Red Hat Bugzilla 1449265 0 high CLOSED Libvirt uses a bad QEMU device for the <serial> XML tag on s390x 2022-05-16 11:32:56 UTC

Description Dan Horák 2016-09-15 16:37:26 UTC 
The test-suite for libguestfs fails on s390x with an "invalid device" from qemu. It could be coming also from libvirt, because I could find the "isa-serial" string in libguestfs.

Comment 1 Richard W.M. Jones 2016-09-15 16:59:19 UTC 
The good news is that libguestfs builds fine on S/390.  However
it fails this sanity check so it won't work at all.

This is basically a libvirt bug - it is passing a non-existent
device to the guest.

Here are some things you can try in a local build of libguestfs.
You will first need to build libguestfs itself.  You should follow
the instructions in the link closely.  The tests below assume you have
already built libguestfs and are operating in the build directory.
NB do not attempt to use 'make install'.

  http://libguestfs.org/guestfs-building.1.html

    - - -

The tests:

(1) make quickcheck LIBGUESTFS_BACKEND=libvirt

(should replicate the above bug)

(2) make quickcheck LIBGUESTFS_BACKEND=direct

This directs libguestfs to run qemu itself ("direct"-ly).  This may
or may not work.  Since it is using a completely different backend
it could hit a different set of bugs.

https://github.com/libguestfs/libguestfs/blob/master/src/launch-direct.c
https://github.com/libguestfs/libguestfs/blob/master/src/launch-libvirt.c

If test (2) works, then:

(3a) make check -k LIBGUESTFS_BACKEND=direct
     find -name test-suite.log | xargs grep ^FAIL:

Runs the full test suite, and then prints out the failures.  Please file
bugs about anything you find.

If you are interested in automated testing then most tests allow you
to set environment variables to skip tests, but you usually have to
examine the test code to find out what the skip variable is.

(3b) make check -k LIBGUESTFS_BACKEND=direct LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1

This runs the full test suite with additional debugging enabled
which is a good way to track down specific problems.

    - - -

If you have plenty of patience, then:

(4) make check-slow LIBGUESTFS_BACKEND=direct

Runs an extra set of long-running and/or resource-intensive tests.
Comment 2 Dan Horák 2016-10-06 12:06:13 UTC 
(1) yes, the above bug is replicated

qemu-system-s390x: Warning: global kvm-pit.lost_tick_policy has invalid class name
make: *** [Makefile:2407: quickcheck] Alarm clock
Comment 4 Dan Horák 2016-10-06 12:10:14 UTC

My conclusion is: it doesn't like the SCSI device type for the disks.
Comment 5 Richard W.M. Jones 2016-10-06 13:38:37 UTC 
In comment 3 what is likely to be happening is that the
appliance kernel is crashing or hanging.  However because
we cannot see the console messages, there's no real clue
exactly what went wrong.

In comment 4 it gets a lot further than I thought, but really
you can't just run the qemu command directly.  See comment 1
for how this can be properly debugged and fixed.
Comment 6 Richard W.M. Jones 2016-10-06 13:40:07 UTC 
Which is to say you should fiddle around with src/launch-direct.c
fixing the parameters until the appliance can boot with console
messages enabled.
Comment 7 Dan Horák 2016-10-06 14:19:00 UTC 
I was wondering how the output should look like, so I took some hackish steps to get it from the command line. Should I check eg. the x86 build logs or is there other place to look?

Right now I think there are 2 issues - no console output (at all, no kernel messages, etc) and root disk not available because scsi is not understood.
Comment 8 Richard W.M. Jones 2016-10-06 15:22:51 UTC 
Created attachment 1207973 [details]
libguestfs-test-tool output

After the qemu command is printed, you'd expect to see kernel
boot messages.  There may also be some firmware messages before
those if s/390x has such a thing.  Attached is the output
on x86_64 from:

Yeah I guess see if you can find a working qemu invocation for fedora s390 and work backwards from there. There may not be a working command line though... I though I've heard that qemu doesn't emulate the s390 machine/cpu/something that fedora/rhel s390 are built to run on

That's a virt-install issue, fixed upstream now:

    virt-install: Fix error checking extra_args
Comment 11 Richard W.M. Jones 2016-11-02 15:44:59 UTC 
I wasn't able to make our images boot.  The closest I got was:

  The Linux kernel requires more recent processor hardware

using the command:

I think this is likely due to the missing STFLE emulation in QEMU. Patches are currently discussed on the mailing list:

https://lists.gnu.org/archive/html/qemu-devel/2017-03/msg00239.html
Comment 14 Cole Robinson 2017-05-04 18:14:58 UTC 
I just played with this a bit. qemu s390 doesn't actually have anything that maps to libvirt's <serial> device, it only has <console> devices, target type=sclp or type=sclplm. Libvirt fills in an appropriate s390 default for <console> XML

So I think for the s390 case, libguestfs needs to s/serial/console/

There's some relevant info here too: https://specs.openstack.org/openstack/nova-specs/specs/kilo/implemented/libvirt-kvm-systemz.html
Comment 15 Richard W.M. Jones 2017-05-17 11:56:11 UTC 
I posted a few patches which make this work with libguestfs:

https://www.redhat.com/archives/libguestfs/2017-May/msg00066.html
https://www.redhat.com/archives/libguestfs/2017-May/msg00067.html
https://www.redhat.com/archives/libguestfs/2017-May/msg00068.html

However I still don't believe that libvirt is *right* here
(or perhaps the problem lies with qemu, the kernel or the s/390
architecture itself).  All those #ifdefs represent pointless
complexity IMHO.

Unless you explicitely need a serial port ... can't you simply always use a <console> instead? If I get the libvirt documentation right (https://libvirt.org/formatdomain.html#elementCharConsole), the <console> device will create the right real device automatically for you, depending on the machine type and hypervisor. So on x86, you should get a serial port with it, while on s390x, you should get an sclp console instead.

What's the current state and outlook of this? OpenStack wants to remove the NBD fallback in favor of always using libguestfs [1] and with this bug here OpenStack on s390x will lose functionality.

All the patches mentioned above, and a couple of additional fixes, where done in 1.37.14.

An additional fix for the direct backend (commit 5b60dd4eff02f48d344bcdad0d4bad4676ca9168) is available in 1.37.22.

Will this get backported into the Ubuntu 16.04 LTS ? Currently I see version 1.32.2:

root@z-lpar:~# apt-cache policy libguestfs-tools
libguestfs-tools:
  Installed: (none)
  Candidate: 1:1.32.2-4ubuntu2
  Version table:
     1:1.32.2-4ubuntu2 500
        500 http://ports.ubuntu.com xenial/universe s390x Packages

If it doesn't get backported, will it be available in the next LTS release Ubuntu 18.04?

Between 1.32.x and 1.37.x there were lots of changes, and backporting it (even if we would) is not an easy option.  Generally speaking though, we do not control what goes in Ubuntu, and from what I know there is no active maintainer of libguestfs in Ubuntu, so I'm afraid there is basically no chance this is going to be backported.

As mentioned above, this depends on the Ubuntu packagers themselves.  Ubuntu usually gets libguestfs directly from Debian, and Debian follows only stable series (the even series, e.g. 1.32, 1.34, etc).

Closing since this is fixed upstream.
