OpenVMM – A New VMM for Windows and Linux, Written in Rust

Note this “disclaimer” in the guide:<p>&gt; In recent years, development efforts in the OpenVMM project have primarily focused on OpenHCL (AKA: OpenVMM as a paravisor).<p>&gt; As a result, not a lot of &quot;polish&quot; has gone into making the experience of running OpenVMM in traditional host contexts particularly &quot;pleasant&quot;.<p>&gt; This lack of polish manifests in several ways, including but not limited to: […]<p>&gt; • <i>No API or feature-set stability guarantees whatsoever.</i><p><a href="https:&#x2F;&#x2F;github.com&#x2F;microsoft&#x2F;openvmm&#x2F;blob&#x2F;main&#x2F;Guide&#x2F;src&#x2F;user_guide&#x2F;openvmm.md#disclaimer">https:&#x2F;&#x2F;github.com&#x2F;microsoft&#x2F;openvmm&#x2F;blob&#x2F;main&#x2F;Guide&#x2F;src&#x2F;use...</a>

In case anybody else wondered VMM = Virtual Machine Monitor.

Thank God this VMM is written in Rust, otherwise I would be very skeptical. I don&#x27;t care about features or purpose or technical advantages, give me Rust or give me death.

Cargo.lock has 8750 lines. Is that normal for something like this?<p>For comparison, QEMU basically just needs glibc, glib and zlib for basic functionality.

How does this relate&#x2F;compare to CloudHypervisor, another Rust based VMM that has been around for couple of years<p><a href="https:&#x2F;&#x2F;github.com&#x2F;cloud-hypervisor&#x2F;cloud-hypervisor">https:&#x2F;&#x2F;github.com&#x2F;cloud-hypervisor&#x2F;cloud-hypervisor</a>

Slides from Linux Plumbers talk about OpenHCL: <a href="https:&#x2F;&#x2F;lpc.events&#x2F;event&#x2F;18&#x2F;contributions&#x2F;1956&#x2F;attachments&#x2F;1642&#x2F;3391&#x2F;linux%20plumbers%20bof.pdf" rel="nofollow">https:&#x2F;&#x2F;lpc.events&#x2F;event&#x2F;18&#x2F;contributions&#x2F;1956&#x2F;attachments&#x2F;1...</a>

Half the user guide is empty.<p>I want to understand what communication channel(s) it has from guest to host. It&#x27;s not clear from the cut-and-paste support described in the VNC section of the manual, how this works and what other functionality might be supported.

Rust was something i thought was a cute little language years ago, much like i thought python was. I didn&#x27;t pay attention for like 2 years and it feels likes it&#x27;s everywhere and everything.<p>Time to learn.

it&#x27;s written in rust is the <i>only</i> thing worth mentioning about it? congratulations on writing a thing that does something, i guess

A very interesting project. If I understand correctly it’s being used for Azure infrastructure.

A New Virtual Machine Monitor for Windows and Linux that happens to be written in Rust

VMM == Virtual Machine Monitor, &quot;such as Hyper-V, QEMU, VirtualBox&quot;.

Nice! Would be pretty cool if this supported bhyve on FreeBSD.
