Bulk Hibernate?

[harmonyp]

My node needs to be rebooted how can I bulk Hibernate (suspend to disk) lots of VMs?

On a side note are there any risk of data loss with hibernation? or any known issues

Hi,

My node needs to be rebooted how can I bulk Hibernate (suspend to disk) lots of VMs?

AFAIK, there is no such feature at the moment, you'd need to do it with a script. Feel free to create a feature request for it: https://bugzilla.proxmox.com/

On a side note are there any risk of data loss with hibernation? or any known issues

None currently known. Under the hood it's essentially the same mechanism as taking a snapshot with RAM and rolling back.

I have two different machines both using ZFS I can't figure out why one of them instantly hibernates and restores but my other machine takes 30-60 seconds. Any ideas? Both node VMs are NVMe and same disk settings (SCSI etc)

Or maybe a way to speed it up? precreate snapshot maybe

Can you post the VM configs, i.e. qm config <ID>, and the hibernation task logs for both of them? The output of pveversion -v for context would also be helpful.

the feature is not requested that often and (partially because of that) not high-priority at the moment. Such features can take a while to get around to. Note that it's about bulk hibernation "only" since 2019, before it was about bulk pause. You can CC yourself to the feature request to indicate that there is interest and I think that will also send a mail to the assignee.

I know it's quite old thread, and I haven't commented at that moment, but I keep find myself from time to time in the point when this bulk hibernation option would be very handy to have.
