Once you have a successfully running openQRM Server you can follow the steps below for a Proxmox VE Solution.

These instructions will enable you to proof of concept the Proxmox VE Solution as a tmpfs deployment, however the clustering requires special initialisation. We have developed the ATU Plugin to orchestrate these steps for synchronized cluster initilisation on start and backup configuration on shutdown.

  1. Download PVE Kernel - http://download.proxmox.com/debian/dists/buster/pve-no-subscription/binary-amd64/pve-kernel-5.4.114-1-pve_5.4.114-1_amd64.deb
  2. Install Kernel
  3. Add Kernel to openQRM
    1. (Replace KERNEL_NAME, KERNEL_VER, OPENQRM_UI_USER, OPENQRM_UI_PASS, SERVER_NAME with the appropriate variables) openqrm kernel add -n KERNEL_NAME -v KERNEL_VER -u OPENQRM_UI_USER -p OPENQRM_UI_PASS -l / -i initramfs
    2. openqrm kernel add -n pve-5.4.114-1 -v 5.4.114-1-pve -u OPENQRM_USER -p OPENQRM_PASS -l / -i initramfs
      1. If you are using a self signed cert you may need to load the https call back manually; https://SERVER_NAME/openqrm/base/server/kernel/kernel-action.php?kernel_command=new_kernel&kernel_name=KERNEL_NAME&kernel_version=KERNEL_VER
  4. Create Image - To create an image for Proxmox which can be used as a tmpfs image, follow these steps;
    1. apt-get install debootstrap
    2. Create directory mkdir -p /exports/proxmox_image/dev/pts
    3. debootstrap --arch amd64 buster /exports/proxmox_image/ https://deb.debian.org/debian/
    4. mount --bind /dev/pts /exports/proxmox_image/dev/pts
    5. mount --bind /dev/ /exports/proxmox_image/dev/
    6. mount --bind /proc /exports/proxmox_image/proc
    7. mount --bind /exports/proxmox_image/ /exports/proxmox_image/
    8. mount --make-rprivate /exports/proxmox_image/
    9. mount --bind /var/run/dbus /exports/proxmox_image/var/run/dbus
    10. chroot /exports/proxmox_image
    11. apt-get install wget net-tools screen locales collectd
    12. dpkg-reconfigure locales
    13. Follow steps (Start at "Install Proxmox VE") @ https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Buster
      1. We do not need to install grub
    14. set root password; passwd
    15. implement noclear for getty/inittab;
      1. mkdir -p /etc/systemd/system/getty@tty1.service.d/
      2. edit file; /etc/systemd/system/getty@tty1.service.d/noclear.conf add contents;

        [Service] TTYVTDisallocate=no

    16. If using the ATU Plugin then disable services: pvedaemon, pve-proxy, pve-manager, pve-cluster, cman, corosync, ceph, pvestatd, qemu-server, rrdcached, spiceproxy,
  5. Activate NFS Storage (if not already done so)
    1. Under Plugins -> Storage -> NFS-Storage
    2. Add NFS Storage;
    3. name "openqrm-nfs"
    4. Deployment Type: "nfs-deployment"
  6. Add NFS Volume (this triggers tmpfs storage)
    1. Under Plugins -> Storage -> NFS-Storage -> Volume Admin -> Edit -> proxmox_image "ADD IMAGE"
  7. restart server/vm incase of duplicate services started from chroot image initialisation
  8. Now create a TmpFs-Storage: Plugins -> Storage -> Tmpfs-storage -> Volume Admin -> New Storage
    1. Name: openqrm-tmpfs
    2. Deployment Type: tmpfs-storage
  9. Now Create an Image: Components -> Image -> Add new Image -> Tmpfs-root deployment -> click edit on the "openqrm-tmpfs" -> Click "ADD NEW VOLUME"
    1. Name: pve5
    2. Size: 3 GB
    3. Description: proxmox ve 5
  10. Now you will need to link a resource to a server. A resource is a blank system/server/chassis and a Server is a configuration applied to a resource/blank system. So you can either manually add a server or if a system has booted via dhcp/pxe then that system will be selectable and named "idle" for this next step.
    1. Click "ADD A NEW SERVER"
    2. Select the resource or manually setup a server
    3. then select n image for server, select the pve5 = tmpfs-deployment as previously setup (leave the tick on edit image details after selection.
    4. then select "Install from NAS/NFS" select the "proxmox_image" as above then click submit
    5. then select the kernel 5.4.114-1-pve then click submit
    6. Done
  11. Tar Image
    1. mkdir -p /usr/share/openqrm/web/boot-service/tmpfs/
    2. cd /exports/proxmox_image
    3. tar --exclude=usr/src --exclude=var/lib/apt/lists --exclude=usr/lib/jvm --exclude=var/lib/apt/lists --exclude=usr/share/man --exclude=usr/share/doc --exclude=usr/share/icons --numeric-owner -czf /usr/share/openqrm/web/boot-service/tmpfs/proxmox_image.tgz .
  12. Create NFS Image link to TmpFS image


implement noclear for getty/inittab

set root password (otherwise not able to login)


The ATU Plugin is optimised for Proxmox Cluster Deployments and TMPFS Server Configuration Sync Initialise ATU plugin

Create custom FS
