It is sometimes counter intuitive for a desktop user that the virtual machine
continues to run when they left the console viewer application. They are used
that when they close an application all the resources being used by it are also
freed up, and from their perspective, the console viewer is just one more
application running.
Hmm, I don't know if I buy this. Closing a VNC client window doesn't shut down
the remote machine, nor does exiting an SSH connection.
Yes, but in these cases the user is probably accessing a remote machine,
so machine resource utilization is generally not a concern of the user.
The general desktop user whose necessity I am trying to address is just
accessing VMs on their own personal system. And, unfortunately, they
usually get upset by the fact that even though they are not using the
VM, it is still consuming the machine resources.
And doing virt-manager
--uuid <blah> doesn't auto-start an inactive VM so users are forced to
recognize this concept IMO.
Well, that would be my next patch. :)
Actually I was thinking to contribute a similar option to autostart the
VM when the console is opened and the VM is not running. I was just
thinking whether I should use the same option or another one to do that.
There's also the issue that reliably shutting down a VM in a safe way is hard:
I agree, and that's why I am using the routine that is already available
in virt-manager, which can show an error message if the shutdown
procedure fails somehow.
shutdown often doesn't do what's expected, and destroy is potentially
dangerous. If we just kick off 'shutdown' on exit then the user may not notice
for a long time that the VM never shut down.
I think I'd be more comfortable with just recommending a wrapper script if
someone really wants this functionality, it's basically:
virsh start <vmname>
virt-manager --no-fork --uuid $(virsh domuuid <vmname>)
virsh destroy <vmname>
I thought about a wrapper script, but it would only cover the case in
which a user doesn't open the manager window at all.
In a nutshell, I am not against your comments (I personally share lots
of them, actually), but I am used with VM management work and the
feedback from real desktop users is not good on that regard.
