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

From the Omada logs

Yeah pretty strange 😆

Could be related to me using the WiFi adapter instead of the ethernet adapter as mentioned here https://superuser.com/questions/1269435/vm-guest-getting-assigned-same-ip-as-host-when-using-bridge-adapter.

Changing from WiFi to the host adapter for the bridge interface (and rotating the MAC addresses) didn't help unfortunately. Both still get the same IP 🤔
