I am wondering if anyone has successfully ran any virtual windows7(or vista) OS's on their linux ec2 instance. We're getting a high memory large instance and I have one user who wants to run a .net app that needs some heavy cpu at times but other wise will won't be active(its basically the boss's trading optimizer).
I'm sort of in the a bind because all of our system apps run in linux. So I wanted to create a windows7 VM within the linux OS. I got this to work with qemu but the performance was pretty bad because apparently qemu only supports one cpu per os.
I'm wondering if people could share experiences installing these types of software(virtualbox, qemu, vmware, etc.) in the cloud? My requirements is it should be able to use multiple cpus(so we need okay performance..doesn't have to be mind blowing fast but not 10 minutes to open internet explorer like it currently is with only one cpu) and should run within linux. We're willing to purchase a tool if one works so it doesn't have to be open source.
Thanks for sharing your experiences
