Hi Lukas,
There is no single "AVX instruction set", it actually consists of various
things introduced in different chip generations.
And what can be passed to the guest also depends on kernel and
qemu versions.
For a feeling of it look at `$ qemu-system-x86_64 -cpu ? | grep avx`
It is quite likely that your local test didn't have avx enabled at all.
My local autopkgtest for example specifies by default:
-cpu kvm64,+vmx,+lahf_lm
This default has no avx capabilities at all.
In a local autopkgtest you can pass qemu cpu options via:
-- qemu --qemu-options=
Unless you need to do things much more fine grained you could try
--qemu-options="-cpu host"
If still not locally reproducible, you might need to find a server with the
same chips as being used in the test infrastructure.
And you'd want to find the cpu spec that autopkgtest CPUs are run with
(this is an openstack, so there are
libvirt XMLs representing the guests and logs of the qemu commandling in
/var/log/libvirt/qemu/<guestname>.log
Look for "-cpu ..." in there
- Verify the Ubuntu delta of nss 2:3.63-1ubuntu1 regressed on s390x
