Resume from hibernate failed: got timeout. How to increase 300sec timeout?

[Vasily Poterjyko]

Restoring a heavy machine with >270Gb RAM. The state of the machine is on SSD disks, reading the entire volume of this file takes less than 300 seconds, but I still get the timeout of the machine restore operation from hibernate.
How to increase VM recovery timeout?
I also want to note that saving the state of the virtual machine to disk took more than 11 minutes.

there is sadly no mechanism currently to manually increase the timeout, but
you could temporarily edit the file in '/usr/share/perl5/PVE/QemuServer/Helpers.pm' to increase the $timeout = 300; to e.g. 600
(note that you must restart the pveproxy and pvedaemon after editing that file, and this change will be overwritten on the next update)

you can open a bug report for configuring a manual timeout: https://bugzilla.proxmox.com

Thank you very much for your reply! I'll check out what you suggested for increasing the machine recovery timeout from hibernation.

I created a feature request. https://bugzilla.proxmox.com/show_bug.cgi?id=3911

Increasing the timeout in Helpers.pm did not help me upon first try. I did not dig deeper. However, I was able to see the /usr/bin/kvm command in the "Task Viewer" window when I double clicked on the "VM 129 -- Resume" line in the task log. Running this from the command line then ran to completion succesfully.

Thanks a lot.

This has worked for me.

1.) Copy the /usr/bin/kvm command from the failed log entry.
2.) Open a shell and execute the command.
3.) Wait very long. You should see the rising RAM usage.
4.) If the command has finished the VM should run again.
But the UI still shows a different icon.
5.) Remove the Hibernation VM State image file from the "Hardware" section of the VM. This should fix the GUI inidicators and buttons.
