I am trying to create an application that runs on windows. I want this application to download a "disk image" from the network (from pre-assigned server) and create a virtual machine based on it. This VM would run for a specified number of hours and then shutdown.
I want to use VirtualBox by scripting it. I found VBoxManage command and it seems to be what I am looking for. However, it seems that VirtualBox tools store their configuration as XML files in User home directory. I did learn that i can change the value of VBOX_USER_HOME environment variable to control where they are stored. However, I am not sure whether this is enough.
My problem is that the user may already have installed VirtualBox on his/her computer. I do not want my application code (and it's packaged VirtualBox binaries and conf) to mess with the existing installation.
How do I cleanly isolate my application specific VirtualBox binaries and configuration from the potentially pre-existing installed VirtualBox setup? (Even if both instances of VirtualBox binaries are being used at the same time)
I chose VirtualBox because of it's open source license and applicability of commercial use (if I compile my own binaries from the source) and because it works on Windows too (heard QEMU support for windows is still not stable). Will VirtualBox suffice for my use-case or should I look elsewhere?
Thanks for reading so far :)
