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: https://dl.dropbox.com/u/98200887/Screen%20Shot%202012-08-15%20at%206.41.12%20PM.png Thanks, Andrew [root@node002 ~]# yum list | grep qemu gpxe-roms-qemu.noarch 0.9.7-6.9.el6 @base qemu-img.x86_64 2:0.12.1.2-2.295.el6_3.1 @updates qemu-kvm.x86_64 2:0.12.1.2-2.295.el6_3.1 @updates qemu-guest-agent.x86_64 2:0.12.1.2-2.295.el6_3.1 updates qemu-kvm-tools.x86_64 2:0.12.1.2-2.295.el6_3.1 updates [root@node002 ~]# ethtool eth0 Settings for eth0: Supported ports: [ TP ] Supported link modes: 10000baseT/Full Supports auto-negotiation: No Advertised link modes: 10000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: No Speed: Unknown!
