Error in xen-unstable

[Roger Pau Monné]

Hello,

When trying to create a domu (xm) with xen-unstable on NetBSD i get
the following error:

Error: Device 51714 (tap) could not be connected. Hotplug scripts not working.

I've looked at the xend, and I don't see any error, here is the extract:

It seems like xen is not able to detach the devices, but I don't know
why the domu fails to start. Hotplug scripts are inside the
xen/scripts folder, they are the same found on Xen 4.1.1, which I know
worked. Is there any change in xen-unstable that might break the
scripts?

Here is the xm info of the system:

Does netbsd even support tap devices? I know it doesn't have blktap, but
does it have some sort equivalent?

Christoph, do you know anything about the issues Roger has been seeing?

Ah, right, that name is confusingly overloaded :-(

It is a block backend in userspace which handles more complex disk image
formats like VHD (compared with Linux's blkback which only handles
exposing raw block devices but is entirely in kernel).

So it should work if Roger removes any PCI passthrough stuff from his
guest cfg?

Does NetBSD have pciback? Is code needed in libxl to support it
differently from the Linux pciback?

I presume that at least the xend stuff has been that way forever, or did
something change recently?

Patches gratefully received.

I think, this can be implemented on top of puffs:

http://en.wikipedia.org/wiki/PUFFS_%28NetBSD%29
http://www.netbsd.org/docs/puffs/

libxl uses tap:aio on NetBSD from the beginning for raw files.
It should turn back to use disk type file as xm does
so that NetBSD's blkback is used again.

Yes.

Well, mainly the interaction with the OS itself is different (how to 
receive the PCI information and the ioctl's to talk to the devices).

PciUtil.get_all_pci_devices() is not portable. In pkgsrc we have this
patch for years which is not acceptable shape for upstream:

http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/sysutils/xentools41/patches/patch-ba?annotate=1.1.1.1&only_with_tag=MAIN

Perhaps, blktap exposes what looks like a raw device to the guest
though, rather than a filesystem (perhaps PUFFs isn't constrained to
just filesystems though. I didn't dig too deep)

Sounds like that should be pretty easy to fix on top of Ian Jackson's
recent patch 23685:0a70aeba14e2 "libxl: sane disk backend selection and
validation". Or perhaps it is already fixed by a combination of that
and/or 23675:00d2c5ca26fd "libxl: do not use tap disk backend other than
for raw and vhd"?

Is that the only one?

Presumably this can be done more cleanly as:

Re: Error in xen-unstable

[Roger Pau Monné]

Hello,

Thanks both for the help, I was able to boot PV machines using the old
toolstack (xm), xl still show the same odd behaviour. I'm able to boot
a PV machine only one time, after I shut it down I have to reboot the
system, I think because xenstore is not properly cleaned when the
machine is shut down. Here is my xenstore-ls before launching any
domu:

Note that devices 51714 and 51713 are still listed in the dom0, and
when I try to start the domu again, I don't see anything in the
console, and xm create freezes. I'm trying to debug this, but since
I'm new to xen, it's kind of complicated. If someone could point me in
the right direction I will try to do my best to fix this. Anyway, I
will keep on working on this as long as I have time to do so.

Thanks, Roger.

The presence of all these entries for dom0 is a bit odd. I doubt it is
related to your issue but it'd be worth clearing them out, or perhaps
arranging for your xenstore tdb to be nuked on boot.

A dom3... I think having a good clean out of xenstore on boot would be
wise (or at least remove some of the woods so we can see the trees!)

This appears to be the current actual dom0 entry.

All seems sane enough.

I imagine that a simple xenstore-read can read those nodes just fine
throughout?

If you manually xenstore-rm the backend directories does it unwedge
itself? (obviously not a solution but might provide an interesting data
point).

FWIW I don't see anything like this on Linux dom0, but that doesn't
necessarily rule out some sort of generic issue. I'm not all that
familiar with how NetBSD dom0 is setup (for example I'm not sure what
role xenbackendd plays)

I think clearing out your xenstored db (/var/lib/xenstored/tdb on Linux,
not sure about NetBSD) and rebooting would be worthwhile just to rule
out any corruption or whatever. Note that on Linux we remove this in the
initscript (apparently since 21552:de101fc39fc3 when the xencommons
stuff landed), perhaps (most probably) doing the same on NetBSD makes
sense?

One other thing which might be useful to try would be to switch to the
ocaml xenstored because it will log various xenstore interactions
in /var/log/xenstored-access.log. It's a bit of a long shot but might
help spot what's going on (or it might magically fix the problem :-D).

It might also be worth checking the patches in NetBSD's ports, in case
there is an interesting fix in there...

Maybe you posted it before but can you repost your guest config?

You are having a different issue with xl, is that right? xend is not
exactly maintained these days.

Re: Error in xen-unstable

[Roger Pau Monné]

Hello,

I've been doing some more research, and disabled the execution of
scripts in xenbackendd, so no action is performed to disconnect/remove
devices from xenstore, the trace from xenbackendd shows the following
when shutting down:

read from xen watch: /local/domain/0/backend/vbd/3/51713/state

read from xen watch: /local/domain/0/backend/vbd/3/51713/state
status of /local/domain/0/backend/vbd/3/51713: 5

Devices seem to be in the close states (6), but then something sets
them again to closing (5). That's where the problems comes from, when
xenbackendd reads a state 6, it closes the device and deletes the
entry from xenstore, but another process is setting the state to 5, so
the device is added again to xenstore and prevents to boot the machine
again (I can always delete the device with xenstore-rm and boot again
with no problem). The output from xenstore-ls (if no scripts are
executed to detach/remove the devices):

Someone has a clue of what process would set the state of the device
to 5 (closing) after setting it to 6 (closed)?

I've applied two patches to libxc, but they are related to grant
tables, so I don't think they have anything to do with this:
