Accessing the RAM of a QEMU Emulated System from Another Process

The title sounds like its a vulnerability that allows a random process access to qemu memory but it is not.<p>Its a 2021 tutorial that describes how to configure qemu to share memory between a host process and a qemu machine through &#x2F;dev&#x2F;shm.

There is rather large ecosystem of tooling for poking and peeking the insides of VMs, usually called &quot;VMI&quot; (virtual machine introspection). kvm-vmi is one such example, but there are many others <a href="https:&#x2F;&#x2F;github.com&#x2F;KVM-VMI&#x2F;kvm-vmi">https:&#x2F;&#x2F;github.com&#x2F;KVM-VMI&#x2F;kvm-vmi</a>

There&#x27;s a library [1] that implements message passing and locking for communiction between VMs in a similar way and is used by the awesome looking glass project to send the accelerated GPU video stream from a vm to the host or a different vm.<p>[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;gnif&#x2F;LGMP">https:&#x2F;&#x2F;github.com&#x2F;gnif&#x2F;LGMP</a>
