A set of utilities to help you manage VMs with Virtualization.framework
Installation
# make sure xcode command-line tools are installed
xcode-select –install
# run build, install. This will install vmcli and vmctl to /usr/local/bin
make
sudo make install
You have now finished installing vmcli and vmctl
Set envirionment variable VMCTLDIR to ~/VMs so vmctl knows how to find VMs.
If you don’t set this, vmctl will use current working directory to find VMs.
echo’export VMCTLDIR=”$HOME/VMs”‘>>~/.zprofile
export VMCTLDIR=”$HOME/VMs”
Provision a Ubuntu VM, and install that to ~/VMs.
The VM will auto create your user with your ssh public key at ~/.ssh/id_rsa.pub.
make build/vm/ubuntu
mv build/vm/ubuntu ~/VMs/ubuntu
Optionally expand the VM volume, for example to 16G.
dd if=/dev/null of=~/VMs/ubuntu/disk.img bs=1g count=0 seek=16
Optionally edit the VM config for more RAM and/or CPU cores
Start the VM
Attach to the serial console, use (CTRL+A – D to quit)
vmctl attach ubuntu
You can use vmctl ip ubuntu to check your VM IP.
Wait for the VM to boot and ssh into the VM
vmctl ssh ubuntu
You should shutdown the VM using ssh within the VM.
If that’s not an option, you can forcibly shut it down.
vmctl stop ubuntu
