libvirt : windows guest vm not receiving IP from dhcp

Hi, i'm trying to run a windows vm with my system. I had to blacklist in connman the network interface vnet and virbr, because when starting a vm, it would drop the connection on the host.

On the windows vm, the network shows up as unidentified, and when trying `ipconfig /renew` in the cmd, i get "unable to contact your DHCP server. Request has timed out.". In virt-manager, no ip address seems to be attribued to the NIC.

here's the xml config of my network :

<network>
  <name>default</name>
  <uuid>64645aac-5869-4a50-8c8f-7d71caea1f0c</uuid>
  <forward mode="nat">
    <nat>
      <port start="1024" end="65535"/>
    </nat>
  </forward>
  <bridge name="virbr0" stp="on" delay="0"/>
  <mac address="52:54:00:6c:c5:6f"/>
  <ip address="192.168.122.1" netmask="255.255.255.0">
    <dhcp>
      <range start="192.168.122.2" end="192.168.122.254"/>
    </dhcp>
  </ip>
</network>

Interestingly, virbr0 seems down :

and it cant seem to be brought back up.
