virtualmachine allows to run your assembly code on a VMM instantly, using Ruby.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install virtualmachine
Here's a sample code. This will create a VM named 'vm0' with 128MB memory, executes an assembly code witch passed to load_asm().
require 'virtualmachine' vm0 = .('vm0', 128) vm0.load_asm(<<EOS) mov dx, 3F8h mov al, 2Ah loop: out dx, al jmp loop EOS vm0.run
- Currently, virtualmachine only supports FreeBSD-10 or later, because it built on BHyVe. Need to support Linux KVM.
- Page table, GDT, control registers are pre-initialized, hardcoded. Need to find better way to do it.
- No way to read/write guest registers and guest memory area. Need more APIs.
- Due to it's hardcoded, you can't choice 16bit/32bit mode. It always runs in 64bit mode.
- Because BHyVe doesn't have a BIOS, you have no way to call it.
- Fork it
- Create your feature branch (
git checkout -b my-new-feature)
- Commit your changes (
git commit -am 'Add some feature')
- Push to the branch (
git push origin my-new-feature)
- Create new Pull Request
