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:
