Hallo
I have a kvm vm that I am attempting to boot from pxe. The dhcp works perfectly and I can
see the VM in the pxe server arp. but the tftp just times out. I don't see any tftp
traffic on either the physical host or on the pie server. I am using a bridged interface.
I have tried using several virtual nic drivers, several different mac addresses and
several different ips. on the physical host I can get the pxelinux.0 file from the pxe
server via tftp and can clearly see that traffic with tcpdump.
Ive tried using various virtual interfaces.
I can pxe boot my physical hosts with no problems.
I can tftp fine from the physical host and see the traffic with ethdump
Here is the terminal output from the VM:

Thanks,
