In virt-manager, the 'open' button opens the screen of your guest. If your 
screen is blank, press a button to wake-up your screen. If still nothing 
appears, maybe your guest doesn't boot correctly??

To use the shutdown function, acpi needs to be enabled. On some OS's this isn't 
the standard setting and you will have to enable it yourself. But if your guest 
doesn't boot correctly, the acpi deamon (or equivalent) isn't started yet...

You can look for the ip with tools like tcpdump... But again, if your guest 
doesn't boot correctly, chances are that the network of your guest isn't up 
yet...

Onderwerp: [libvirt-users] Can't figure out how to restart VM after making 
config changes in virt-manager

I finally figured out my VNC configuration, so I can now run virt-manager to 
inspect and manipulate my VM.

I initially created the VM with "virt-install", but I haven't been able to see 
the console or do anything with it.

When I ran virt-manager, I tried to configure the vcpus (1->4) and change the 
boot order (cdrom, then disk, as I created the VM with an ISO).

When I made these changes, virt-manager said they would take effect on the next 
restart of the VM. So, then I tried to restart the VM from virt-manager.  The 
"Run" button is disabled, so I assume that means it detects that the VM is 
running.  I've tried clicking "Shut Down" and selecting "Reboot" from the 
dropdown, but neither of those seem to do anything.  I've tried to view the 
console window, but I've only ever seen a black screen there.

I believe some people mentioned that I should try sshing to the VM.  I would do 
that if I could find an IP address or hostname that appears to correspond to 
this VM.  The obvious, using the VM name, didn't work.

I'm not sure what to do here.
