I think it's better to do it for all VMs that are in 'Up' state?

 And here I suggest adding a check (after some time?) that all VMs are
actually down, and if not, exit with an error?

If I remember correctly, if you use option "insecure=True", you can omit 
ca_file option:


connection = sdk.Connection(
  url=ovaddress,
  username=username,
  password=password,
  insecure=True
)

Hey,  thanks for sending this to me.  Works like a charm.  I have this tied
in with a UPS script that monitors the UPS on another system, and fires off
your script before a shutdown command.  Works pretty well so far!

I am using the default certificates.   Took me a second to find out where
they are stored, but after pointing directly to it, everything is working
like a champ.

Thanks!

I'm using something like this with ovirt-shell

vm_shutdown:

new_vm_shutdown_script now lists entries like this:

You can use python SDK.

Somthing like this should work

#!/usr/bin/env python

import ovirtsdk4 as sdk

ovaddress = ""
username="admin@internal"
password="*"

connection = sdk.Connection(
  url=ovaddress,
  username=username,
  password=password,
  ca_file='ca.crt',
  insecure=True
)

system_service = connection.system_service()
vms_service = system_service.vms_service()
vms = vms_service.list()

for vm in vms:
vm_service = vms_service.vm_service(vm.id)
vm_service.shutdown()

connection.close()

Marcelo,

I would greatly appreciate seeing a script!  It would be an excellent
chance for me to learn a bit about using ovirt from the command line as
well!

Or with Ansible.
But in 4.2, I believe the VMs are registered with libvirt and will be shut
down nicely with the host.

Do you can do this with python sdk, do you can build a list and shutdown
all vms. If you want I can make a script to you tomorrow.

[ovirt-users] Shutdown all VM's command line

[Wesley Stewart]

Is there an easy way to do this?

I have a UPS connected to my freenas box, and using NUT and UPSC I can
monitor the battery level on my centos 7 host.

In the case of an emergency, and my UPS goes below, lets say 40% battery, I
would like to make a script to shutdown all running VMs, and then reboot
the host.

Otherwise I am afraid of sending a straight reboot command to the host
without taking care of the virtual machines first.

Thanks!
