[Xen-devel] Re: Timeout connecting to device
I didn't see any responses to this query. I also see:
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=176
which is essentially the same issue. Do VBDs work for anyone on the list?
It sounds like
> XENBUS xs_read_watch: 0
is an indication of the fact that after the right entries were made in
xenstore (I can see them on /var/lib/xenstored/store/domain), but xenbus
is not able to read events?
# find . -name *end
./a9b503a7-2494-409f-9e06-2bd1f9283953/device/vbd/768/backend
./45194ebb-4029-4131-9013-d17cd3dbc828/device/vbd/768/backend

./53ffa08b-5f90-45a4-9671-8d6fff7f8509/backend/vbd/45194ebb-4029-4131-9013-d17cd3dbc828/768/frontend
Couple of questions:
- is there a way to debug xenstored? It doesn't seem to be logging much.
- Could we add some debug flags elsewhere as well (xenbus with debug=1?)
to make debugging problems of this nature easier?
A golden "working" log file would also be useful so we can compare our
logs against it..
