Hibernation?

[Misogynist]

Hello developers.

First of all: great product, works really well on my machine at home, and we're thinking about using it at work, instead of VMware.. So job well done!

There's just one question I have: Are you thinking about implementing functionality for hibernation?

I installed hibernate using apt, and it says the kernel doesnt support hibernation.

I think that would be a great thing, especially in times of growing interest in ecological topics.

An answer would be highly appreciated. Thanks in advance.
I'm not sure how tricky it is freezing all the guests with the main system, but as far as I imagine it, they shouldnt even notice it. I could be wrong there though..

I am not sure if I understand you correctly - you want to do server virtualization and you want to use hibernation?

For me a server has to run 24/7, so pls explain your usage scenario to get a better understanding here.

Well, sure, a box for virtualization has to run most of the time, but there are scenarios where it might be able to hibernate.

For instance on weekends or at night.
I would set flags from the different guest machines, to make sure noone is in need for the host, then it would hibernate.

All the clients that are using the server, have the possibility to wake it up, using wake on lan.

I'm almost finished preparing everything for that task, I just need the hibernation part.

I hope that makes sense to you..

why don´t you just power off at night/weekend - and wake on lan? hibernation could cause a lot of issues (but its already in)

I just tested on fresh install (just had to add apt-get install hibernate) and the host shuts down after issues the command:

hibernate

but I saw no resume afterwards. so looks not really useable yet ..

Yeah - I'm shutting down and WOL right now .. hibernate would just be a major increase in performance.


Oh and: try hibernate-ram - that's where I'm stuck.

As I said: this was just an easy example - in reality I want to put it into hibernation mode whenever it's not used - which could be at any time..
