So I am trying to get dual monitors to work on a VM running on UnRaid over VNC. I have never messed much with KVM as a VM, so a bit green on this. Looking at the XML I see the section
<graphics type='vnc' port='5900' autoport='yes' websocket='5700' listen='0.0.0.0' keymap='en-us'>
<listen type='address' address='0.0.0.0'/>
</graphics>
<video>
<model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1'/>
<alias name='video0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/>
</video>
Reading around the web, it seems that I should be able to change heads=2 to get a dual monitor. If I do that, and start the VM, and go to display settings, it still only shows 1 monitor available. Can someone lend a hand on this? Seems like it should be possible.
Maybe add another video tag? Or another alias name? Might have to add another VNC port?
