Yes, you are right. Listen, as the documentation is not very exaustive, can you explain briefly to me how a guest agent works? After installing it via the apt-get on the hypervisor (I am using ubuntu as host system) how can I create a script which would do this? That is waiting for an acpi signal and actually shut down the guest.
And what other operation can you actually do with a guest agent? I would be interested in getting the current amount of memory the guest is using too...as libvirt apis just tell me the max memory allocated. 2014-03-29 15:12 GMT+01:00 Eric Blake <ebl...@redhat.com>: > On 03/29/2014 06:21 AM, Pasquale Dir wrote: > > I am looking at the shutdown method, but if the guest system is a desktop > > system, like for example ubuntu, it just has the effect to show a box > > prompting the user for a shutdown/reboot/ and such. > > > > I could enter the guest and change this default behaviour and it actually > > works..but I'd like for a way to send a shutdown command without doing > so. > > > > Is it possible? > > Guest shutdown is ALWAYS a cooperative action.
