[Bug 1246236] Re: pxe boot from maas fails due to time out
I hit this problem today, and it turned out to be a non-MAAS bug. I was trying to configure a Trusty host with VMware Workstation *and* LXCs sharing the same network. It turns out that the combination of VMware plus Linux bridge interfaces have a bug: if I set up the VM network to be bridged to br0, I can ping hosts on the local network, and I can ping the Linux hypervisor, and I can ping any of the LXCs. I can even DHCP from the LXCs. But I *can't* establish any TCP connections to the LXCs from the VMware guest. My current theory is that somehow the bridge interface is causing packets sentto the LXC from the VMware guest to be discarded at a low level, rather than sent up the stack. I couldn't find any IP Because when I configure VMware to bridge to a physical interface rather than a virtual bridge, it works. Until I disconnect the physical interface. So the bottom line for me was: (1) Have VMware bridge to the physical interface (in my case, it was eth0.100, a VLAN interface) if you want to use bridged mode (2) Use a host-only network (without DHCP, so MAAS can do its thing!) if you want to develop in isolation, without sharing the network with the local LAN - Do NOT bridge VMware to a bridge created with 'brctl' or similar! I added the VMware bridge interface (vmnet1) to the br0 interface I'm using for my MAAS LXC, which may get me the best of both. I'll continue to test this configuration. -- 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

Gavin looked up the ARP issue and it turns out that pxelinux doesn't respond to ARP when in the keyboard read loop and when in the tftp send/recv loop, so that's why there's no ARP response.

[Bug 1246236] Re: pxe boot from maas fails due to time out
Okay, we did a lot of debugging and tracing attempting to find the problem. In the end, it was hardware. I upgraded manually to a newer version of syslinux and pxelinux which /did/ appear to be working, albeit VERY slowly. It seems that the 6.x syslinux network stack is more tolerant of errors, as it seemed to keep limping along. I tested tftp from a MacOS and Ubuntu 14.04 host on the network, and it was able to download the image fine. It turns out that the issue was actually a bad USB NIC that was generating a high amount of RX errors; the ifconfig output showed: RX packets:1380 errors:2758 dropped:1379 overruns:0 frame:1379 We had swapped out the switch, cable and tried other client nodes before realizing it. Moral of the story is that pxelinux's network stack tends to be more sensitive to networking problems, and the symptom is that tftp fails or works very slowly. I'll add that to my collection of release notes. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to maas in 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-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1246236] Re: pxe boot from maas fails due to time out
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/116, 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 Server Team, which is subscribed to maas in 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-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

1 create a new vm node on a 13.10 server, attach the network to a
existing openvswitch, use virtio as nic.
2 install 13.10 onto the vm
3 login to the vm via ssh, and apt-get install maas from archive.
4 modify /etc/maas/import_pxe_files to only download pxe files for
precise and saucy
5 run maas-import-pxe-files
6 create another node by using virt-manager from my laptop, and make it
boot from pxe.
7 run dhcpdum on maas node, we can see dhcp works as expect, and from
the console of the pxe boot node, it shows ip address has been assigned,
trying to get pxelinux.0 from tftp, after couple of seconds, it fails, due

[Bug 1246236] Re: pxe boot from maas fails due to time out
Are you still seeing this problem? I'm seeing this problem now. For me it only started occurring after upgrading MAAS from 1.5+bzr1977-0ubuntu3 to 1.5+bzr1977-0ubuntu4. MAAS is no longer able to PXE boot. To rule out any upgrade/configuration concerns I purged and reinstalled MAAS (wiping out the database, all configuration files, downloaded ephemerals etc. and essentially going again from scratch). This landed me in exactly the same situation. ** Changed in: maas Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to maas in 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-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1246236] Re: pxe boot from maas fails due to time out
Nobody has reported seeing this for a while. I looked at the code and it has a whole second timeout per packet. You would think that this is more than enough over a LAN segment. I also discovered that the tftp client can set its own timeouts (http://tools.ietf.org/html/rfc2349). Given that you see it working from one client and not another, I am suspicious although there's nothing in the tcpdump that shows a timeout option getting set.
