[Qemu-devel] [Build bug] Problem checking out submodules

[Lucas Meneghel Rodrigues]

Hello:

In the daily qemu.git autotest run, I started to see the following 
problem while checking out the qemu.git tree and checking out the 
submodules:

Can someone please take a look at fixing this? Thanks!

It looks like a recent commit to update the version of SeaBIOS used
broke the build as the qemu mirror hasn't been updated yet. You can work
around it for now by patching .gitmodules:

commit 7149af13dd5600b27dac90235e60ff91d0468636
Author: Alex Bennée <alex@bennee.com>
Date:   Tue Oct 1 16:51:38 2013 +0100

    .gitmodules: use upstream SeaBIOS repo to fix submodule init
    
    Currently master is broken as the wanted commit doesn't exist in
    qemu's mirror of SeaBIOS.

Ok, thanks for the explanation. Local patching is not really a scalable 
option when performing automated testing though. I'll keep the daily job 
running, and when the mirror is updated, the failures will stop.

Oh I just noticed that. Is this Stefan's buildbot stuff or an internal
auto-test set-up? I only ask because I noticed this while testing my
Travis patches. I'm trying to get a feel for what CI type tasks are
running in QEMU world, both public and internal to companies.

I'll be submitting a patch tomorrow when I post the next version of the
Travis patches up to the mailing list.

That's an internal autotest test grid. Once a day we check the latest 
qemu master and run sort of a smoke style test job, although it's not 
so, 'smoky', since it takes about a couple of hours to run. Tests covered:

1) Installing Fedora 19 on a host
2) git clone the latest master
3) Install a RHEL 6.4 guest from kickstart
4) Basic boot, reboot, single host migration using tcp, unix socket, fd 
and exec migration
5) Install a Windows 7 guest from an unattended XML, using the latest 
virtio drivers that our windows drivers team releases.
6) Perform the same tests outlined in 4)

I hope it gives you a better idea of what's going on.
