Bridge network guest receiving same ip address from external dhcp server

**Describe the issue**
When I configure
- Two guests with bridge networking
- Both guests have cloud-init installed and dhcp on the first interface

When booting both machines, both receive the same IP address from the dhcp server! 😅 The MAC address of the network cards is different inside of UTM.

**Configuration**
* UTM Version: 4.6.4
* macOS Version: 15.2
* Mac Chip (Intel, M1, ...): M2 Pro
