<p class="MsoNormal"><span lang="EN-US">Hi everyone,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I am working on Insula (https://github.com/insula-rs), more specifically on the Windows loader.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The Insula project was started as lightweight VM / container environment for KVM/Hyper-V written in Rust.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Some of the goals are:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">* An abstraction layer to provide a platform independent interface for Linux/Windows / KVM/Hyper-V<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">* Support for Linux and Windows guest loaders<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">* Interface for hooks/callbacks:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> * security related host-side hooks for e.g. the detection of ring 0 exploits & security bypasses from the host.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> * optional generalized guest<->host communication interface, e.g. for a kernel-debugger transport layer or security software notifications<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> * optional host-side debug hooks to provide the ability to debug the VM at a low level<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Considering that firecracker already provide a lot of functionality, we have been looking into consolidating the code base, potentially joining a collaboration with the existing projects.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Since one of our goals is host platform independence, we would need Windows / WHV specific implementations / wrappers. Looking at the firecracker code, I found that kvm specific code is used here and there, but it doesn't
seem too bad and could probably be modified to separate the kvm specific code from generic code.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This is a first RFC to see what you guys think about these things, whether you would be interested in the mentioned pieces and any feedback you might have on that topic.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
