This KB explains how to automatically start virtual machines on Syneto Hyperion in a specific order.

Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

Step 2. Become Super User

sudo su

Step 3. Disable autostart for all VMs ("How to enable/disable VMs autostart in Hyperion")

Step 4. Create /usr/local/bin/start-hyperion-vms.sh file

vi /usr/local/bin/start-hyperion-vms.sh

IMPORTANT
Make sure to copy and paste the exact lines below (replace <vm-name1>, <vm-name2> and <vm-name3> with the correct information)

#!/bin/bash

logger "Ordered VM startup: begin"

# Ordered startup
virsh start <vm-name1>
logger "Started <vm-name1>"
sleep 20

virsh start <vm-name2>
logger "Started <vm-name2>"
sleep 30

virsh start <vm-name3>
logger "Started <vm-name3>"
sleep 40

logger "Ordered VM startup: completed"

Save and EXIT

:wq

To add more virtual machines to the startup sequence, copy the following three lines, modifying the VM name e increasing the sleep duration by 10 seconds.

virsh start <vm-name>
logger "Started <vm-name>"
sleep 50
These 3 lines should be placed between before the line logger "Ordered VM startup: completed".

Step 5. Make the script executable

chmod +x /usr/local/bin/start-hyperion-vms.sh

Step 6. Create /etc/systemd/system/hyperion-vms-autostart.service file

vi /etc/systemd/system/hyperion-vms-autostart.service

IMPORTANT
Make sure to copy and paste the exact lines below

[Unit]
Description=Ordered KVM virtual machine startup
After=network.target libvirtd.service
Requires=libvirtd.service

[Service]
Type=oneshot
ExecStart=/usr/local/bin/start-hyperion-vms.sh
RemainAfterExit=true

[Install]
WantedBy=multi-user.target

Save and EXIT

:wq

Step 7. Reload systemd

systemctl daemon-reexec

systemctl daemon-reload

systemctl enable hyperion-vms-autostart.service

systemctl start hyperion-vms-autostart.service
