Things to check for PXE DHCP issues.

* Check for a DHCP helper on the source L3 interface

* Check the KVM host routing. PXE/DHCP to server routing must be in place

* Check L3 interface info, no duplicate IPs, correct mask, static routes, bonding for mgmt

* Check virtual bridging

brctl show – check for MAC address and interface

if no MAC address, run ifconfig virbr0, add the MAC to the XML, destroy the network and restart it

virsh net-edit default
virsh net-destroy default
virsh net-start default

* Check VM XML

virsh dumpxml

* Check network settings vs ovs-vsctl list – add any missing ports
