I created a special Debian 10 preseed iso just for my Proxmox kvm machines. I can go from zero to ready to rock in under 10 minutes!

The preseeded iso starts automatically, installs a few key packages, sets vim as my default editor and copies my ssh public key to my authorized_keys file so I can run the Ansible playbook right after install.

• I created the preseed file then added it to the ISO using my Zero Interaction method.
• https://gitlab.com/preseed/preseed-kvm/-/blob/da3402a1f9331fd23816703f62057091b7a36045/preseed.cfg

I created a small playbook to configure the system for me so it's set up the way I like.

• Run it like so:

  ansible-playbook -v -b --ask-become-pass -i xxx.xxx.xxx.xxx, ansible.yml

• https://gitlab.com/ansible9/ansible-kvm/-/blob/master/basic_kvm.yml

• Open the Proxmox web interface
• Upload the newly created preseed-iso to your Proxmox storage
• Create a VM with whatever settings you want, using the preseed-iso for the CD/DVD disk image.
• Start the virtual machine.
• Wait for it to complete. It took roughly 7 minutes for mine.
• Run the ansible playbook.
• Enjoy!

• ssh into Proxmox:

  ssh user@proxmox

• The iso's on my system are located at /media/sas/data/template/iso. Use your favorite file transfer method to get the iso file there (or the iso storage location on your system).
• List current VMs:

  sudo qm list

• Pick a free vmid and create a new VM with your preferred settings:

  sudo qm create 150 --cdrom sas-storage:iso/preseed-debian-10.4.iso \
  --name preseed --numa 0 --ostype l26 \
  --cpu cputype=host --cores 2 --sockets 2 \
  --memory 4096  \
  --net0 bridge=vmbr90,virtio \
  --bootdisk scsi0 --scsihw virtio-scsi-pci --scsi0 file=ssd-lvm:32 \
  --serial0 socket --vga qxl --audio0 device=ich9-intel-hda,driver=spice

• Start the vm:

  sudo qm start <vmid>

• Wait for it to complete.
• Run the ansible playbook.
• Enjoy!
