Hi.

Previously I was using debian 8 to compile my xen 4.6 with hvm
stubdomain support. We recently switched to ubuntu servers, thus I
needed to change my compilation environment not to have lib dependency
issues.

My problem is: I get the staging 4.6 xen
(http://xenbits.xen.org/gitweb/?p=xen.git;a=snapshot;h=8e89d43867922abaa67e894938c655a6fa82affe;sf=tgz),
installed all required prereqs for my compilaton environment, but during
compilation I get errors (I do not get them using debian 8). I'm sure
that all prereq is met, becasuse ./configure runs correctly, I'm using
--enable-systemd --enable-stubdom )

Most of the problems could be solved by dirty hacks for myself, but I
belive they require some attention of qemu/xen developers to make
compilation work under ubuntu 16.04 out of the box:

The first issue

/usr/src/xen-staging-4.6/tools/qemu-xen-traditional-dir/vnc.c:2180:
undefined reference to `gnutls_kx_set_priority'

could be solved by applying these patches over the auto downloaded qemu
sources:

https://gitlab.com/johnth/aur-xen/raw/f9d0b40e240add9a136483a450c6a1b39a685808/qemu-xen-traditional-gnutls-compilation.patch

https://gitlab.com/johnth/aur-xen/raw/f9d0b40e240add9a136483a450c6a1b39a685808/qemu-xen-traditional-gnutls-functions.patch

after that I got

vl.c:2784:5: error: ‘g_mem_set_vtable’ is deprecated
[-Werror=deprecated-declarations]
     g_mem_set_vtable(&mem_trace);


I had to apply

https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg01262.html

which seemes that only partially been applied (has rejects), but after
modifying the sources by hand, it seemes working.

Just after this, Mini-OS failed to compile:

Makefile:17: /config/MiniOS.mk: No such file or directory

But, the MiniOS.mk DOES exists.

I had to manually add

XEN_ROOT=mysourcedir

to mini-os/Config.mk to continue. and now I'm stuck here:

Can someone advise?

So I belive, that these important patches / fixes are missing from xen
version of qemu (at least prevents compiling it without hacks on newer
systems) and also the mini-os port needs some polishing. Maybe ubuntu
has newer build tools which ones causing some incompatibilities, I do
not know.

Is it possible fixing any of these problems?

Guys.

Let me share the information I got a day ago from Pry Mar
<pryorm09@gmail.com> (attachement). He did marvellous work on xen 4.6.1+
on ubuntu 16.04.

Pls check his work, there are lot of issues there, and finally I have a
working HVM STUBDOMAIN thx to him!

http://lists.xenproject.org/archives/html/xen-users/2016-03/msg00092.html

I saw this post to xen-users. My mail client has not yet received it, so I
replied in a non-standard way.

I have had similar or same issues as you, and more, compiling this. You
will have other problems running Xen on Xenial, especially if your domU are
LVM based.

Here is my effort:
http://107.185.144.55/xen/ubuntu/xenial/46x/

I like building from the tarball, since its easier to patch (from xen root
base). Also the release tarball has qemu included. My linked build folder
also has a binary for ovmf.bin.46

If you wonder why building on Xenial is so chaotic, its because the Xen
devs/testers do not support gcc 5.x and have no interest. They only
recently started running Deb 8.x tests on their OSSTEST system.

Anthony, perhaps while you're looking at the XSA-180 backports you
could look at this too ?

(I can confirm that with qemu-xen staging-4.6, git-grep
g_mem_set_vtable produces some output, but I haven't investigated
further.  I don't know which Xen branches are affected.)

I think this should be fixed for the forthcoming 4.6 point release,
ideally.

Ian.

I've push upstream commit 98cf48f (trace: remove malloc tracing) to
qemu-xen staging-4.6 and 4.5.

In that case we'll need new tags. 4.6.3? 4.6.2.1?

4.6.2a or 4.6.2b I would say, as the main release number is still
going to be 4.6.2.

But wait - the subject says qemu-trad, which didn't get tagged yet.
Did these commits go into the qemu-xen tree really? I guess I'm
confused now...

The original report actually had 3 different issues -- the one I'm
re-raising was the one I'm personally still tripping over.  (Don't
know about the other two.)

The gnutls_kx_set_priority and g_mem_set_vtable problems don't seem
applicable to trad AFAICT.  The final problem in the bug report is a
stubdom build failure which doesn't seem to have anything to do with
qemu.  So I think qemu-trad is a red herring ?

# edit tools/Makefile to not compile xentrace
./configure --disable-qemu-traditional --with-extra-qemuu-configure-args='--disable-werror'
make

Works for me :).

Should we add --disable-werror to QEMU when doing a release? Or do we
really want to fix compilation warnings in stable branches?

I think so, yes.  Consider this case, where the new version of glibc
has this marked as deprecated -- new point releases in particular
should build without using deprecated functionality.

For this case, we can apply: 98cf48f (trace: remove malloc tracing),
which remove the offending line.
