RE: [Xen-devel] Hotplug scripts not working... xen/ia64 domU stopped wor
Sorry for the delay. I reinstalled from scratch and started
searching from the last working version. (See status below.)

Definitely no hotplug or udev events going into /var/log/messages.

By "put logging into" do you mean adding a '-x' at the end
of the first (bin/sh) line? If so, where is the logging going?
(not to the console nor to /var/log/xend.log...) Sorry...
it's been awhile since I've done script debugging and it's
definitely a lot different than hypervisor debugging :-}
Status: cset 8006 and cset 8029 both work fine. Cset 8054 fails
with the "Hotplug scripts not working" message. This narrows
the field considerably. Cset 8043 and 8049 look suspicious.
For 8043, I thought maybe there is a dependency on the newly
added arch_memory_op call, but flagged that for ia64 and it
doesn't appear to be the case. Cset 8049: This isn't intended
to stop use of a disk-in-a-file via the loopback driver, is it?
The xend.log and /etc/xen/xmdefconfig are the same as the last.
I'm building 8048 now (takes about an hour).
Thanks for all the help. I'm getting closer...
Dan
