Where does xl debug logging info appear?

Where does xl debug logging info appear?

Hi All.

Following instructions in another thread, I've added a bunch of "log
debug ..." breadcrumbs in the vif-bridge script.

Now I'm trying to *see* those breadcrumbs when I "xl create" a Guest.

But

export XEND_DEBUG=1
xl create test.cfg
ls -al /var/log/xen/*debug*
 ls: cannot access /var/log/xen/*debug*: No such file or directory

xl destroy test

service xend start
xm create test.cfg
ls -al /var/log/xen/*debug*
 -rw-r--r-- 1 root root 835 Jan 24 09:32 /var/log/xen/xend-debug.log

cat /var/log/xen/xend-debug.log
