qemu (1:2.5+dfsg-5ubuntu10.21) xenial; urgency=medium
* debian/patches/ubuntu/lp-1712803-hypercalls_backport.patch: support
newer hcalls; Thanks to Yasmin Beatriz Alves da Silva. (LP: #1712803).

Hello Po-Hsu, or anyone else affected,
Accepted qemu into xenial-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/qemu/1:2.5+dfsg-
5ubuntu10.21 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See
Waiting for the SRU Team to ack it into x-proposed now

I refreshed the tested changes on top of the security update and pushed
it for SRU review into Xenial.

Also passed all regression tests on ppc without a hickup.
Other than waiting for the security update to pass we are ready.

spapr_hcall from ubuntu_kvm_unit_test failed
** Description changed:
+ [Impact]
+
+ * Xenial with HWE kernel (matching new relesaes) and qemu without cloud
+archive (not matching new releases) could trigger hypercalls that are
+not supported in xenials-qemu.
+
+ * There is no "real" case other than kvm tests yet to trigger it
Current is 1:2.5+dfsg-5ubuntu10.16, and while there is a security update
for 1:2.5+dfsg-5ubuntu10.17 incoming we can - as discussed - test from a
ppa.
To stay ahead of the soon to be expected 1:2.5+dfsg-5ubuntu10.17 I'll
call mine 1:2.5+dfsg-5ubuntu10.18~ppa1 (actually skipping 17 for now so

One minor detail I should mention is that you're going to see 3 patches
on the file instead of 2. That is because h_page_init hypercall depends
on a function `is_ram_address` that didn't exist in v2.5. This patch has
been backported as well.

Ok Christian I'll just send the patches here then. Let me know if you
need something.

Hi Yasmins,
you can either attach the patches as files here on the LP bug or point me to a
git branch of yours that I can reach.
Unless you want to do the related packaging work as well that is all I need.
I can easily do the wrap up of the patches into the packaging for you.
TL;DR - I'm not
The patch seems easy enough, only the second has some very minor noise when
applying.
Let me know if I should do the backport or if you want to provide patches
against 2.5 (patches against 2.5 as of the qemu git is fine).
In terms of SRU scheduling I think prio is low, but it is easy enough and
Thanks for identifying the changes, both changes are in since 2.6 so I'm
first marking the bug tasks accordingly.

Steps to reproduce:
1. deploy xenial + HWE kernel on a ppc64el box
2. sudo apt-get install qemu-kvm -y
3. git clone --depth=1
https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
4. cd kvm-unit-tests
5. ./configure --endian=little; make
6. sudo ppc64_cpu --smt=off
7. sudo ./run_tests -v
Catched Po-Hsu on IRC.
He will outline the steps to get the test elf image and then we should
mirror to IBM so they can check which ppc changes would be needed. Based
on knowing that we can then decide to SRU or not.

Hi Po-Hsu,
what do you mean by "introduced by the old qemu version"?
I assume you are testing new kernels by the kernel-da-key tag?
So do you mean "the new (maybe HWE) kernel fails this test on xenial" - and
your assumption is that it triggers there because qemu doesn't have the right
fixes to
Tested with qemu-2.7.1 built from source. This test has passed on the same node.
