Key points

  • VMs do not boot with 'Bridged' network mode on Apple M5 Pro.
  • Issue observed with UTM version 4.7.5.
  • VMs boot successfully with 'Host Only' or 'Extended' network modes.
  • Tested with ubuntu-24.04.4-live-server-arm64.iso.

Bridged Network Mode Failure on M5 Pro

Virtual machines are currently unable to boot when configured with 'Bridged' network mode on systems equipped with the new Apple M5 Pro chip. This problem has been identified using UTM virtualization software, specifically version 4.7.5 (118).

Specifics of the Issue

The issue manifests as the VM sitting on the loading screen immediately after attempting to start, without crashing. Debug logs are not generated due to the failure occurring before the system reaches that point. The problem was replicated using ubuntu-24.04.4-live-server-arm64.iso.

Alternative Network Configurations

While 'Bridged' mode is non-functional, VMs successfully boot when the network mode is set to 'Host Only' or 'Extended'. This indicates the problem is specific to the 'Bridged' networking implementation on the M5 Pro architecture within the current UTM version.

Impact on Developers

This limitation affects developers and users who rely on bridged networking for their virtualized environments on the latest Apple M5 Pro hardware. It necessitates using alternative network configurations or awaiting a fix from UTM or macOS to restore full functionality.
