I’m trying to achieve the same thing: PXE boot over VLAN.
I’ve modified the VLAN in the SLOT 2 Port 1 Partition 1 interface in UEFI to tag the packages with the right VLAN tag. I also tried doing the same thing for SLOT 2 Port 2 Partition 1, but that didn’t change things. In MAAS I’ve set the VLAN tag for the network. I now end up with our Dell R430 booting with its 10Gb interface with the following output:
After that we wait a couple of minutes and it jumps to a Grub menu, perhaps remnants from the last deployment.
Ideas why it can’t fetch the Netbook image?
