> When we start transferring the kernel over, the machine on the other side stops responding
This is indeed what seems to be causing the problem. Note that we're seeing (a worrying number of) retries in some of the earlier (and successful) transfers. What kind of bridge is being used here? (virbr0 -the bridge created by virsh-, br0, ?). Can you please paste the characteristics of the bridge (by running something like "cd /sys/class/net/virbr0/bridge; for f in `ls *`; do echo -n "$f "; cat $f; done). As described on https://bugs.launchpad.net/maas/+bug/1155556, the default timeout behavior might be the problem here. Can you try changing the RemoteOriginReadSession class in /usr/share/pyshared/tftp/bootstrap.py: change the timeout = (1, 1, 1, 1, 1, 1) to timeout = (1, 3, 7). and then restart the TFTP server? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1246236 Title: pxe boot from maas fails due to time out To manage notifications about this bug go to: https://bugs.launchpad.net/maas/+bug/1246236/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
