[PTLsim-devel] Problems with devices for domU
Stephan Diestelhorst
Tue Oct 9 12:42:31 EDT 2007
Hi,
I've been playing around with the options for root-devices for a domU in
PTLsim/X and finally have found only the way with tap.aio usable, using the
ptlsim.img from the webpage.
Ideally I'd like to have my domU's root mounted over NFS, but mounting a
physical partition would be nice too.
If I use the attached xm-config file, (xm create ptlvm-smp.sda1 -c) the domain
will eventually time-out and just state
# Error: Device 769 (vbd) could not be connected. Hotplug scripts not working.
looking around in /etc/xen/xend.log, I can however find the appropriate
[2007-10-09 18:02:41 4228] DEBUG (DevController:538)
hotplugStatusCallback /local/domain/0/backend/vbd/8/769/hotplug-status.
(for a full, relevant trace see attachement).
/var/log/xen/xend-debug.log doesn't have any associated lines.
This is on a openSUSE 10.2 dom0 root image, mounted over NFS. OpenSUSE just
uses udev for anything hotplug related and I have checked for the udev rules
with
# udevtest /sys/devices/xen-backend/vbd-1-769/
This program is for debugging only, it does not create any node,
or run any program specified by a RUN key. It may show incorrect results,
if rules match against subsystem specfic kernel event variables.
main: looking at device '/devices/xen-backend/vbd-1-769' from
subsystem 'xen-backend'
main: run: 'socket:/org/freedesktop/hal/udev_event'
main: run: '/etc/xen/scripts/block add'
main: run: 'socket:/org/kernel/udev/monitor'
which suggests that the udev scripts are processed correctly.
I'm (still) using PTLsim's 219 revision, as I have heavily changed the core
models and have not yet found the time to do a merge. As a kernel I use the
provided 2.6.20.3-mtyrel-64bit-xen kernel sources and rebuilt them myself. I
have also rebuitl and reinstalled the xentools inside my dom0.
As this is a custom kernel, I was wondering if anybody else has experienced
similar issues? I've tried different things and queried google and the
mailing lists for days now, but nothing really seems to give any clue on the
problem.
I suspect that some hotplug events are not created properly, but can't nail
that down to anything particular.
I'm happy about any suggestion from your side!
Big thanks in advance!
Stephan
