I thought it would be cool to have an option to hibernate VMs (instead of shutdown) on PVE host reboot. It's especially handy when VMs require manual intervention for startup.
Any thoughts on this?

Feature request: Hibernate VMs on PVE host reboot
- Thread starter davidand
- Start date
You can hibernate already manually, a general setting to do this on host reboot in already on our internal roadmap.
@Radek Kantor or anyone else it could help, I'm using the following script to automate the process:
I'm quite happy with my scripts, although I would still appreciate this being built in.
Code:
# suspend_and_shutdown.sh
qm list | grep running | awk -F'[^0-9]*' '$0=$2' | while read -r vm_id; do qm suspend $vm_id --todisk 1; done; shutdown -h now
# suspend_and_reboot.sh
qm list | grep running | awk -F'[^0-9]*' '$0=$2' | while read -r vm_id; do qm suspend $vm_id --todisk 1; done; rebootI'm quite happy with my scripts, although I would still appreciate this being built in.
Is there anything new to this planned Feature ?
It would be so great !

Hi,
Here is my solution to hibernate all VMs at reboot or shutdown !
It works for me. Thanks to @davidand for his script example
Go in proxmox shell, you need to be root !
vi /etc/init.d/proxmox
Add this :
chmod 755 /etc/init.d/proxmox
ln -s /etc/init.d/proxmox /etc/rc3.d/S99proxmox
ln -s /etc/init.d/proxmox /etc/rc0.d/K99proxmox
ln -s /etc/init.d/proxmox /etc/rc6.d/K99proxmox
systemctl daemon-reload
systemctl start proxmox
Don't forget to add autostart option in proxmox to the VMs that have to boot on start.
Enjoy !
You can reboot or shutown your server from :
- Physical buttons
- Proxmox Gui buttons
- in shell : restart now / shutdow now

Will this replace the current/standard Proxmox behavior of shutting down the VMs when doing a reboot? Thank you!Hi,

i just tried the script of @davidand , and i think in principle it is working - but I have one problem.
The shutdown of the host process still commands the VMs to shut down in parallel to the hibernate command of the script.
So only the first of my 5 VMs actually will hibernate (the shutdown command for this VM is still issued, but comes to late)
while the other 4 VMs begin their shutdown process before their hibernate commands are issued.
Is there a way to prevent the shutdown commands for the VMs when the host shutdown command is issued ??
If so I couldn't find that.
thx for help.
