Public bug reported: Attempting to PXE boot both the 12.04.3 and 14.04 Live images. PXE boot works normally (PXE Menu, select desired image, image begins loading), then the boot process hangs while IP-Config attempts to get an IP address:
IP-Config: eth0 hardware address e0:db:55:0c:34:7e mtu 1500 DHCP IP-Config: eth1 hardware address e0:db:55:0c:34:80 mtu 1500 DHCP IP-Config: no response after 2 secs - giving up IP-Config: eth0 hardware address e0:db:55:0c:34:7e mtu 1500 DHCP IP-Config: eth1 hardware address e0:db:55:0c:34:80 mtu 1500 DHCP IP-Config: no response after 3 secs - giving up These lines appear very quickly (5 seconds has NOT elapsed), after about a minute, we get this: IP-Config: eth0 hardware address e0:db:55:0c:34:7e mtu 1500 DHCP IP-Config: eth1 hardware address e0:db:55:0c:34:80 mtu 1500 DHCP IP-Config: no response after 4 secs - giving up Some time later, this: IP-Config: eth0 hardware address e0:db:55:0c:34:7e mtu 1500 DHCP IP-Config: eth1 hardware address e0:db:55:0c:34:80 mtu 1500 DHCP IP-Config: no response after 6 secs - giving up Until finally, this: IP-Config: eth0 hardware address e0:db:55:0c:34:7e mtu 1500 DHCP IP-Config: eth1 hardware address e0:db:55:0c:34:80 mtu 1500 DHCP IP-Config: no response after 9 secs - giving up IP-Config: eth0 hardware address e0:db:55:0c:34:7e mtu 1500 DHCP IP-Config: eth1 hardware address e0:db:55:0c:34:80 mtu 1500 DHCP IP-Config: eth0 guessed broadcast address 172.25.11.31 IP-Config: eth0 complete (dhcp from 172.25.10.20): (snip) While watching the DHCP server logs, Ubuntu is either not sending a DHCP Discover at times, or is not replying back with a DHCPRequest during these sessions, presumably ignoring an response from the DHCP server. >From the initial booting of the system via PXE, to when Ubuntu finally shows the desktop, almost 12 minutes will have elapsed. I am seeing this same behavior on both 12.04.3 and 14.04. After finding a number of similar erros via Google and no real resolution, I have opened this bug. The system experiencing this issue has multiple ethernet interfaces (actual HW, not a VM), some Google found solutions suggest hard coding DEVICE=eth0 in /etc/initramfs-tools/initramfs.conf, however this isn't acceptable as a system attempting to PXE boot may be using an alternate port for the network. I have found what looks to be a very similar bug filed for Debian, #584583, which also contains a patch for this issue (under Debian). I have no problems in PXE booting to various Windows, RedHat, Centos, or Fedora OSs. Ubuntu is the only Live OS that I'm attempting to boot at present.
