Use network bridge as default network in libvirt

Question

I created a network bridge virtbr0 with my NIC enp1s0f1. The bridge gets an ip address from the router via dhcp. i would like to use the bridge as default network in libvirt to also get ip addresses for the respective VM via the router (dhcp server). Is this possible?

Answer 1

Yes, it is possible.

In the virtual machine configuration, use the following kind of interface entry:

<interface type="bridge">
  <mac address="52:54:00:1c:00:3a"/>
  <source bridge="virtbr0"/>
  <model type="e1000e"/>
  <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/>
</interface>

This provides an e1000e network adapter in the virtual machine, which is connected to the virtbr0 bridge.
