Use Parallels Box

For example: bytesguy/ubuntu-server-20.04-arm64

Steps:

1. Add box

   vagrant box add bytesguy/ubuntu-server-20.04-arm64
   
   # choose 'parallels' and wait
   

2. Locate the box

   # find the box dir
   find .vagrant.d/boxes -name '*bytesguy*'
   
   # enter the main dir of this box
   cd ~/.vagrant.d/boxes/bytesguy-VAGRANTSLASH-ubuntu-server-20.04-arm64/1.0.0/parallels/
   

3. Find the disk file: *.hds

   # run this command with in the 'parallels' dir
   find . -name '*.hds'
   
   # example result: ./Ubuntu Server 20.04.pvm/harddisk1.hdd/harddisk1.hdd.0.{5fbaabe3-6958-40ff-92a7-860e329aab41}.hds
   

4. Convert it to qcow2 image

   qemu-img convert -c -f parallels -O qcow2 ./Ubuntu\ Server\ 20.04.pvm/harddisk1.hdd/harddisk1.hdd.0.\{5fbaabe3-6958-40ff-92a7-860e329aab41\}.hds box.qcow2
   

5. Run local qcow2 with vagrant-qemu (see example in readme)

Notes:

• the generated box.qcow2 can be used again for different machines
• it's the user's response to maintain the generated box.qcow2
• the example box may hang after vagrant up, see Fix ubuntu hang for details
