# Install dependancies, virtmanager, etc.
apt-get install --no-install-recommends qemu-system libvirt-clients libvirt-daemon-system virtinst qemu-utils libosinfo-bin

# To get a list of IDs for --os-variant:

Okay then a couple of things:

# Modify windows10 domain settings to change to vnc & port
virsh edit windows10
  <graphics type='vnc' port='5950' autoport='no' listen='0.0.0.0'>
    <listen type='address' address='0.0.0.0'/>
  </graphics>
  # Boot device must be changed to cdrom:
  <os>
    <type arch='x86_64' machine='pc-q35-4.2'>hvm</type>
    <boot dev='cdrom'/>
  </os>

# Then destroy (stop) VM and start again (reboot wont apply setting change)
virsh destroy windows10
virsh start windows10

# Then INSTALL Windows

# then:
virsh edit windows10
  change back to hd
  <os>
    <type arch='x86_64' machine='pc-q35-4.2'>hvm</type>
    <boot dev='hd'/>
  </os>

# Then destroy (stop) VM and start again (reboot wont apply setting change)
virsh destroy windows10
virsh start windows10

# Output of this needs to show 0.0.0.0:5950 (nice hat) to show that its listening on all interfaces
netstat -tulpn | grep 59
  tcp        0      0 0.0.0.0:5950            0.0.0.0:*               LISTEN      26523/qemu-system-x
  #redacted

#but it will actually ask you to boot from cd-dvd so not to actually worry about changing it - it will make it a few seconds faster to boot though, so change it after install complete

You may need to add a rule through iptables, or just disable it (NO DONT - BAD IDEA!!!) https://serverfault.com/questions/129086/how-to-start-stop-iptables-on-ubuntu

Autostart settings:

virsh autostart windows10
virsh autostart windows10 --disable
