From 79ef5b32fe6c493daeea24f4c5bee71ad61a91f6 Mon Sep 17 00:00:00 2001 From: Jonathan Nobels Date: Fri, 2 Aug 2024 12:00:41 -0400 Subject: [PATCH] natlab: fix unixgram plumbing and add mac virtualization Tweaked the unixgram plumbing to use the vm's remote unix address for write operations. Rudimentary macOS virtualization added which will spin up a VM with some hardcoded config options that work with natlabd's default settings in -dgram mode.
