[CentOS-devel] koji build failure

[George Dunlap]

Sometime back in January I submitted the then-current Xen4CentOS dom0
package to build in the CBS for C6, and it worked out of the box:

https://cbs.centos.org/koji/buildinfo?buildID=601

After finishing up my mad month of writing slides, my holiday, and
then clearing my developer backlog, I tried again with the most recent
kernel version, and it failed:

https://cbs.centos.org/koji/buildinfo?buildID=851

I looked at a diff between the two specfiles, and couldn't see
anything that might have prompted this change; so I went back to try
to build the same SRPM I built back in January; and it also failed in
exactly the same way:

https://cbs.centos.org/koji/taskinfo?taskID=8943

I did subsequently build a new set of xen packages, so it's not an
issue with the build system in general, just an issue with the kernel
package.

The actual error message is this one:

DEBUG util.py:333:  Executing command: ['/usr/bin/yum',
'--installroot', '/var/lib/mock/virt6-el6-build-1391-2327/root/',

I feel a bit dumb here, but I really have no idea what koji or mock
are doing, so I have no real idea how to proceed to debug what's going
on here.  Can anyone give me a hand?
