Fedora 18 host and two Centos-6.3 guest: how to shutdown guest?

[Dario Lesca]

I have setup on a libvirtd Fedora 18 up to date two centos-6.3 server
(web and mail), but it seems that when I shutdown f18, the two hosts are
power off without shutdown.

How to ensure that the two guests are suspended, hibernate or shut down
properly? like Centos 6.3 host do?
I have missing some things?

Many thanks.

I think all you need to do is to enable the libvirt-guests service.  It is part of the
libvirt-client package so you should have it installed.

systemctl enable libvirt-guests

I do NOT use that feature.  I manually shutdown guests.  That service basically suspends
the VMs to disk... and if I have a VM with 32GB of RAM, it has to write a 32GB dump file. 
If you have a few of those, it can take longer to suspend and restore than simply shutting
down the host and starting it again.

On guests with small/reasonable amounts of RAM, it probably is nice to have turned on.

TYL,

Thanks Scott, this is the my problem:

simple: the service is not enable.

Via /etc/sysconfig/libvirt-guests I have see it's possible to set if
suspend (default) or shutdown (warning!)

In my case is good suspend... then I have enable and start the service.

Many thanks
