Linux VM fails to PXE boot on MacOS host

[sorin]

Virtualbox (5.2.18) + extensions installed on a 2017 iMac with MacOS (OSX) 10.14 Mojave and it seems impossible to make the VM get an IP address from my DHCP server during PXE booting.

I tried all possible combinations for configuring the network adapter for the VM but still it fails to get the DHCP IP. I even checked the DHCP server logs and I am sure that the IP used by the VM never reached it.

The config I was expecting to be working:

Bridged Adapter: en0 (this is the LAN of the iMac) Adapter Type: one of Intel ones (but tried all 6 possible alternatives) Promiscous Mode: deny MAC Address: a generated one Cable Connected: Checked.

I am not sure if this problem is specific to MacOS Mojave or the Ethernet board in iMac as I did not had the chance to test with other versions.
