[-- Attachment #1 --] Does Bhyve support a form of shared memory between VMs for low-latency inter-vm communication? I am interested in implementing something similar to Xen's vchan, it relies on Xen's grant reference table mechanism and event channels associated with the shared memory region (ring buffer) The purpose for doing so is to create secure communication between VM's ala Qube's qrexec protocol. https://www.cs.uic.edu/~xzhang/vchan/ https://mirage.io/blog/introducing-vchan https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=xen/include/public/io/libxenvchan.h;hb=HEAD https://www.qubes-os.org/doc/qrexec-internals/ [-- Attachment #2 --] <div dir="ltr"><div>Does Bhyve support a form of shared memory between VMs for low-latency inter-vm communication?</div><div><br></div><div>I am interested in implementing something similar to Xen's vchan, it relies on Xen's grant reference table mechanism and event channels associated with the shared memory region (ring buffer)</div><div><br></div><div>The purpose for doing so is to create secure communication between VM's ala Qube's qrexec protocol.</div><div><br></div><div><a href="https://www.cs.uic.edu/~xzhang/vchan/">https://www.cs.uic.edu/~xzhang/vchan/</a></div><div><a href="https://mirage.io/blog/introducing-vchan">https://mirage.io/blog/introducing-vchan</a></div><div><a href="https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=xen/include/public/io/libxenvchan.h;hb=HEAD">https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=xen/include/public/io/libxenvchan.h;hb=HEAD</a></div><div><a href="https://www.qubes-os.org/doc/qrexec-internals/">https://www.qubes-os.org/doc/qrexec-internals/</a></div><div><br></div><div><br></div></div>;
