qm suspend shows no result

[holgihero]

Hi all,

what exactly should be the effect of using "qm suspend <vmid>"?

What kind of suspend mode should the vm run into?
I tried the command on some vm (win or lin) with no effect. They run happily ever after...

My goal is to send some machines to a defined state which do not react to "qm shutdown" in case of power failure...

OK, I was misleaded by "qm status" which shows a state of "running" for a suspended machine. Which IMHO is wrong and should be corrected if possible.
The vm's DO go to suspend mode...

So my question is now: Will a suspended state behave well after shutdown and restart of the host? Will it resume propperly? What happens with vm memory? Will it be lost?

Regards, Holgi

as it does not suspend to disk the state will be lost if you reboot the host.

Suspend-to-disk is simple and stable with kvm. If more than a few people are interested i could implement it and send patches in my next open timeslot. Design question: would you like to give a hibernation filename or should it be autogenerated? Would you like to see a suspendonreboot init.d script to suspend on host shutdown and resume on startup?

Please wait until we release 2.0 beta - It make no sense to impl. that in 1.X
