We had a similar issue. We realized that (in our case) the problem was the Spanning Tree time to converge.
Explication: when PXE boots get an IP from DHCP server, and then when Linux starts, the interface go down and up, and Linux try to get IP from DHCP server again, but fails after 35 seconds aprox. But the physical-switch delays 12 seconds to get the port up agian, and 30 seconds to converge the Spanning Tree. So changing the port configuration to: spanning-tree portfast, o spanning-tree portfast trunk (incase of a trunk), the Spanning Tree delay disappears, and Linux can get the IP from DHCP-server before the timeout ends. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1327412 Title: Delay during PXE Boot, IP-Config gives up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/klibc/+bug/1327412/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
