Scripts to start VM when another host/VM finishes booting 2024-03-19

Stux submitted a new resource:

Scripts to start VM when another host/VM finishes booting - So you virtualized your router and now you need to orchestrate your VMs?

I had a need to start a VM only after another one had finished booting.

This script "start_vm_after_host.sh" will allow you to enter a host's IP address, and SSH port.

The script will then start the the specified VM when the sshd server on the other specified host begins returning SSH response.


I have a pfSense VM which is my network router using PCIe Pass-Through. As its the DHCP server and DNS resolver I do not want my VMs to launch automatically until after this VM finishes launching...

Hello,

Probably you can also use a different command pipe to find a VM ID given VM Name.
Something like:

Code:

root@tn-xeond[~]# midclt call vm.query | jq --arg vmname "icinga" '.[] | select(.name == $vmname) | .id'
1
