concurrently with Windows. The project goal is to develop a distributed shared memory shared resource SSI system such that one massive virtual computer can span a great many desktops and dedicated systems. It's a very ambitious and long-term project and I am just trying to determine the best existing VM from which to start the effort for which it looked as though QEMU, although slower on Windows machines, has the best cross platform as well as a code-base that is not overly heavy like Virtualbox. Thanks for the links and I will start looking into the information. If you have any suggestions on a possible approach towards these goals then I would be happy to hear them as well. Cheers and have a great day, Lonnie -----Original Message----- From: Stefan Weil [mailto:s...@weilnetz.de] Sent: Wednesday, December 04, 2013 12:39 PM To: Cumberland, Lonnie Cc: qemu-devel@nongnu.org Subject: Re: [Qemu-devel] QEMU For Windows Am 04.12.2013 16:30, schrieb Cumberland, Lonnie: > > Greetings All, > > I hope that you are well today. > > For a learning/development project, I am interested in the "QEMU for > Windows" which is being developed by Stefan Weil as I think that it > would make a great starting point.

Cumberland > Hi Lonnie, please start with reading the available documentation, especially these pages: http://wiki.qemu.org/Documentation/GettingStartedDevelopers http://wiki.qemu.org/Hosts/W32 I strongly suggest using Linux instead of Windows if your project is based on x86 hardware, because QEMU on Windows is much slower than QEMU on Linux with KVM hardware virtualization. Even for building Windows binaries, Linux is the better build platform. The QEMU binaries for Windows on qemu.weilnetz.de are built with MinGW-w64 on a server running Debian/GNU Linux (wheezy), the code is from my personal QEMU repository git://repo.or.cz/qemu/ar7.git.
