| # Summary | |
| A few notes I took to see if I could use MacOS as Hypevirsor in a similar fashion to Linux | |
| I wanted to see how few addons were needed instead of using Parallels, Virtual Box, VM Fsion etc. | |
| The idea is to use QEMU, Hypervisor Framework (https://developer.apple.com/documentation/hypervisor) and some custom host networking. | |
| # Installations | |
| brew install qemu (For controlling Hypervisor Framework) | |
| brew install cdrtools (For making cloud init iso's) | |
| http://tuntaposx.sourceforge.net/download.xhtml (For customer tap based networking) |

Light font smoothing defaults command (my selection):
defaults -currentHost write -globalDomain AppleFontSmoothing -int 1
This brief tutorial will walk through the process of creating a systemd template unit file for starting Envoy sidecars for use with Consul service mesh.
Template unit files allow systemd to address multiple units from a single configuration file. You can call a systemd template unit file using a special format to use this feature:
| #!/usr/bin/env bash | |
| set -euo pipefail | |
| help() { | |
| cat <<EOF | |
| vmctl [COMMAND] [ARGS] | |
| Launch firecracker VMs from configuration templates with networks | |
| managed by CNI. VM configuration is stored in $VM_CONFIG_DIR | |
| and network configuration is stored in $NET_CONFIG_DIR |
