Hello! Great work guys !

I have a small problem, I want make a small bash script for backup qcow2 files, how can I stop from command line (no web interface) an KVM machine ?

Like vmctl stop/start, but for KVM VMs.

Thanks.

one problem: if you run a win2003 server you cannot shutdown if no admin is logged in. maybe a windows guy out there have a solution for this? on XP its no problem.
 
Thanks, Tom.

For problem with Windows 2003 server, i'm not a windows guy :rolleyes: but on local policy you must allow shutdown without logon.

  1. Start / Run / gpedit.msc
  2. Drill into Computer Configuration / Windows Settings / Security Settings / Local Policies / Security Options. Find the entry named "Shutdown: Allow system to be shut down without having to log on". Double click on it, change it to "Enabled".
  3. Drill into Computer Configuration / Administrative Templates / System. Find the entry named "Display Shutdown Event Tracker". Double click on it, change it to "Disabled".
Now "qm shutdown VMID" works fine.

Enjoy :p

Warning! Remeber, this "hack" enable shutdown button on login dialog ...

Byez.
 
I've tried to run:
Code: 
qm shutdown <vmid>
... but it doesn't seem to shutdown my VMs.

If I run:
Code: 
qm stop <vmid>
... it works just fine, though.

But I'd rather not need to kill my machines that way. Any ideas/suggestions?

does your guest accept anonymous acpi shutdowns? what OS do you run?
 
install acpid.

Code: 
apt-get install acpid
 
I know this is a very old thread but as I can't find a better one, here comes my question:

I'M busy setting up my backup of the proxmox machine with duply and duplicity and duply has a file called pre and one post - I planned to insert "service pve-manager stop" into pre and "service pve-manager start" into post but it only worked half-way:

I manually executed duply from the command line as root and it successfully stopped all VMs but failed to start them. When I re-connected to my screen session, the command service pve-manager start was just displayed on the display without any apparent result. Any ideas?
My next try will be to insert "/etc/init.d/pve-manager start" into post and see if that makes any difference...

Yes, please use

# service pve-manager stop

This stops all VMs and all Containers (we have start/stop ordering now).
