Description Richard W.M. Jones 2011-01-28 06:00:56 EST
+++ This bug was initially created as a clone of Bug #673477 +++

When debugging virt-v2v problems, the most useful debug information is normally LIBGUESTFS_TRACE. Occasionally LIBGUESTFS_DEBUG is also useful, but less often. However, it is a problem when these 2 outputs are mixed. DEBUG is significantly more verbose than TRACE (about 100:1 iirc), and it is not trivial to separate their outputs.

It would greatly simplify debugging instructions to users if we could simply request both outputs. The result should:

* Be simple to view mixed, chronologically
* Be simple to separate

Adding a grep-friendly string to TRACE and/or DEBUG output would achieve this. It doesn't really matter what the string(s) is/are.

That patch broke a regression test.  This commit is

Ugh ignore comment 4 that, my mistake.
