Shutting down "Protect from accidental shutdown" VMs from command line

Zevgeny

Hi, yesterday I got myself into a silly predicament when the VM I was using to run Xen Orchestra got stuck during its shutdown. It had been set to block accidental shutdowns, so I was unable to force shutdown using XCP-NG Centre, or the regular shutdown command on CLI. As far as I can tell, XCP-NG Centre is unable to toggle the "protect from accidental shutdown" setting, so I was pretty much stuck.

Google search turned up this thread:
https://xcp-ng.org/forum/topic/3885/cli-ssh-delete-vms-that-were-set-as-protect-from-accidental-deletion-in-xo

There's a post in there that mentioned "xe vm-param-cleaner", but that command doesnt exist.

As a guess, I tried this command instead, and it was able to clear the setting so I could do a force shutdown from command line:

xe vm-param-clear uuid=<vm_uuid> param-name=blocked-operations

Just posting this as a reference for future generations.

Maybe there should be a CLI command for "really force shutdown like I really really mean it", that ignores the "Protect" setting? With a confirmation prompt or something?

@Zevgeny Did you succeed to remove the protection with "xe vm-param-clear"?

It didn't worked perfectly for me.

Before I use xe vm-param-clear, I have the following:

[18:28 xcpng02 ~]# xe vm-param-list uuid=37b7a201-eb45-b7de-5ce4-da25b1c7b547 | grep block
                    blocked-operations (MRW): pause: true; hard_shutdown: true; (unknown operation): true; hard_reboot: true; clean_shutdown: true; suspend: true; clean_reboot: true
[18:28 xcpng02 ~]#

Now I try to clean:

[18:28 xcpng02 ~]# xe vm-param-clear uuid=37b7a201-eb45-b7de-5ce4-da25b1c7b547 param-name=blocked-operations
The value given is invalid
field: blocked_operation
value: (unknown operation)
[18:28 xcpng02 ~]#

After, "blocked-operations" looks like this:

[18:28 xcpng02 ~]# xe vm-param-list uuid=37b7a201-eb45-b7de-5ce4-da25b1c7b547 | grep block
                    blocked-operations (MRW): (unknown operation): true; hard_reboot: true; clean_shutdown: true; suspend: true; clean_reboot: true
[18:30 xcpng02 ~]#

In the GUI of XOA, the "Protect from accidental shutdown" is removed but not on the command line.
